Layers of the Earth

3. the thin and solid outermost layer of Earth above the mantle
6. the movement of matter due to differences in density that are caused by temperature variations; can result in the transfer of energy in heat
8. the solid, outer layer of Earth that consists of the crust and the rigid upper part of the mantle
9. the series of processes in which rock forms, changes from one type to another, is destroyed, and forms again by geologic processes
10. the central part if Earth below the mantle
11. the solid, plastic layer of the mantle beneath the lithosphere; made of the mantle rock that flows very slowly, which allows tectonic plates to move on top of it.

1. the layer of rock between the earth's crust and core.
2. the strong, lower part of the mantle between the asthenosphere and the outer core
4. a naturally formed, inorganic solid with a crystalline structure
5. the innermost geologic layer of the planet Earth
7. the fluid layer about 2400 kilometers thick composed of iron and nickel that lies above the inner core.
