The Mid-Atlantic Ridge is part of the greater mid-ocean ridge system, an underwater mountain range that is over 40,000 miles long. The age of new rock closest to the ridge would be roughly the same anywhere along the ridge.

Why is the oldest rock at the bottom of the ocean?
The oldest rock is found in the continental crust. The youngest rock is found in the oceanic crust. This is because the ocean floor is recycled every 160 million years or so in the process of plate tectonics.
Which is the oldest rocks in India?
Earlier it was thought that the oldest rock of India belonged to sinngbhum craton (around 3700 my old). But as of now the oldest dated rock from India is TTG rocks from Bastar craton (roughly 3.8 by old).)
What physical characteristic of the bedrock are responsible for the oldest rock remaining at the highest elevation?
The weathered rock are left over and the new ones have to protect the old bed rocks.
Which are younger old seafloor rocks or old continental rocks?
Old sea floor rocks are much younger than old continental rocks! This is because the oceanic lithospheric plate forming the seafloor tends to be recycled at places known as subduction zones where it is forced below less dense (commonly continental) lithosphere. As such the oldest continental rocks tend to be 2-3 billion years old whereas oceanic crust neve tends to be more than a few hundred 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 is the earth 4.6 billion years old but the oldest sea floor is only 180 millions years old?
Just as new sea floor forms at mid-ocean ridges, new sea floor is forced back into the mantle at abduction zones. The oldest seafloor is at east and west the edges of the Atlantic Ocean, dating to the breakup of Pangaea.
How old are the oldest rocks found on the moons?

How old are the oldest of the ocean floor?
Less than 200 Million years old.
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.
What age is the oldest rocks from the seafloor?
The oldest rock are up to 125 million years old.
Is granite the oldest rock in the world?

Is the age of the sea floor the same age of the continents?
No. The sea floor is much younger than the continents. The oldest sea floor is about 200 million years old. The continents are billions of years old.
