Where is the new ocean crust formed?
mid-ocean ridge
How can the ocean crust be different ages?
On geologic time scales, new oceanic crust is constantly being formed ad mid-ocean ridges while older crust is destroyed at subduction zones. The crust forms at the ridge and is carried away by the movement of the plate as new crust forms to take its place. The oceanic crust is youngest new a mid ocean ridge and oldest far away from it.
Does theory continental drift state that new ocean crust is formed at ocean ridges and destroyed at deep sea trenches?
No, the theory is that Seafloor spreading state that the new ocean crust is formed at ocean ridges and is destroyed at deep sea trenches.
When the ocean floor collides with a crustal plate what happens?

If volcanoes get their magma from the crust below them what can you say about the silica contents of Earth's crust under the ocean?
You can say that it is low in silica. -I had this problem in my science class ^_^
Why the crust is thinner than the ocean floor?
