How does the age of the oldest continental crust compare to the of the oldest ocean crust?
The oldest continental crust would be between three and one half to four billion years older than the oldest oceanic crust. This is due to the fact that ocean plates are subducted under the continental plates, subjected to partial melt and essentially recycled in the mantle before reforming.

What type of rock is the oldest continental crust made of?
Granite
Deep ocean sediments are thickest where the underlying crust is?
oldest
Why are the oldest parts of the ocean floor no older than about 200 million years.?
Because the oldest parts reach the continental crust and then the ocean floor sinks beneath the continental crust, into the mantle.

Why is the oldest seafloor crust found farthest from a mid-ocean ridge?
because the older crust is pushed out by the newer crust that is forming
