cocos plate and north american plate boundary type

This boundary here that I am marking in red is the boundary between the ocean and the land. African Plate — South American Plate. Juan de Fuca Plate — Pacific Plate. The earthquake to hit Mexico occurred because there was a reverberation along the boundary between the Cocos and the North American plate – causing a seismic ripple. The North American Plate is one of the slowest, averaging around 1 cm/y in the south up to almost 4 cm/y in the north. Note: the key to identifying the types of plate motions is displayed in the Legend window. Notably, there are two “flat-slab” subduction zones between 2°-15°S and 28°-33°30’S that and are distinguished by the lack of late Miocene to Holocene volcanic activity (Gregory-Wodzicki, 2000) (Figure 3). Plates move as rigid bodies, so it may seem surprising that the North American Plate can be moving at different rates in different places. These two plates are sliding past each other in some areas and converging The Cocos Plate, running along the ocean floor off the Pacific coast of Central America, moves 75 mm or 3 inches a year -- almost 25 feet per century. If the data are asymmetric at a particular boundary type, devise a way of indicating that on your plate boundary map. The first type, the high-rate model (Bandy, 1992), predicts convergence rates of approximately 5.0 cm/yr near the southern end of the Rivera-North America subduction zone and between 2.0 and 3.0 cm/yr at its northern end. This provides an estimated 125 miles of room for S America to roll to the west, but the plate boundaries in the central Pacific have also been steadily adjusting. The Caribbean Plate lies in a complex area. Arrows along the boundary between the South American Plate and the Nazca Plate point toward each other, indicating that the boundary between these two plates is a convergent boundary. On Tuesday, a deadly quake reverberated along the boundary between the Cocos and the North American plate as the southern-most plate slid beneath its … Convergent plate boundary. The east-side of the North American Plate straddles the Eurasian Plate and African Plate.This is the Mid-Atlantic Ridge where divergent tectonic plates pull apart from each other. Cocos Plate One of the present-day minor lithospheric plates that lies beneath the Pacific Ocean.A remnant of the Farallon Plate, it is subducting under the North American Plate and Caribbean Plate and has constructive boundaries with the Pacific Plate (along the E. Pacific Rise) and the Nazca Plate (along the Galápagos Rise). The western boundary is another mid-ocean ridge, the East Pacific Rise. 1. convergent. These are plates that are greater than 20 million square kilometers. (Fig 4-1) Italy itself sits near the border between two plates the Eurasian plate and the North African plate. Over time, the plates scrape against and collide into each other, forming mountains, trenches and other geological features. 8.2). The Juan de Fuca plate is an oceanic plate and the North American plate is a continental plate.. Overall S America now has 250 miles to roll, dragging the Caribbean and pushing over the Cocos and Nazca plates before it. 2. Cocos Plate — Pacific Plate. tectonic plate Boundaries World Map, tectonic plate tectonic plates, boundaries, plates, tectonic, plate, World Map, North American Plate, Juan de Fuca plate, Cocos Plate, Eurasian Plate, Filipino Pla In the west, it borders the Central American subduction zone where the Cocos plate subducts in NNE-ward direction (DeMets, 2001 ). answer choices . The Pacific Plate is the largest of the 7 major tectonic boundaries.With a size of 102,900,000 km 2, it more than doubles the size of the South American Plate.. One of the large plates is the North American Plate.This plate includes most of the North American continent, Greenland, and part of Iceland and Siberia. Plate motions in cm/yr for Caribbean-North American plates are from Demets et al. