Question

1. What percentage of the incoming solar radiation is absorbed by gases in the atmosphere and clouds?

Select one:

a. 50

b. 30

c. 20

d. 5

2.

Two factors control the amount of solar radiation that a square meter receives at the outer edge of the atmosphere, and eventually Earth's surface. They are intensity and duration. Define these terms.

Select one:

a. Intensity is the concentration of time over that square meter. Duration is the length of time the Sun spends over that square meter.

b. Intensity is the concentration of energy over that square meter. Duration is the length of time the Sun spends over that square meter.

c. Intensity is the concentration of orange juice over that square meter. Duration is the length of time the Sun spends over that square meter.

d. Intensity is the concentration of energy over that square meter. Duration is the amount of energy the Sun expends over that square meter.

3.

The Sun's energy, or solar radiation, that strikes the outer edge of the Earth's atmosphere at any one place

Select one:

a. is more intense at the poles.

b. is not constant but varies with the seasons.

c. is constant and does not vary.

d. is controlled by the Sun god, Helios.

4.

The Earth absorbs long-wave radiation, while allowing the transmission of most of the short wavelengths. Essentially, what the Earth is doing is trapping heat. For this reason, the planet is warm enough to sustain human life. This process is called

Select one:

a. the greenhouse effect.

b. terrestrial radiation.

c. reflection.

d. the coriolis effect.

5.

Land and water absorb solar radiation unequally. Which would heat up and cool down more quickly, a pot full of dirt or a pot full of water? (given the same volume of each)

Select one:

a. water

b. dirt
