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.

Where is the new ocean crust formed?
mid-ocean ridge
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?
it subducts underneath the crustal plate
Continental and oceanic crust?
The two parts of the crust that make up the earth. The continental supports land while the oceanic crust is at the bottom of the ocean. - Anonymous
How can the 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.
How do the ages of the rocks making up continents and those making up the ocean bottom differ?
Continental crust is normally much older than oceanic crust.
Why the crust is thinner than the ocean floor?
The crust is the Ocean floor. There is Oceanic Crust, And then There is Continental Crust.