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries. North American Plate . North American plate and the South American plate. This tearing event may be a young analogy to the 10 Ma Rivera-Cocos plate boundary, and may be related to the slab rollback The first type, the high-rate model (Bandy, 1992), predicts convergence rates of approximately 5.0 cm/yr near the southern end of the Rivera-North America subduction zone and between 2.0 and 3.0 cm/yr at its northern end. The earthquake epicenters outline the limits of the Rivera plate along the Tamayo and Rivera Fracture zones, East Pacific Rise and Middle American trench and its boundary with Cocos plate. The most obvious type of boundary is a physical boundary. Juan de Fuca Plate (west of Washington State) Nazca Plate . All along that coast is a tectonic border, between the Cocos Plate in the ocean, and the North American, Caribbean, and Panama Plates that make up the Central American land mass. Rates of motions of the major plates range from less than 1 cm/y to over 10 cm/y. Mt St Helens is on the plate boundary between Juan de Fuca and the North American plates, the boundary is also a part of the Ring of Fire. The approximately 80 million year old Caribbean Plate is roughly rectangular, and it slides eastward at about two centimeters/year relative to the North American Plate. Pacific Plate 3. Tectonic sketch map of the Caribbean area. The North American Plate consists of the Mid-Atlantic Ridge, which is a chain of mountains underneath the Atlantic. The southern boundary is a mid-oceanic ridge, the Galapagos Rise. The Cocos Plate is a triangular shaped young oceanic plate that is around 2,900,000 km2 2,900,000 k m 2 in area. North American Plate. The North American plate is moving to the west-southwest at about 2.3 cm (~1 inch) per year driven by the spreading center that created the Atlantic Ocean, the Mid Atlantic Ridge. These plates move and interact with one another to produce earthquakes, volcanoes, mountain ranges, ocean trenches and other geologic processes and features.Map prepared by the United States Geological Survey. Extending the entire length of South America, the margin is punctuated by the deep Peru-Chile trench where the Cocos, Nazca, and Antarctic plates are converging with and sinking beneath the South American plate. The word, tectonic, refers to the deformation of the Lithosphere as a consequence of plate interaction. Earthquakes are caused by movement in the earth's tectonic plates. Caribbean Sea covers most of the plate. Identify the type of plate boundary convergent, divergent, or transform) that is occurring at the following locations: 1. Small unmapped fractures are shown in perspective diagrams of Figure 5. An intense temblor in Mexico was just the latest example of an enigmatic type of … The boundary of the Antarctic and South American plates coterminous with the Scotia Plate 3. A distinct sur-ficial manifestation from the Cocos plate subduc-tion is the Trans-Mexican Volcanic Belt (TMVB, An example of this type of late boundary can be seen north of Haiti, where the Caribbean Plate rubs against the North American plate. the Mid-Atlantic Ridge, made up of the boundary between the North American and Eurasian Plates in the North Atlantic, crossing Iceland, and the South American and the African Plates in the South Atlantic. Earthquakes are caused by movement in the earth's tectonic plates. 4. South American Plate 5. In turn, we find some of the youngest geologic rocks at these mid-oceanic ridges. Scotia Plate Nazca Plate Antarctic Plate Cocos Plate South American Plate Caribbean Plate Philippine Plate Juan De Fuca Plate All the Tectonic Plates are shown in the picture above. Plate Tectonics Summary •The Earth is made up of 3 main layers (core, mantle, crust) •On the surface of the Earth are tectonic plates that slowly move around the globe •Plates are made of crust and upper mantle (lithosphere) •There are 2 types of plate •There are 3 types of plate boundaries •Volcanoes and Earthquakes are closely Australian Plate . Plate Boundaries Type of Boundary Pacific Plate – Nazca Plate Divergent Pacific Plate – Cocos Plate Divergent From the top of Cocos Plate – Top of North American to the curve Transform Cocos Plate – North American Plate Convergent Cocos Plate – Caribbean Plate Convergent Caribbean – North American Plate Transform … The Cocos plate subducts under the North American plate with a complex geometry, and previous seismicity studies revealed some of this complexity. The San Andreas Fault in California is a part of the boundary between the . The Yellowstone Geyser is a famous example of the active seismic activity under the plates. Plate Boundaries are the borders between where two Tectonic Plates meet and interact with each other. The Cocos Plate is