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 |
