extremely cold and dry a atmospheric pressure increases with increasing altitude b atmospheric pressure remains constant with increasing altitude c atmospheric pressure decreases with increasing altitude d atmospheric pressure first increases then decreases with increasing altitude Answer c Atmospheric pressure decreases with increasing height altitude At the 500 mb level the amount of oxygen inhaled in a single breath is of that inhaled at sea level a about the same b about one quarter c about one half d about three quarters Answer c about one half Clouds often form in the a rising air in the center of a low pressure area b rising air in the center of a high pressure area c sinking air in the center of a low pressure area d sinking air in the center of a high pressure area Answer a Rising air in the center of a low pressure area Condensation is more likely to occur Answer When the air cools Generally weather in the middle latitudes tends to move from to a west east b south north c east west d north south Answer a West East If you were to take a breath of pure oxygen from a tank you d be getting about the amount of oxygen that you d get by taking a normal breath of our atmosphere a one fifth b half c twice d three times e five times Answer e Five times In a temperature inversion a air temperature increases with increasing height b air temperature decreases with increasing height c air temperature remains constant with increasing height d it is warmer at night than during the day Answer a air temperature increases with increasing height In a volume of air near the earth s surface occupies 78 and nearly 21 a nitrogen oxygen b hydrogen oxygen c oxygen hydrogen d nitrogen water vapor e hydrogen helium Answer Nitrogen Oxygen In the atmosphere tiny solid or liquid suspended particles of various compositions are called a aerosols b carcinogens c greenhouse gases d fog Answer Aerosols In the middle latitudes of the Northern Hemisphere surface winds tend to blow and around an area of low surface pressure a clockwise inward b clockwise outward c counterclockwise inward d counterclockwise outward Answer c Counterclockwise Inward In the middle latitudes of the Northern Hemisphere surface winds ten to blow and around an area of high pressure a clockwise inward b clockwise outward c counterclockwise inward d counterclockwise outward Answer Clockwise Outward In the stratosphere the air temperature normally a decreases with increasing height b increases with increasing height c both increases and decreases depending on the season d cannot be measured Answer b Increases with increasing height Meteorology is the study of a landforms b the oceans c the atmosphere and its phenomena d outer space e extraterrestrial meteoroids that enter the atmosphere Answer c The atmosphere and its phenomena Most of the ionosphere is found in what atmospheric layer a troposphere b stratosphere c mesosphere d thermosphere Answer d Thermosphere Much of Tibet lies at altitudes over 18 000 feet where the pressure is about 500 mb At such altitudes the Tibetans are above roughly a 10 of the air molecules in the atmosphere b 25 of the air molecules in the atmosphere c 50 of the air molecules in the atmosphere d 75 of the air molecules in the atmosphere Answer 50 of the air molecules in the atmospher On a weather map sharp changes in temperature humidity and wind direction are marked by a a front b an anticyclone c a ridge d blowing dust Answer A front Ozone in the stratosphere a Protects life from harmful ultraviolet radiation b Absorbs UV radiation c warms the stratosphere causing a temperature inversion d all of the above Answer d all of the above Since the turn of this century CO2 in the atmosphere has a disappeared entirely b been decreasing in concentration c remained at about the same concentration from year to year d been increasing in concentration Answer Been increasing in concentration The amount of force exerted over an area of surface is called a density b weight c temperature d pressure Answer Pressure The atmospheric layer in which we live is called the a troposphere b stratosphere c thermosphere d ionosphere e exosphere Answer Troposphere The difference in altitude i e the thickness is greatest in the layer bounded by a 1 mb and 10 mb b 101 mb and 110 mb c 1001 mb and 1010 mb d impossible to determine Answer a 1mb and 10mb The earth s atmosphere is divided into layers based on the vertical profile of a air temperature b air pressure c air density d wind speed Answer Air temperature The electrified region of the upper atmosphere is called the a thermosphere b mesosphere c stratosphere d ionosphere e troposphere Answer d Ionosphere think ions The gas responsible for the greenhouse effect on Venus is a carbon dioxide CO2 b oxygen O2 c ozone O3 d nitrogen N2 e water vapor H2O Answer Carbon Dioxide CO2 The gas that absorbs most of the harmful ultraviolet radiation in the stratosphere is a water vapor b nitrous oxide c carbon dioxide d ozone Answer d Ozone O3 The gas that shows the most variation from place to place and from time to time in the lower atmosphere is which of the following a ozone O3 b carbon dioxide CO2 c water vapor H2O d methane CH4 e argon Ar Answer c water vapor H2O The greenhouse gas that has been increasing in concentration at least partly due to deforestation is a carbon dioxide CO2 b chlorofluorocarbons CFCs c water vapor H2O d ozone O3 Answer a Carbon Dioxide CO2 The hottest atmospheric layer is the a stratosphere b mesosphere c thermosphere d troposphere Answer c Thermosphere think thermometer The instrument that measures temperature pressure and humidity at various altitudes in the atmosphere is the a aneroid