bounded by several different plates. The boundary between the North American Plate and the Eurasian plate is driving tectonic activity in Iceland while the boundary beteen the Eurasian and African plates … The boundary between the North America Plate and the Eurasian Plate is an example of a divergent boundary at a mid-ocean ridge. COLOR your Plate Boundary Map to locate your group's boundary types. Haiti is situated to the north of the Caribbean plate, on a transform or conservative plate boundary. Hereof, what type of plate boundary is Mt St Helens on? The Pacific Plate contains all the plate tectonic boundary types along its boundary. In other words, it shares convergent, divergent and transform borders with other plates. The southern edge is a divergent plate boundary with the Antarctic Plate. Caribbean Plate . 3 types of plate boundaries:! Richard J.F. North American Plate 2. Remnants of the ancient volcanic mountain chain remain. According the theory of plate tectonics, Earth's outer shell is made up of a series of plates.The map above shows names and generalized locations of Earth's major tectonic plates. To the south west lie the Nazca Plate and Cocos Plate . The North American Plate is one of the slowest, averaging around 1 cm/y in the south up to almost 4 cm/y in the north. North American Plate . d. Pacific plate and the North American plate. The North American Plate consists of the Mid-Atlantic Ridge, which is a chain of mountains underneath the Atlantic. Australian Plate 8. This tectonic plate borders four other plates which include the Cocos Plate, Nazca Plate, South American Plate and the North American Plate. A transform plate boundary occurs when two plates slide past each other, horizontally. Since 2004, temporary experiments and the expansion of the permanent network of the Servicio Sismológico Nacional (SSN, Mexican National … Volatile trenches along the Cocos plate generally have had seismic events 30 to 70 years before 1985. Describe the relative motion between the North American Plate and the Pacific Plate. At strike-slip plate boundaries, two plates slide past one another horizontally; along the San Andreas fault in California, for example, a portion of the Pacific plate slides northward relative to the North American plate. Which plate is being subducted? Prior to 20 Title: Plate_Boundaries.ppt The Caribbean plate is roughly rectangular, and it slides eastward at about 2 cm/yr relative to the North American plate. At what type of plate boundary do the deepest earthquakes occur? Plates move as rigid bodies, so it may seem surprising that the North American Plate can be moving at different rates in different places. About 100 km offshore, the Acapulco Trench (also known as the Middle American Trench) forms the boundary between the Cocos Plate and the North American Plate. Haiti is situated to the north of the Caribbean plate, on a transform or conservative plate boundary. 4. Task 1: Each person should make a brief presentation to the rest of their group about their Scientific Specialty and associated classification scheme. Wessels, in Transform Plate Boundaries and Fracture Zones, 2019 2.1 Geodynamic Setting. The Cocos Plate is one of the pieces of rock that make up the topmost levels of the earth's surface (or lithosphere). deep sea trench ... Cocos Juan de Fuca North American. 5. Examine the interact-able globe on the Pacific Ring of Fire Slide: Find the Mariana Subduction Zone at the boundary between the Pacific (PA) and Phillipine Plate (PH). The blue blob in the cutaway section is the Farallon Plate, which is subducting beneath North America. a. Cocos plate and the Nazca plate. • For Example: Alaska-Aleution Islands have lots of earthquakes because it is part of the North American Continental crust Convergent Plate boundary and the subducting Pacific Oceanic crust. Day 2: Assemble in your Plate groups. • Or maybe the location has Drilling (Fracking) Activity… surrounding Volcanoes, Faults, etc. As such, the region is no stranger to quakes and tremors as the edge of the Cocos Plate moves beneath the continental plates. boundaries, and CNS denotes Cocos-Nazca spreading center crust [Barckhausen et al., 1998]. The Yellowstone Geyser is a famous example of the active seismic activity under the plates. The eastern and southeastern parts of the Pacific Plate jostles against the Juan de Fuca, Cocos, and