|---|
| inner core | inner-most layer of Earth; pressure keeps this layer a solid; iron and nickel |
| outer core | heat makes this layer a liquid; molten metal; responsible for the Earth's magnetic field |
| asthenoshpere | The "softer" layer of the mantle |
| lithosphere | the "rock hard" layer of the mantle that also includes the crust |
| oceanic crust | outer-most layer that can be as little as 5 km think; consists mainly of basalt |
| continental crust | outer-most layer that can be up to 70 km think; consists mainly of granite |
| heat transfer | the movement of heat from warmer things to cooler things |
| radiation | the movement of heat through SPACE |
| conduction | the movement of heat through one object, or from one object to another when they TOUCH |
| convection | the movement of heat through currents in a LIQUID or GAS; depends on density, heating, cooling, and gravity |
| lower mantle | the deepest and hottest of the layers of the mantle; closest to the core |
| heat from the sun warming your face | radiation |
| heat from a fire warming your hands | radiation |
| touching a hot pot | conduction |
| heat from holding someone's warm hand | conduction |
| heat from a radiator | radiation |
| heat from a hot pot burns your hand | conduction |
| soup in a pot on a stove burner | convection |
| the rock in the mantle moving because of the heat from the core | convection |
