| Question | Answer |
|---|---|
| What is weather | the condition of Earth's atmosphere at a certain time and place |
| what is temperature | a measure of the average kinetic energy particles |
| what is thermal energy | total kinetic energy of particles |
| what is thermal expansion | the increase in volume that results from an increase in temperature |
| what is heat | energy that is transferred between objects that are at different temperatures |
| what is wind | the movement of air caused by differences in air pressure |
| what is the Coriolis effect | the apparent curving of the path of a moving object from an otherwise straight path due to the Earth's rotation |
| what is jetstream | narrow belts of high-speed winds that blow from west to east between 7 km and 16 km above Earth's surface |
| what is local wind | the movement of air over short distances |
| what is sea breeze | a cool breeze coming off an ocean or lake during the day |
| what is land breeze | air that flows from land to water during night |
| what is a mountain breeze | uneven heating results in an area of lower pressure near the mountain tops |
| what is Valley Breeze | pressure differences cause says Valley breezes |
| what are trade winds | the rotation of Earth cause Trade Winds to curve West they relied on by Sailors to guide them |
| what are westerlies | the rotation of Earth causes West relies to curve East and carry moist air over us producing rain and snow |
| what are polar easterlies | cold sinking air moving from the poles toward 60 degrees north 60 degrees south they also carry cold Arctic air and produce so |
| what are doldrums | when Trade Winds of both hemispheres and meet in a calm around the equator |
| what are horse latitudes | at about 30 degrees latitude in both hemispheres are stops moving and sinks |
| what is evaporation | when liquid changes into water vapor |
| what is condensation | the change of state from a gas to a liquid |
| what is precipitation | any form of water that falls to Earth from clouds |
| what is transpiration | Stomato are tiny holes that are found in some plant surfaces this release of water vapor into the air by plants is called transpiration |
| what is runoff | all of the water on land flows downhill because of gravity streams rivers and the water that flows over the land are types of runoff |
| what is humidity | the amount of water vapor in the air |
| what is relative humidity | the amount of water vapor in the air compared to the amount of water vapor needed to reach saturation |
| what is dew point | the temperature at which more condensation that evaporation occurs |
