Answer:
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.
- According to the theory of plate tectonics, the earth is broken into series of slabs.
- These slabs are called the lithosphere.
- The lithosphere is made up of part of the crust and upper mantle.
- This lithosphere gently moves over the weak asthenosphere below.
- The asthenosphere moves under influence of mantle convection.
