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.

How does the age of oldest continental crust compare to the age oldest ocean crust?
The oldest continental crust is significantly older than the oldest oceanic crust. The oldest continental rocks, found in regions like Canada and Australia, are over 4 billion years old. In contrast, the oldest oceanic crust, located at the bottom of the Atlantic Ocean, is only about 200 million years old, as it is continuously created and destroyed through the process of plate tectonics. This stark difference highlights the stability and longevity of continental crust compared to the dynamic nature of oceanic crust.
What type of rock is the oldest continental crust made of?
Granite
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 oceanic crust is considerably than the oldest continental rock?
Oceanic crust is more dense than continental crust. As a result, over time, continental crust is harder to "recycle". Rocks are recycled when they are subducted and remelted. Since continental crust is harder to subduct (it wants to keep floating), it is not recycled as much as oceanic crust, which is dense and will sink and remelt.
