Questions:

  1. The tropics receive more heat from the sun than is radiated away from the tropics, and polar regions radiate more than they receive. Describe how the heat gets from the tropics to the poles.
  2. What percentage of sunshine reaching the surface of the Earth is reflected back to space? List three physical features (either in the atmosphere or on Earth) that reflect back this sunshine.
  3. Define the term albedo. What is 0 percent albedo? What is 100 percent albedo?
  4. Use your understanding of what happens to gases as they rise to explain why the air temperature 10,000 ft above the earth is cooler than the air temperature 10 ft above the ground.
  5. The mountain desert effect occurs when deserts or dry lands form on the leeward side of mountain ranges. Why does this occur? Explain in terms of wind currents, changes in air temperature, and precipitation.
  6. This is a three part question: 1. Ocean waters at the poles sink for two reasons--what are they? 2. Describe two mechanisms that make the ocean saltier? 3. Describe three ways in which the ocean is replenished with freshwater.
  7. Though northern Europe (Scandinavian countries, etc.) is situated near the same latitude as Hudson Bay, northern Europe remains free of ice and is habitable. What keeps this region from being covered in ice and snow much of the year, like the Hudson Bay and the Arctic Circle? Explain in terms of wind, ocean currents, and solar radiation. Be as specific as possible.
