What is the purpose of lithosphere?

The lithosphere is largely important because it is the area that the biosphere (the living things on earth) inhabit and live upon. If it weren’t for the tectonic plates of the lithosphere there would be no change on Earth.

about 170 million yearsAs a result, oceanic lithosphere is much younger than continental lithosphere: the oldest oceanic lithosphere is about 170 million years old, while parts of the continental lithosphere are billions of years old.

What are the components of the lithosphere?

The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.
