- Continental plates
- Oceanic plates
<h3>The theory of plate tectonics.</h3>
The theory of plate tectonics states that the solid outer crust of planet Earth (lithosphere) is typically divided into enormous (massive) slabs of solid rock (plates) that move over the asthenosphere, including the upper portion of the mantle.
<h3>The uses of the theory of plate tectonics.</h3>
- It can be used to explain the presence of magnetic anomalies on the ocean floor.
- It can be used to explain the geographical distribution of earthquakes and volcanoes.
- It can be used to explain the presence of glacial deposits in tropical areas.
- It can be used to explain the origin of mountains.
