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
