| geology | The study of the planet Earth. |
| constructive force | Shape the Earth by building up mountians and land masses. |
| destructive force | Change Earths surface by slowly wearing away mountians and other features. |
| seismic waves | One way to indirectly look inside the Earth. |
| pressure | The force pushing on an area or surface. |
| crust | The layer of rock that forms Earths skin. |
| basalt | Makes up most of the oceanic crust. |
| granite | Makes up most of the continental crust. |
| mantle | Layer of hot rock below the basalt and granite. |
| lithosphere | The uppermost part of the mantle and the crust. |
| asthenosphere | Earths layer that is somewhat soft and part of the mantle |
| outer core | Part of the core that is molten metal. |
| inner core | Part of the core that is a dense ball of solid. |
| radiation | The transfer of heat through empty space. |
| conduction | The direct transfer of heat in a solid material. |
| convection | Heat transfer involving the movement of fluids liquids and gasses. |
| density | Measure of how much mass is in a volume of a substance. |
| heat transfer | The movement of heat from a warmer object to a cooler object. |
| convection current | Occurs when a fluid is heated, becomes less dense and moves to the top allowing the cooler fluid to fall to the bottom. |
