1

Aurora

Light emitted by atoms and molecules in the upper atmosphere and is a result of magnetic disturbance caused by solar wind

2

Convection

Rising and sinking motions in a liquid or gas that carry heat upward through the material

3

Coriolis Effect

Makes storms on Earth spin, generates large-scale wind systems, and creates cloud belts on many of the planets

4

Crust

The rigid surface of a planet, moon, or other solid body
