Weather Challenge Practice
| # | Answer |
|---|---|
| 1 | Weather is the condition of the atmosphere at a place and time. |
| 2 | Nitrogen. |
| 3 | Oxygen. |
| 4 | Water in the gas state. |
| 5 | Evaporation. |
| 6 | Condensation. |
| 7 | Tiny water droplets and/or ice crystals. |
| 8 | It cools as it rises. |
| 9 | Cool air can hold less water vapor, so the vapor condenses into tiny droplets. |
| 10 | The amount of water vapor in the air. |
| 11 | Muggy or sticky air. |
| 12 | Water that falls from clouds as rain, snow, sleet, or hail. |
| 13 | Rain. |
| 14 | The continuous movement of water between Earth’s surface, the atmosphere, and back again. |
| 15 | Evaporation, condensation, precipitation, or collection. |
| 16 | A thermometer. |
| 17 | A barometer. |
| 18 | The force exerted by air on a surface. |
| 19 | Falling pressure often means unsettled or stormy weather is coming, while rising pressure often means fair weather. |
| 20 | A boundary where two different air masses meet. |
| 21 | A large body of air with similar temperature and humidity. |
| 22 | Cold air has less energy, so it cannot keep as much water vapor in the air. |
| 23 | Higher temperature usually makes evaporation happen faster. |
| 24 | They often contain many water droplets, which can mean precipitation is forming. |
| 25 | Water evaporates into the air, condenses into clouds when air cools, and then falls as precipitation, changing the weather. |
