AMS SOL 6.6 part 2
| Question | Answer |
|---|---|
| Conduction | the transfer of heat that occurs when molecules touch and pass the heat along |
| Examples of Conduction | heat traveling down a match, burning feet on sand, food cooking in a frying pan |
| Convection | the transfer of heat by the flow of material causing a current to form |
| Examples of Convection | water boiling, ocean currents, heat from a vent spreading out in a room |
| Radiation | heat transfer in the form of rays or waves |
| Examples of radiation | rays of sunlight coming to Earth, heat waves coming off a fire |
| Polar Easterlies | wind that travels from east to west near the North and South poles |
| Westerlies | wind that travels west to east; crosses the United States |
| Trade Winds | Winds that cross the major oceans, helped early sailors to navigate |
| Doldrums | windless zone near the equator with daily rainfall |
| Coriolis Effect | the rotation of Earth causes wind to curve and creates ocean gyres |
| Global Winds | effect the entire planet, caused by the Coriolis Effect and uneven heating of Earth |
| Jet Stream | a narrow belt of strong winds traveling west to east in the upper Troposphere |
| gyres | rotating ocean current |
| gyre pollution problems | plastics end up in the oceans, some break down and are eaten by fish, some wash up on beaches, and many end up trapped in the gyre whirlpools |
| anemometer | measures wind speed |
| barometer | measures air pressure |
| occurs in low air pressure | stormy, cloudy weather |
| occurs in high air pressure | clear dry weather |
| compass | tells direction, red always points North |
| hygrometer | measures humidity |
| humidity | water vapor in the air |
| radar | shows precipitation on a weather map |
| rain guage | measures rain fall |
| satellite | can be used to view clouds from space in order to help predict weather |
| thermometer | measures temperature |
| weather balloon | carries instruments to measure weather conditions at high altitudes |
| wind vain | indicates the direction wind is coming from |
| cirrus | thin feathery clouds that indicate fair or changin weather |
| stratus | low blanket of clouds that covers the sky and usually indicates rain or snow |
| cumulus | fluffy white clouds |
| cumulonimbus | very tall dark storm clouds |
| rain | precipitation that occurs when the air temperature is above freezing |
| snow | occurs when water vapor changes directly to a solid |
| sleet | forms as rain falls through layers of freezing air on its way down |
| hail | pellets of ice that grow larger as they are blown back up in the clouds |
| condensation | water vapor changes to a liquid |
| dew point | the temperature at which condensation occurs |
| weather | the state of the atmosphere at a specific time and place |
| wind | air moving in a specific direction; caused by uneven heating |
