So the…um…the oceanic plate is made of denser and heavier rock, so it begins to sink down under the continental plate and into the mantle. Professor: Right. So the ocean floor would kind of slide under the edge of the continent. And once the ocean plate begins to sink, it would ...
But some volcanoes occur … not at the edges, but in the middle of a continental or oceanic plate.The Hawaiian Islands for example, are thousands of kilometers away from any plate boundary. And yet, you have vast amounts of magma—molten rock or lava—flowing up through the Earth's crus...

Plate tectonics play an important role in shaping our planet. It is responsible for mountain range formation, oceanic trenches and occurrence of earthquakes and volcanoes among many other geologic phenomena. What moves the Tectonic Plates? Heat in the earth’s core makes the tectonic plates move th...
Oceanic PlateAsian ContinentLateral Strike SlipThe main unusual feature of tectogenesis of the Asian–Pacific transition zone in the Mesozoic–Cenozoic consists in the formation of left-lateral strike-slip faults, which form the East Asian global shear zone with paragenesis of its constituent variously...
If one of the colliding plates is topped with oceanic crust, it is forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into new crust. Magma formed from melting plates solidifies into granite, a light colored, low-density rock tha...

Question: What are Earth's plates? Plate Tectonics: Plate tectonics refers to a theory that consists of the movement of the seven large Earth plates and the movement of the other smaller plates on Earth's lithosphere. The tectonic process began about 3 to 3.5 billion years ago. ...
