True or false

True

Explanation:

The theory of plate tectonics was borne out of the theories of seafloor spreading and continental drift. This encompassing theory provided a succinct explanation for why plates moves and the mechanisms that drives them.

This lithosphere gently moves over the weak asthenosphere below. The asthenosphere moves under influence of mantle convection.
