The quake struck with a moment magnitude of 6.9 on October 17, just before the start of the third game of the World Series, which was being held at San Francisco's Candlestick Park. In addition to the transform fault, the Puerto Rico Trench is also associated with a subduction zone . How have tectonic plates influenced landforms in Western Canada? This helps to create volcanoes inland from the subduction zone that marks the border between the two plates. As they pull apart, the mantle material beneath rises to create new crust on the ocean floor. The Eurasian Plate is the third largest major plate. Sheila has a master's degree in geology and has taught middle school through university-level science courses. The North American plate consists of a single craton, the Laurentia craton, with smaller terrains sutured to it (Bally 1989). It consists of most of Europe, Russia, and parts of Asia. {{courseNav.course.mDynamicIntFields.lessonCount}} lessons Research the exact locations of these plate boundaries and draw them on your map. The North American continent is rich in major mountain peaks. We have already mentioned plates moving and new crust being formed where mantle material rises to the surface. Recently formed rocks can also be found anywhere lava erupts from a volcano, which we mentioned often happens near subduction zones. In the western part of the continent, divergent plate boundary forces are beginning to rip the continent apart, forming the Basin and Range Province and its adjacent eastern arm, known as the Rio Grande Rift . Like other continents, North America has thick crust, compared to the thin crust beneath the adjacent Atlantic and Pacific oceans. So far, we've only discussed the North American Plate's boundaries. 's' : ''}}. Plate tectonic forces ripped the continents apart and moved the continental fragments and oceanic islands over great distances, where they eventually collided with the edge of North America. So, as we think about the plates on the Earth's surface moving, let's move on to a sandwich-cookie model even though it doesn't have a sphere or Earth-like shape.

Like seams of a baseball, tectonic plates wrap around Earth. The Indian plate is located in the northeast hemisphere and it’s bounded by four major plates; Eurasian plate (North),… North American Plate One of the present-day major lithospheric plates, the N. American Plate extends from the Mid-Atlantic Ridge in the east to a complex pattern of subduction zones and transform faults which form its boundaries with the Pacific, Juan de Fuca, Gorda, Cocos, Caribbean, and South American Plates in the west and south. The North American major plate not only contains the continent of North America but also part of the Atlantic Ocean. One of the large plates is the North American Plate. Volcanoes are also found in the Pacific Northwest. As the Pacific Plate subducts, some pieces of the crust scrape off onto the North American Plate. The plate includes both continental and oceanic crust. The North American plate is responsible for the formation of the Mid-Atlantic Ridge, a mountain chain beneath the Atlantic Ocean. There are a few handfuls of major plates and dozens of smaller, or minor, plates. Africa sits on two tectonic plates. Both convergent and divergent movement is also found on the 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. North America Plate has been shaped into a profile of the United States like those we often see in souvenir stands at Yellowstone or Mount Rushmore. What is an active volcano in the Rocky Mountains? Much like in our cookie model, the plates get stuck and, rather than moving smoothly and continuously, they push past each other in short bursts that we feel as earthquakes. The plate is presently shrinking as the Atlantic Ocean increases in size pushing the North American Plate slowly westward. It has a divergent boundary with the Explorer Plate off the west coast of Vancouver Island, Canada. To begin, let's consider the Earth and its layers. However, most of the dense sinking plate gets pulled into the mantle where it melts into the surrounding material. {{courseNav.course.topics.length}} chapters | A part of the subduction zone measuring approximately 190 miles (300 km) long by 95 miles (150 km) wide lurched as much as 164 feet (50 metres) to the east-southeast and thrust upward about 33 feet (10 metres).…, …Plate (west) relative to the North American Plate (east) along transform faults.
