Weather Short Answer
| # | Answer |
|---|---|
| 1 | Weather is the condition of the air and sky at a certain place and time. |
| 2 | Temperature, wind, clouds, and precipitation can change the weather. |
| 3 | A thermometer measures temperature. |
| 4 | A rain gauge measures how much rain has fallen. |
| 5 | People check the forecast so they can plan for rain, heat, wind, or cold. |
| 6 | It is called precipitation. |
| 7 | Wind is moving air. |
| 8 | A windsock shows the direction the wind is blowing. |
| 9 | A cirrus cloud usually looks thin, wispy, and high in the sky. |
| 10 | A cumulus cloud is puffy and often looks like cotton balls. |
| 11 | A cumulonimbus cloud is dark and often brings heavy rain or storms. |
| 12 | Humidity measures how much water vapor is in the air. |
| 13 | Warm air is lighter than cool air, so it rises. |
| 14 | Wind moves heat away from our skin, so we feel cooler. |
| 15 | Evaporation is when liquid water changes into water vapor and goes into the air. |
| 16 | Condensation is when water vapor cools and changes into tiny water droplets. |
| 17 | Clouds form when water vapor cools and condenses into tiny droplets or ice crystals. |
| 18 | Weather is what the air is like now, while climate is the usual weather of a place over a long time. |
| 19 | Meteorologists use weather maps to study and predict weather patterns. |
| 20 | A barometer measures air pressure. |
| 21 | Air pressure is the force of air pushing on everything around it. |
| 22 | Air pressure usually drops before a storm. |
| 23 | Low pressure can help air rise, cool, and form clouds and precipitation. |
| 24 | A weather forecast is a prediction of what the weather may be like in the future. |
| 25 | Weather satellites show clouds and storm systems from above. |
| 26 | A drizzle is light rain, and a downpour is very heavy rain. |
| 27 | Frost is a thin layer of ice that forms when water vapor freezes on cold surfaces. |
| 28 | Snow stays frozen when the temperature is cold enough to keep it from melting. |
| 29 | Thunder is caused by lightning heating the air very quickly, which makes the air expand. |
| 30 | Lightning is caused by a buildup and release of electrical energy in a cloud or between clouds and the ground. |
| 31 | Lightning is dangerous because it carries a huge electrical charge and can start fires or hurt people. |
| 32 | You should go indoors or to a safe shelter right away. |
| 33 | A building with walls and a roof is a safe place during a thunderstorm. |
| 34 | They use several tools because each one measures a different part of the weather. |
| 35 | The type, size, and color of clouds can give clues about rain or storms. |
| 36 | A severe weather warning means dangerous weather is happening or about to happen soon. |
| 37 | A watch means dangerous weather may happen, and a warning means it is happening or likely very soon. |
| 38 | Different places get different amounts of rain because of temperature, wind, mountains, and ocean air. |
| 39 | Mountains can block moist air, causing more rain on one side and drier air on the other side. |
| 40 | The water cycle is the movement of water on Earth, and it connects to weather through evaporation, condensation, and precipitation. |
| 41 | Warm air can hold more water vapor because its molecules move faster and keep water vapor spread out. |
| 42 | Clouds look gray when they are thick and block more sunlight from passing through. |
| 43 | A front is where two air masses meet, and it can bring changes in temperature, wind, and precipitation. |
| 44 | An air mass is a large body of air with similar temperature and humidity. |
| 45 | A cold front can force warm air upward quickly, which can form clouds and storms. |
| 46 | Deserts are usually dry with little rain, while rainforests are usually warm and very wet. |
| 47 | Recording weather over many days helps scientists find patterns and make better predictions. |
| 48 | Weather data helps farmers decide when to plant, water, and protect crops. |
| 49 | A storm or rain may happen next because those signs often come before bad weather. |
| 50 | Water evaporates into the air, condenses into clouds, and then falls as precipitation when the droplets become heavy enough. |
