No, this is statement is false!
An absolute age is not dependent on anything - it's the age in "years" not "older than" or "younger than".
The position of rocks is more inherent to the relative age of the rocks- relative to the other layers of the rocks.
The mantle is the largest layer of the earth it takes up 84% of the earth. there are two sections in the mantle, the top is called the lithosphere and it also includes the crust. the lithosphere is a solid substance made out of dense rock that is about 1300 degrees. the bottom is called asthenosphere.
