Name: _________________ Unit 8: Earth’s Oceans and Atmosphere Term Definition weather the state of the atmosphere with respect to wind, temperature, cloudiness, moisture, pressure, etc. climate the weather conditions prevailing in an area in general or over a long period water cycle the process by which water is circulated between the earth’s ocean, land, and atmosphere equilibrium a state of homeostasis precipitation process by which water falls to the earth as either: rain, snow, sleet, or hail. condensation the process in which water vapor is changed into a liquid evaporation the process when liquid water changes into water vapor (occurs over bodies of water) transpiration the process by which plants release water vapor from their leaves run off when rain is not absorbed into the ground, it travels down hills to flow into streams and rivers air temperature The average kinetic energy of molecules. humidity amount of water vapor in the air. air pressure air exerting pressure on the air below it. jet stream 10km above the surface, winds blow from west to east easterlies wind coming from the east westerlies wind coming from the west trade winds a wind blowing steadily toward the equator (from the northeast in the northern hemisphere and from the southeast in the southern hemisphere doldrums area around the equator where the wind completely dies out horse latitudes 30 degrees N and S of equator calm winds occurring in both the northern and southern hemispheres between the trade winds and the westerlies. coriolis effect the deflection of air masses resulting from Earth’s eastward rotation atmosphere the gas surrounding the earth air mass a large body of air that has uniform temperature, humidity, and air pressure front a boundary between two different air masses weather instruments types of instruments that help read weather, for example, anemometer, barometer, psychrometer, and thermometer conduction transfer of energy by touching convection transfer of energy by the movement of particles radiation transfer of energy through electromagnetic waves land breeze wind that blows from the land to the sea sea breeze wind that blows from the sea to the land upwelling a rising of sea water, magma, or liquid isobars lines that connect all places with the same pressure values isotherms lines that connect all places with equal or same temperature values meteorologist person who studies weather and Earth’s atmosphere Fujita scale scale to rate tornado intensity (also known as the F-scale)
