Where would I find the oldest rock on the ocean floor?

The oldest rock on the ocean floor can be found in the central parts of the ocean basins, particularly in regions known as abyssal plains. These rocks are generally around 200 million years old or older.


Where does the oldest rock take place at on the ocean floor in sea-floor spreading?

Far from the mid oceanic ridge, near the continental margin (oldest oceanic rock ages 200 mya)

What happen to the oldest rock on the ocean floor to continue the rock cycle?

Or they get subducted and re-enter the mantle or they get obducted onto continent (the latter being called an ophiolite).


Where would you expect to find the oldest rock on the oldest 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.


How would the age of the oldest rocks on the continents compare with the age of the oldest rocks on the seafloor if the rock on the continents is continually formed but not removed?

The oldest rocks on the continents would be much older than the rocks on the sea floor because the rocks on the continents are not being removed unlike the rocks on the sea floor that are made by the mid-ocean ridge are being removed by deep ocean trenches. this prossess that is occuring on the sea floor is called sea floor spreading. evidence of this is the Pacific ocean shrinking and the Atlantic ocean growing.

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 are the oldest part of the ocean floor no older then about 200 million years old?

The ocean is 4 billion yars old, however due to subduction, the oldest sediment found in the ocean's floor is 180 million years old.

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.
