| Wind | The horizontal movement of air from an area of high pressure to an area of lower pressure. |
| Local Winds | Winds that blow over short distances. |
| Sea Breeze | The flow of air from an ocean or lake to the land. |
| Land Breeze | The flow of air from land to a body of water. |
| Global Wind | Winds that blow steadily from specific directions over long distances. |
| Coriolis Effect | Earth's rotation makes winds in the Northern Hemisphere curve to the right and winds in the Southern Hemisphere curve to the left. |
| Horse Latitudes | 30 N and S latitude, calm to no winds. |
| Doldrums | located at the equator, calm to no wind. |
| Trade Winds | Winds that blow from 30 N latitude or 30 S latitude toward the equator, in a westerly direction. |
| Prevailing Westerlies | Winds that blow from 30 N or S latitude or 60 N or S latitude, in an easterly direction. |
| Polar Easterlies | Winds that blow from the poles toward 60 N or S latitude, in a westerly direction. |
| Jet Streams | Bands of high-speed winds about 10 km above Earth's surface. |
| Hydrosphere | Earth's water environments; oceans, lakes and rivers. |
| Evaporation | The process by which a liquid becomes a gas; water to water vapor. |
| Condensation | The process by which a gas becomes a liquid or solid; water vapor to water or ice crystals. |
| Precipitation | Any form of water that falls from the clouds and reaches Earth's surface. |
| Humidity | A measure of the amount of water vapor in the air. |
| Dew Point | The temperature at which condensation begins. |
