What is ocean to continent subduction?

Ocean crust is forced under continental crust because the former (ocean) is denser than the latter (continental). Much the same effect occurs when cold air is forced under hot (MORE)

What happens to the plate that subducts?

How does subduction occur?

Subduction occurs when two plates collide and one plunges beneath the other. The two plates are Oceanic plate and Continental plate. Oceanic plate sinks, because it's denser t (MORE)

Why is subduction necessary?

Because if there wasn't subduction the earth would get bigger and bigger caused by sea floor spreading (in the ocean new ground is formed when two plates spread apart) and lav (MORE)
