| maritime | of, relating to, or bordering on the sea. |
| clouds | a large collection of very tiny droplets of water or ice crystals. |
| Condensation | the process by which water vapor (water in its gas form) turns into liquid |
| Cirrus Clouds | high feathery clouds |
| hygrometer | The instruments used to measure the humidity |
| Map | a drawing of all or part of Earth's surface |
| globe | a spherical model of Earth |
| Cumulonimbus (storm clouds) | large, tall clouds that are dark on the bottom, bring thunderstorms, have a fuzzy outline toward the upper part of the cloud and may have a flat top called an anvil |
| Cirrocumulus | high-altitude cloud form consisting of small white rounded masses usually in regular groupings. |
| Stratocumulus | condensed water droplets. |
| Cirrostratus | a fairly even high cloud layer that is darker than cirrus. |
| Nimbostratus (steady rain) | Nimbostratus clouds are low-hanging, dark gray clouds that block the sun completely. They make steady rain or snow, but not thunderstorms or lightning. They form at warm fronts from altostratus clouds that sink lower to the ground and get thicker. |

| air pressure | the weight of air molecules pressing down on the Earth |
| barometer | an instrument used to measure air pressure. |
| Low pressure | when warm air rises up to make clouds and rain. (Lousy) |
| High pressure | air molecules are held down resulting in clear, sunny days. |
| cold front | when the cold air mass takes over the warm air mass, causing it go up into the atmosphere. |
