Answer 1

1.  the theory that Earth's outer shell is divided into several plates that glide over the mantle
2. I am not sure
3. Earth's mantle contained convection cells that dissipated radioactive heat and moved the crust at the surface
4.  supercontinent that existed during the late Paleozoic and early Mesozoic eras.
5.  the theory that the outer rigid layer of the earth (the lithosphere) is divided into a couple of dozen "plates" that move around across the earth's surface relative to each other, like slabs of ice on a lake.
6. Africa and South America.
7. I am not sure
8. a small area or region with a relatively hot temperature in comparison to its surroundings.
9. As the plate moves over a fixed spot deeper in the Earth where magma (molten lava) forms, a new volcano can punch through this plate and create an island. The Hawaiian Islands are believed to be formed from one such 'hot spot'.