Nazca Plates, which are subducting under the North American Plate. Over time, the San Andreas transform plate boundary has grown longer as the Farallon Plate split into two separate plates—the Juan de Fuca Plate on the north, and the Cocos Plate on the south. New Zealand sits on the boundary of two of these plates, known as the Indo-Australian plate and the Pacific plate. Nazca Plate — Pacific Plate. Tectonic and topographic setting of the Central American arc (volcanic arc segments 2–5), Trans-Mexican volcanic belt (segment 1) and the Middle America trench. Antarctic Plate . [1] A global set of present plate boundaries on the Earth is presented in digital form. Indian Plate 10. Iceland lies on the Mid Atlantic Ridge, a constructive plate margin seperating the North American plate and the Eurasian plate. The southern border of the Nazca plate is divergent from the Antarctic plate; the western border is also divergent with the plate of the Pacific, and the north with the plate of Cocos. Modern-day plate configurations can convergent divergent transform fault all of these are plate boundaries. The Caribbean plate moves at 20 mm/year east-northeastwards with respect to the North American plate (DeMets et al., 2010 ). On the other side of this arc of volcanoes, the Arenal graben and the Valle Central make up a basin. Plate tectonics are odd because they often consist of oceanic and continental crust.For example, the Pacific Plate underlies the Pacific Ocean with the Hawaiian Islands positioned smack dab in the middle. The eastern edge of the plate is in a subduction zone beneath the South American plate, and this crash has given rise to the Andes Mountains. Water released from the subducting slab causes the overlying mantle to partially melt, forming magma that sustains the Cascade Range of volcanoes (black triangles). Examine the interact-able globe on the Pacific Ring of Fire Slide: Find the plate boundary between the Cocos Plate (CO) and the North American Plate (NA). The Pacific Plate is the fastest at over 10 cm/y in some areas, followed by the Australian and Nazca Plates. As the Juan de Fuca Plate drifts eastward, it cools, becomes more dense, and eventually dives under the less dense North American Plate at the Cascadia Trench. This is a transform plate boundary, and the Cocos plate lies to the west and this is a converging plate boundary. The new calculations showed the Pacific plate is pulling away from the North American plate a little more -- approximately 2 millimeters a year -- than the rigid-plate theory would account for, he said. As the mid-ocean ridge separating the Farallon and Pacific Plates entered the subduction zone, the Farallon Plate separated into the Juan de Fuca and Cocos Plates. Another divergent plate boundary is the East Pacific Rise, which separates the massive Pacific plate from the Nazca, Cocos, and North American plates. The Cocos plate, and the Rivera plate at an oblique angle are diving under the North American plate at this boundary. The Cocos Plate is a young oceanic tectonic plate beneath the Pacific Ocean off the west coast of Central America, named for Cocos Island, which rides upon it. The Caribbean Plate is a mostly oceanic tectonic plate underlying Central America and the Caribbean Sea off the north coast of South America. These two major plates and two minor plates bordering it includes oceanic and continental crust. Scotia Plate — South American Plate. The presence of smaller plates, like the Juan de Fuca and Cocos plates off the Paciic Coast of North America, are clues of a larger pre-existing Farallon plate which was subducted underneath the North American plate. Part of this volcanic range is a horst due to extreme block-faulting. The plate is around 23 million years old, which is relatively young in tectonic plate terms. Triple junction denotes fossil triple junction which merges with rough-smooth boundary (Plate I inset). The extent of Figure 5a is indicated by the line along the Nicoya Peninsula. Furthermore, is Mount St Helens the Cascade Range an example of a convergent … divergent plate boundary between the Pacific Plate and the North American Plate. Tectonic plates are made up of Plate Boundaries. The crustal thickness of the Caribbean Plate varies from, 6-8 km, west of the Beata Ridge, to 20 km between the Central Venezuelan and the western part of the Beata Ridge