Rocks in ocean crust are as old as?
200 million
Are oceanic rocks billion years old?
No. Oceanic crust is recycled into the mantle through a process called subduction and new ocean floor is formed at mid-ocean ridges. None of the ocean floor is more than about 180 million years old. Some rocks on the continents are billions of years old.
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.
Rocks in continental crust are as old as years.?
44 million
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.
Rocks in ocean crust are as old as years.?

Rocks in ocean crust are as old as how many years?
200 million.

How old are rocks in ocean crust?
The age of rocks in the ocean crust depends on where the rocks are collected. Scientists collected rock samples from the sea floor. They found out that rock samples that were closer to mid-ocean ridges were younger than the samples farther away from the ridges. So pretty much you could get rocks that are thousands of years old to over millions of year old.

What does ocean crust mean in science?
The oceanic crust is the part of the earth's crust that is below the ocean. The rock that makes up the oceanic crust is about 200 million years old.
Rocks in continental crust are as old as years.?
44 million
Rock in ocean crust are as old as how many years?
200 million.
How old are the oldest rocks of the ocean?
Less than 200 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.
Why havent older ocean rocks been discovered?
Oceanic crust is eventually destroyed in subduction zones. Although oceanic crust has been forming on Earth for over 4 billion years, all of the sea floor older than about 200 million years has been recycled by plate tectonics. Continental crust is not subducted and destroyed, so very old continental rocks have survived.
