| Describes air pressure? | Is the measure of forces with which air molecules push on the surface. |
| What happens to air pressure as altitude increases? | Air pressure decreases |
| Describe jet streams? | Are narrow belts of high-speed winds that blows in the upper troposphere and lower stratosphere. |
| What is the greenhouse effect? | Is the process by which gases in the atmosphere, such as water vapor and carbon dioxide, absorb thermal energy and radiate it. back to earth. |
