Theory of Plate Tectonics - ANSWER A theory stating that Earth's lithosphere is broken into huge plates that move and change in size over time - explains the process of continental drift - theory is a fusion on the theories of continental drift and seafloor spreading - continents are not floating on the ocean, rather they are rooted What are the 10 major plates of the Earth's lithosphere? - ANSWER African, Antarctic, Australian, Eurasian, North American, South American, Pacific, Cocos, N...

Describe what happens when two tectonic plates collide along a subduction zone. correct answers One plates moves under another and sinks into Earth's mantle. A trench may be formed Explain how subduction leads to volcanic activity correct answers One plate is pushed down and melted as molten material/ magma rises to the surface near the zone What areas exhibit island arcs correct answers Coast of Asia (Philippines, Ryukyu, Japan, Kuril, and Aleutian) What areas exhibit a growing nonvol...
