Term
Define asthenosphere
Definition
the layer of the mantel that is made of very slow flowing slid rock below the lithosphere
Term
Define continental drift
Definition
the idea that a single large landmass broke up into smaller landmasses to form the continents, which then drifted to their present location
Term
