1) The lowest layer of the atmospheric, containing about 75% of all the air in the atmosphere. It contains the air we breathe and is where weather, clouds, and air pollution are found. The temperature decreases as altitude decreases. a) troposphere b) stratosphere c) mesophere d) thermosphere e) exosphere f) ionosphere 2) The upper parts of the atmosphere where ions (charged atoms) are found. Radio waves bounce off the ionosphere. -spans from thermosphere through exosphere. a) Troposphere b) Mesophere c) Thermosphere d) Stratosphere e) Ionosphere f) exosphere 3) The atmospheric layer between the mesosphere and the exosphere where the molecules contain the most heat energy; the Northern and Southern lights, known as the auroras are found here. The ionosphere The temperature increases as altitude increases. a) Troposphere b) Mesophere c) Thermosphere d) Stratosphere e) Ionosphere f) exosphere 4) The upper parts of the atmosphere where ions (charged atoms) are found. Radio waves bounce off the ionosphere. -spans from thermosphere through exosphere. a) Troposphere b) Mesophere c) Thermosphere d) Stratosphere e) Ionosphere f) exosphere 5) The second layer from the Earth’s surface. It contains the ozone layer. The temperature increases as altitude increases due to the ozone layer’s absorption of ultraviolet rays from the sun. a) Troposphere b) Mesophere c) Thermosphere d) Stratosphere e) Ionosphere f) exosphere 6) The height above a specific point, as the surface of Earth or sea level. a) Level b) Pressure c) Altitude d) Layer 7) A region in which the atmospheric pressure is higher than in the surrounding areas; associated with relatively dry air and sunny weather;  a) high pressure system b) low pressure system c) cold front d) warm front 8) A region in which the atmospheric pressure is lower than in the surrounding areas; associated with relatively moist air and cloudy conditions a) high pressure system b) low pressure system c) cold front d) warm front 9) The boundary between an advancing mass of relatively warm air and a mass of colder air. a) high pressure system b) low pressure c) cold front d) warm front 10) The boundary between an advancing mass of relatively cold air and a mass of warmer air. a) high pressure system b) low pressure c) cold front d) warm front 11) a large body of air that is similar in temperature, humidity, and air pressure throughout. a) air pressure b) high pressure system c) air mass d) low pressure system 12) the force of air on a surface. a) barometric pressure b) wind pressure c) surface pressure d) air pressure 13) the layer of gases that surrounds Earth or another planet. a) Troposphere b) Mesophere c) Thermosphere d) Atmosphere e) Ionosphere f) stratosphere 14) Is formed when a cold front overtakes a warm front and in the process “cuts off” the warm from overcontact with the ground a) stationary front b) warm front c) occluded front d) cold front 15) the temperature to which air must be cooled to become saturated with water vapor, assuming constant air pressure and water content. a) dew point b) humidity c) 100 degrees d) 180 degrees e) Fog point 16) The concentration of water vapor present in the air. a) dew point b) humidity c) condensation d) evaporation e) sublimation f) transpiration 17) the energy contained within a system that is responsible for its temperature. a) specific heat capacity b) specific heat energy c) thermal energy