until, 3-5 km in the southeast of the Venezuela Basin (Diebold & Driscoll, 1999).The crust varies also in thickness from Yucatán Basin (8-9 km, Hall 1995) to Colombian … Where the plates meet, their relative motion determines the type of boundary: convergent, divergent, or transform. The devastating 1985 Mexico City earthquake was a result of the subduction of the Cocos Plate beneath the North American Plate. ... COCOS PLATE A volcanoes Arc NORTH AMERICAN RATE . Located on the other side of the Pacific Ocean, volcanism is caused by the subduction of the much smaller Cocos Plate beneath the North American-Caribbean Plate. Cocos/Nazca/Caribbean Plates 7. The Pacific Plate is the fastest, followed by the Australian and Nazca Plates. divergent. Along the western border of the North American plate in a dextral transform fault lies the Pacific plate (Nicholson, 1994). As the plates move apart magma fills the magma chamber below Eyjafjallajokull. A belt of volcanoes extends from northern Panama to western Mexico, and virtually all of the highest mountains in this belt are volcanic. Nazca Plate — Cocos Plate. Furthermore, where are plate boundaries located? The northern boundary of the Cocos Plate is the Middle America Trench. The eastern boundary is a transform fault, the Panama Fracture Zone. The southern boundary is a mid-oceanic ridge, the Galapagos Rise. The western boundary is another mid-ocean ridge, the East Pacific Rise . North American Plate Movement. A) convergent B) divergent ... the Cocos Plate B) the Nazca Plate C) the Juan de Fuca Plate D) the Pacific Plate. A transform plate boundary developed where the Pacific Plate was in contact with the North American Plate and the volcanism ceased in central California. A well-known transform plate boundary is the San Andreas Fault, which is responsible for many of California’s earthquakes. the boundary between the Pacific and Antarctic Plates. The boundary between the two plates appears to lack a definite transform fault, yet they are regarded as distinct. Eurasian Plate . We classify plates into three groups depending on their size – Major, Minor, and Micro plates. Plates move as rigid bodies, so it may seem surprising that the North American Plate can be moving at different rates in different places. What is the name of the large supercontinent that existed 200 million years ago when all of the continents were together? The East Pacific Rise off South America and the Gorda Rise off the Pacific Northwest are remnants of a once-continuous plate boundary that separated the Pacific Plate and a now mostly-vanished plate called the Farallon Plate. Southern and Western Dynamics. The remnants of this plate on the surface of the Earth are the Juan de Fuca Plate and Explorer Plate, both in the northwestern United States and southwestern Canada and the Cocos Plate … A single tectonic plate can have multiple types of plate boundaries with the other plates that surround it. Caribbean Plate — South American Plate. Each person should mark the boundary types identified by the group on their own map. By minor, it means small. The Juan de Fuca, Explorer, Gorda, Rivera, Cocos and Nazca plates are remnants of … The North American plate lies to the north and to the east and it is converging. Subduction of the Pacific plate beneath the North American plate in the north creates the long chain of the Aleutian Islands volcanoes near Alaska. Pacific ----- Cocos . The eastern edge of the plate is in a subduction zone beneath the South American plate, and this crash has given rise to the Andes Mountains. [3] The Cocos plate has been subducting under-neath the North American plate for about 16 Ma [Pardo and Suárez, 1995] since it became detached from the Farallon plate at about 25 Ma [Wortel and Cloetingh, 1981; Lonsdale, 2005]. New seafloor is created at a _____. North American Plate Philippine Sea Plate Pacific Plate Scotia Plate South American Plate These plates move because of convection currents that occur beneath them in the semi-molten layers of the Earth. The comprehensive theory which tries to explain most of the dynamism of earth crust and features of the endogenetic forces.. 