Exam III GEO 107 Multiple Choice Identify the choice that best completes the statement or answers the question. ____ 1. Why does a mass of air get cooler as it rises over a mountain? a. The air gets cooler because it loses heat to its surrounding cool air. b. The air gets cooler because nearby ice and snow are cold. c. The air gets cooler because the dry air at high elevations conducts heat away easily. d. Air with a certain amount of heat expands as it rises so that heat is distributed through a larger volume. e. The air gets cooler because there is more air pressure at the top of the mountain. ____ 2. An example of anthropogenic source of greenhouse gas is a. Volcanoes b. lightening storms c. burning of fossil fuels d. heating of the upper atmosphere e. Earthquakes ____ 3. Why are storms found at both warm fronts and cold fronts? a. In both cases, the warm, more-humid air rises rapidly over cold air, cooling, condensing, and raining. b. Where a warm front collides with a cold front, the friction between them generates heat and storms. c. In both cases, the northward-moving front goes to the right, so the storm cell formed turns counterclockwise. d. Warm fronts concentrate static positive charges; cold air concentrates negative charges. They storm where the two collide. e. Warm and cold airs do not mix easily because of their different densities, so the turbulence causes storms. ____ 4. In the Greenhouse effect a. Short wavelength radiation is blocked by greenhouse gases b. long wavelength radiation is blocked by greenhouse gases c. the albedo is reduced through increaseed growth of forests d. the Milankovich cycles spin out of control e. the world freezes over if greenhouse gases get to high ____ 5.

The main reason for warmer summers in middle latitudes is due to what? a. The Earth is closer to the sun in summer. b. The sun is higher in the sky, and we receive more direct solar radiation. c. Ocean currents transport heat from the tropics to middle latitudes. d. Plants in the mid-latitudes enhance the greenhouse effect. e. Global warming causes this. ____ 9. Of the following the Milankovich cycles involve a. Eccentricity of the Earth b. The tilt of the Earth c. The wobble of the Earth d. a,b and c e. none of the above ____ 10.
