The Coriolis effect ________.
A. results in ice and dark at the poles in winter B. is caused by earth's rotational forces C. keeps Earth from spinning too fast D. is caused by the moon E. keeps the wind circulating at constant speed around the planet |

Air near Earth's surface tends to be ________.
A.cooler and drier; it rises when it is displaced by sinking warm air B. cooler and wetter; then it rises, is warmed by the sun, and sinks again C. warmer and wetter; then it rises, expanding and cooling D. warmer and drier; then it rises, condensing and gathering moisture E. warmer; it rises as it is displaced by Coriolis forces |
C. warmer and wetter; then it rises, expanding and cooling

The reason that temperature increases with altitude through most of the stratosphere is ________.
A. sunlight is more intense in the stratosphere B. jet stream winds produce frictional heat C. water vapor levels are high and store heat D. heat is released by absorption of UV radiation by oxygen and ozone E. greenhouse gases warm the air |
D. heat is released by absorption of UV radiation by oxygen and ozone

One key to the puzzle of Los Angeles smog is the fact that _______
A.the Hadley cell for that area drops cool air, and pollution, right over Los Angeles B. the offshore breezes carry inland pollution to coastal Los Angeles C.there are so many rainy days, increasing the acidic deposition D. incoming tides in the harbor push air pollution ahead of them E. Los Angeles and its suburbs are all ringed by mountains |
E. Los Angeles and its suburbs are all ringed by mountains
|
|
|
The Los Angeles smog problem is made much worse by ________.
A.the high cloud levels, which deplete the local ozone layer B. the convection cells, which bring pollutants from other cities C. nearby mountains and the warm sunshine, which cause inversion layers D. the foggy climate, which leads to acidic deposition E. the onshore breezes, which prevent pollution from dispersing |
C. nearby mountains and the warm sunshine, which cause inversion layers
|
|
|
Natural sources of air pollution come from ________.
A. birds B. internal combustion engines C. soil dust and volcanic dust D. coal-fired electrical plants E. evaporation of solvents |
C. soil dust and volcanic dust
