Weather
| Question | Answer |
|---|---|
| The condition of the Earth's atmosphere at a particular place and time. | weather |
| The average weather over a period of time. | Climate |
| The amount of water vapor in the air. | Humidity |
| An instrument used to measure relative humidity. It has two thermometers, wet bulb and a dry bulb | Sling psychrometer |
| An instrument used to measure wind speed in mph. | Anemometer |
| Used to measure precipitation | Rain guage |
| An instrument used to show the direction the wind is coming from. It can be seen as a rooster on top of a roof | Wind vane |
| An instrument that is used to measure barometric pressure/air pressure. | Barometer |
| Means bad weather. A capital L on a weather map is the symbol. | Low pressure system |
| Usually means good weather. A capital H on a weather map is the symbol. | High pressure system |
| The layer of the atmosphere where weather occurs. | Troposphere |
| The coldest layer | Mesosphere |
| The four major layers of the atmosphere from the Earth's surface to outer space. | Troposphere, stratosphere, mesosphere, and thermosphere. |
| A form of oxygen found in the stratosphere. | Ozone |
| The layer where the most water vapor is found. | Troposphere |
| This decreases the higher you go up in the atmosphere. | air pressure |
| The two most common gases | Nitrogen and oxygen |
| The most abundant gas. | Nitrogen |
| Meteors burn up here. | Mesosphere |
| The layer that has the greatest air pressure. | Troposphere |
| Any form of water droplets that fall from the sky. | Precipitation |
| This happens when water vapor changes to water droplets. | Condensation |
| Water flowing back towards sea level | Run-off |
| This is how plants contribute to the water cycle | Transpiration |
| Fluffy, cotton ball shaped with flat bottoms | Cumulus |
| Clouds that are made of ice crystals | Cirrus |
| Mean medium | Alto |
| The largest cloud | Cumulonimbus |
| Flat layered clouds | Stratus |
| A large body of air | Air mass |
| An air mass that forms over land | Continental |
| A warm air mass meeting a cold air mass causing periods of precipitation and warm temperatures | Warm front |
| A warm air mass and a cold air meeting. They don't move. May produce long periods of precipitation. | Stationary front |
| The symbol for a warm front. | A red semi circle |
| The symbol for a cold front. | A blue triangle |
| A warm air mass between two cold air masses. The symbol has red semi circle and blue triangles on the same side. | Occluded front |
| Rapid whirling,funneled shaped cloud | Tornado |
| A low pressure system that form over warm ocean water. | Hurricane |
| A weather tool used to see clouds. | Satellites |
| A weather tool used to see precipitation. | Radar |
| Heats up faster | Land |
| Cools down faster | Land |
| The trapping of gases in the atmosphere that helps keep Earth warm. | Greenhouse effect |
| The climate zone that we live in. | Mild/Temperate |
| Warm air rising and cool air sinking. This cycle continues. | Convection current |
| A global wind that blow from east to west in the tropical region. Traders used them | Trade winds |
| Winds that blow from west to east in the temperate region | Westerlies |
| Winds that blow northeast to west in the polar region moving cold polar air | Polar winds |
| A fast moving ribbon of air that moves from west to east. Located about six miles above the Earth. | Jet Stream |
| The curving of the winds due to the Earth rotating. | Coriolis Effect |
| The parts of the water cycle. | Evaporation, condensation, run off, groundwater, precipitation,and transpiration. |
| Lines on a weather map that connect places that have the same temperature. | Isotherms |
| Lines on a weather map that connect places that have the same air pressure. | Isobars |
| What nimbo/nimbus means | rain |
