Weather Final Exam
terms to study for weather and water cycle final exam 11/18
| Question | Answer |
|---|---|
| In what direction do winds in the US usually move? | usually winds move from west to east |
| How do mountains effect weather? | temperature in mountainous areas tend to be colder (lower) than those in flat areas |
| This instrument measures air pressure | barometer |
| This instrument measures the amount of rain that falls | rain gauge |
| The amount of water vapor in the air | humidity |
| When a warm air mass and a cold air mass meet and do not move for an extended period of time | stationary front |
| A cold air mass moves under a warm mass and causes a short, intense precipitation | cold front |
| Forms when warm air bumps with colder air | warm front |
| An instrument that measures wind speed | anemometer |
| An air mass that forms over dry areas like deserts. | dry air mass |
| An air mass that forms over oceans. | wet air mass |
| The weight of air in an area. | air pressure |
| This pressure system brings warmer temperatures and more moisture and clouds/precipitation. | low pressure |
| This pressure system brings cooler temperatures and less moisture, fair weather. | high pressure |
| This is a scientist who studies and forecasts the weather and climate patterns. | meteorologist |
| This ocean current from the south causes Massachusetts to have warmer temperatures near the coast. | The Gulf Stream |
| This is the cause of wind. | The land and ocean heat unevenly, causing different air pressures. This makes air move (wind). |
| A large body of air that has the same temperature and amount of moisture (humidity) | air mass |
| Forms over cold land or cool oceans. | Cold air mass. |
| Forms over hot land or warm oceans. | Warm air mass. |
| Water that has soaked into the ground or has collected in a reservoir. | groundwater |
| This is the state of the atmosphere at a certain place or time. | weather |
| This is the average temperature and humidity of an area over a long period of time. | climate |
| This is formed during condensation and is made up of billions of tiny water droplets or ice crystals. | clouds |
| This is the measure of how warm or cold something is. | temperature |
| This instrument measures wind direction | wind vane |
| This instrument uses radar to measure precipitation and wind. | Doppler |
| This is the process in which water moves through the ground to the air and back to earth again. | water cycle |
| Water that falls to the ground from the clouds. | precipitation |
| The four types of precipitation | rain, snow, sleet or hail |
| The process of cloud formation; water vapor is cooled and the gas becomes a liquid. | condensation |
| The process by which water is heated and changes to water vapor. | evaporation |
| Water flowing over the Earth's surfaces into the lakes, rivers, and oceans. | Runoff |
| This is the process during which ice evaporates without melting first. | Sublimation |
| This is the process during which water evaporates from the leaves of plants during photosynthesis. | transpiration |
