Which of the following helps to explain why even though northern latitudes experience 24 hours of sunlight on June 22, they are not warmer than latitudes further south?
all of the above, 1: solar energy is spread over a larger area in northern latitudes, 2: some of the sun's energy is reflected by snow and ice in the northern latitudes, 3: increased cloud cover reflects solar energy in the northern latitudes, 4: solar energy is used to melt frozen soil in the northern latitudes
Th earth's radiation is often referred to as ____ radiation, while the sun's radiation is often referred to as ______ radiation.
The albedo of the earth's surface is only about 4%, yet the combined albedo of the earth and the atmosphere is about 30%. Which set of conditions below best explains why this is so?
high albedo of clouds, low albedo of water
On the average, about what percentage of the solar energy that strikes the outer atmosphere eventually reaches the earth's surface?
