1) Closest layer to the surface which contains 90% of atmospheric gases is known as a) troposphere b) stratosphere c) exosphere d) mesosphere 2) The second layer of atmosphere from the Earth that contains ozone is called a) stratosphere b) troposphere c) mesosphere d) exosphere 3) Which layer of the atmosphere contains ozone? a) 1 b) 2 c) 3 d) 4 e) 5 4) Anything that moves over Earth's surface tends to turn a little rather than move in a straight line, which is called a) Corilois Effect b) El Nino c) Tradewinds d) Pressure systems 5) Wind is caused by a) Coriolis Effect b) wave energy c) movement of water molecules d) movement of molecules in the air 6) This type of system occurs when warmer air and water vapor rises from the surface near the equator, creating clouds and wet weather a) Coriolis Effect b) High pressure c) Low pressure d) La Nina 7) This type of system occurs when cooler air sinks toward the surface near the equator, creating dry weather with no precipitation a) Coriolis Effect b) El Nino c) Low pressure d) High pressure 8) These winds which blow from northeast or southeast at the equator are very important in propagating heat transport, propelling the global conveyor belt. a) Trade winds b) Polar easterlies c) Westerlies d) El Nino 9) This is the instrument used to measure air pressure a) Oxygen meter b) Barometer c) Thermometer d) Kilometer 10) Replacing the rising air warm air with cooler air, and creates two layers of horizontal winds moving in opposite directions, is called a a) Cyclone b) Hurricane c) Tornado d) Convection cell 11) When the trade winds slow down, a loss of upwelling occurs near the equator causing an unseasonal warming of oceanic water and severe weather and flooding. This is known as  a) La Nina b) El Nino c) Genetic drift d) Cyclonic storms 12) When the trade winds become stronger, larger amounts of upwelling occur near the equator causing an unseasonal cooling of oceanic water and results in drier weather and drought in some places. This is known as a) Cyclonic storms b) El Nino c) Cold front d) La Nina 13) The sudden change in water temperature over interval depths in the ocean are called a) Thermoclines b) Halophiles c) Thermal vents d) Stratosphere 14) The ocean has three layers due to changes in the water a) density, salinity, and temperature b) convection c) global conveyor belt d) tradewinds 15) The three ocean layers are a) surface b) intermediate c) bottom/deep d) salty 16) When surface water sinks due to increased density and mixes with deeper water, this is known as a) overturn b) upwelling c) downwelling d) upturn 17) Greenhouse gases work to trap heat within the atmosphere, maintaining Earth's temperature. Select all of the greenhouse gases below a) carbon dioxide b) methane c) nitrogen d) nitrous oxide e) water vapor f) carbon monoxide 18) Patterns of winds and surface currents cannot be understood without accounting for a) Global conveyor belt b) Coriolis Effect c) El Nino d) ENSO 19) These are rotating storms that are generated over warm waters of the tropics and that occur over much shorter time spans than ENSO (El Nino) a) Tornados b) Cyclonic storms c) La Nina d) El Nino 20) All are characterized by heavy rain, strong winds, and an eye in the middle of the storm. a) Cyclone b) Hurricane c) Tornado d) Typhoon 21) In tropical areas, warm air cools with altitude and condenses into rain and clouds, and the condensation releases great amounts of energy, which is converted into a) rain b) heat c) strong winds d) strong currents 22) Sustained winds classify cyclonic storms into 5 different categories based on this scale a) Saffir-Simpson hurricane scale (SSHS) b) OJ-Simpson hurricane scale (OSHS) c) National Oceanic and Atmospheric Association (NOAA) d) Strong-Winds hurricane scale (SWHS) 23) The rotation of cyclones is due to a) ENSO b) El Nino c) Coriolis Effect d) tradewinds 24) Cyclones rotate counter clockwise in the a) northern hemisphere b) southern hemisphere c) equator d) Pacific e) Atlantic 25) Cyclones rotate clockwise in the a) northern hemisphere b) southern hemisphere c) equator d) Pacific e) Atlantic 26) According to the Saffir-Simpson hurricane wind scale, a category 5 storm would have sustained winds that meet or exceed a) 95 mph b) 110 mph c) 129 mph d) 156 mph e) 157 mph