3. The southern border of the Nazca plate is divergent from the Antarctic plate; the western border is also divergent with the plate of the Pacific, and the north with the plate of Cocos. The eastern boundary is a transform fault, the Panama Fracture Zone. TECTONIC PLATES. The deepest earthquakes occur within the core of subducting slabs - oceanic plates that descend into the Earth's mantle from convergent plate boundaries, where a dense oceanic plate collides with a less dense continental plate and the former sinks beneath the latter. (1) Describe how they are moving, and the type of plate boundary located there. It is 75,900,000 sq km. A physical boundary is a naturally occurring barrier between two areas. Tags: Question 29 . A) convergent B) transform The formation of the Cocos Plate can be traced to seafloor spreading, which generally occurs at mid-ocean ranges. Subduction ended when the ancient Farallon Plate was overrun as North America moved westward, overriding the northern end of the spreading center in the Eastern Pacific basin (Figure 7.62). Review the plate boundaries section of your textbook, along with Figures 11.25, 11.26, and 11.27. Pacific Plate – 103,300,000 km 2; North American Plate – 75,900,000 km 2; Eurasian Plate – 67,800,000 km 2 These move … Both quakes were sparked by heightened tension between the Cocos tectonic plate, which borders the western coast of Mexico, and the North American … The volcano lies on the Trans-Mexican Volcanic Belt, which is the result of the small Cocos Plate subducting beneath the North American Plate. The North American Plate is one of the slowest, averaging around 1 cm/y in the south up to almost 4 cm/y in the north. This solid material is called the lithosphere. The Cocos plate is surrounded by the Pacific, Nazca, Caribbean and North American plates. E. The M8.2 earthquake was a mega-thrust quake; the M7.1 earthquake was an intraplate quake in the overriding North American plate. three types of plate boundaries. !divergent !! Plate boundaries are found at the edge of the lithospheric plates … Summary. Tags: ... curved chains of oceanic islands associated with seismic activity and mountain-building processes at certain plate boundaries. Pacific Plate . To the north of the Caribbean Plate lies the North American Plate and to the south of it lies the South American Plate. NORTH AMERICAN PLATE EURASIAN PLATE EURASIAN PLATE JUAN DE PULA her PLATE CARIBBEAN PLATE PHUPPINE PLATE ARABIAN PLATE COCOS PLATE INDIAN PLATE EQUATOR AFRICAN PLATE PACIFIC PLATE NAZCA PLATE SOUTH AMERICAN AUSTRALIAN PLATE PLATE AUSTRALIAN PLATE SCOTIA PLATE ANTARCTIC PLATE There are 3 different plate boundary … Western Mexico, where the young and small Rivera Plate and the adjacent large Cocos Plate are subducting beneath the North American Plate, is a unique region on Earth where tearing of subducting oceanic plates, as well as fragmentation of the overriding continental plate, is … Other plate boundaries are classified into one of 6 types according to whether they are oceanic or continental, and whether their relative velocity is divergent, strike-slip, or convergent. NORTH AMERICAN PLATE EURASIAN PLATE EURASIAN PLATE JUAN DE PULA her PLATE CARIBBEAN PLATE PHUPPINE PLATE ARABIAN PLATE COCOS PLATE INDIAN PLATE EQUATOR AFRICAN PLATE PACIFIC PLATE NAZCA PLATE SOUTH AMERICAN AUSTRALIAN PLATE PLATE AUSTRALIAN PLATE SCOTIA PLATE ANTARCTIC PLATE There are 3 different plate boundary categories: Convergent, … SURVEY . In the case of the Haiti earthquake, the Caribbean and north american plates slid past one another causing friction, therefore creating an earthquake. Figure 8.1 (right). The triple junction of the North America, Cocos, and Caribbean plates is ambiguously defined, mainly because the North America‐Caribbean plate boundary does not clearly continue beyond its known surface trace (the Motagua fault zone) in western Guatemala to intersect the Middle America trench. The Cocos Plate pushes against and slides under the North American Plate, primarily along the coasts of the states of Michoacán and Guerrero in Mexico. The Rivera-Cocos plate boundary zone is a complicated across-trench tectonic structure (Fig. The Plates or Plate Groupings are: 1. How many people died in the 1985 earthquake in Mexico? The Pacific Plate is the fastest, followed by the Australian and Nazca Plates. As they collide, the edge of one or both plates may be forced up into a rugged mountain range, like the Himalayas, which formed at the boundary of the Eurasian and Indian plates (the Indian plate is now part of the Indo-Australian plate).
