The Cocos Plate was created approximately 23 million years ago when the Farallon Plate broke into two pieces, which also created the Nazca Plate. Error message | View complete answer on https://www.britannica.com Are the Nazca Plate and South American plates divergent plates? Spreading rates vary considerably, from 2 cm/y to 6 cm/y in the Atlantic, to between 12 cm/y and 20 cm/y in the Pacific. Transcribed image text: Question 1 (1 point) Saved Unclick all the other layers you've been using, and then click next to "plate boundary model" layer. This plate is in the Pacific Ocean between the Pacific plate and the South America plate. The eruption of Mt. * The boundaries that moving away . This contortion attests to the great forces that squeezed and lifted the layers from the sea. The rising hot water causes overlying rock to melt, generating magma that at times erupts out on the surface as lava flows and other materials forming Mt. Volcanic and metamorphic rocks exposed in Kenai Fjords National Park reveal the incredible forces that occur at an ocean/continent subduction zone. Mazama, Aniakchak no longer holds a large lake because the caldera wall is breached. This plate is small. The Pacific Northwest is an exciting place to observe geologic processes in action. South America plate, Pacific plate, Antarctic plate, Cocos plate. Olympic National Park, Washington What boundary is between the Cocos Plate and the Caribbean plate Transform Plate Boundaries - Geology (U.S. National Park Service) Mazama that formed Crater Lake. Roughly 3.2 million square kilometres (1.2 million square miles) in area, the Caribbean Plate borders the North American Plate, the South American Plate, the Nazca Plate and the Cocos Plate. The Pacific Plate is moving to the northwest at a speed of between 7 and 11 centimeters (cm) or ~3-4 inches a year. Chapter 2 Flashcards | Quizlet Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust. Subduction zones form where a plate with thinner (less-buoyant) oceanic crust descends beneath a plate with thicker (more-buoyant) continental crust. Lake Clark National Park and Preserve contains an active composite volcano with a profile and recent history reminiscent of Mt. 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. Question: Tectonic Plates Use this map to answer the following questions. The explanation is that plates move in a rotational manner. Some transform faults connect continental parts of plates. The Cocos Plate in the Pacific Ocean is subducted beneath the Caribbean Plate, just off the western coast of Central America. During the same period, the Atlantic Ocean began to open up between northern Africa and North America, and India broke away from Antarctica. This plate is small. Once this happens, the continents will no longer continue to move apart because the spreading at the mid-Atlantic ridge will be taken up by subduction.
