Lithosphere

Front

The age of the sea floor increases with increasing distance from a mid-ocean ridge.

Back

This principle explains how new oceanic crust is formed at mid-ocean ridges and older crust is pushed away.

What feature is created by a divergent plate boundary?

Back

Mid-ocean ridges and new seafloor.

Front

What is the asthenosphere?

Back

A semi-fluid layer of the mantle beneath the lithosphere that allows for the movement of tectonic plates.
