The Theory of Plate Tectonics
Plate tectonics is a theory that describes the movements of Earth's lithosphere. There are 7 types of Plates. The Plates are...
1. African Plate 2. Antarctic Plate 3. Pacific Plate
4. South American Plate 5. North American Plate
6. AustrailiaPlate 7. Eurasia Plate
The Crust is broken into many pieces called Plates and the Plates float on the Mantle. The Plates move smoothly but sometimes, they crash together, and build up pressure. When they snap together, the Earthquake happens!
