The oldest rocks are actually on land but in the ocean crust they would be the rocks closest to land. The mid-ocean ridge forms new rocks. They are usually located in the middle of the ocean.

Where are the oldest rocks located in the ocean crust?
The oldest rocks on the ocean floor would be those at the colliding edge of the plate boundary.Answer 2: The oldest of all oceanic rocks are on the Asian side of the pacific plate.
Where would you expect to find the oldest on the ocean floor?
Somewhere at the bottom of the Marianas Trench you would find the oldest rock of the oceanic crust. Somewhere else, however, there are older rocks on the ocean floor--those deposited by icebergs that have broken off of glaciers. Those erratic rocks could be much older than the oldest oceanic crust.

Are the oldest rocks on land or in the ocean?
The oldest rocks are found on land.
Which has the younger rock the continental crust or oceanic crust?
The youngest rocks will be formed from cooled magma. Therefore volcanism, either on the continental crust or oceanic crust will create the youngest rocks.

Are the oldest rocks of the oceanic crust found in deep ocean trenches far away from active mid-ocean ridges?
That is normally where they would be found; farthest away from the point at which they were initially formed.
On the ocean floor where is the oldest rock?
The oldest rock in oceanic crust is that which is found the greatest distance from a mid-ocean-ridge.
Rocks in ocean crust are as old as?
200 million
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.
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.
