What this covers

The primary source of energy driving Earth's climate system is:
Gases like carbon dioxide and methane that trap heat in Earth's atmosphere are called:
The greenhouse effect refers to the process where:
Most of the incoming solar energy that reaches Earth is eventually:
Of the solar energy arriving at the top of Earth's atmosphere, about 30% is reflected straight back to space by clouds, ice and the atmosphere. Of the energy that is not reflected, an amount equal to about 23% of the original arriving energy is absorbed by the atmosphere and clouds before it reaches the ground. What percentage of the arriving solar energy is absorbed by Earth's surface?
Fresh snow reflects most of the sunlight that hits it, while dark soil reflects very little. The measure of how reflective a surface is, is called its:
Why does each square metre of ground at the equator receive more solar energy than each square metre near the poles?
Earth's average surface temperature is about 15 degrees Celsius. Without the natural greenhouse effect it would be about -18 degrees Celsius. By how many Celsius degrees does the natural greenhouse effect warm Earth's surface?
Use the table. Where does most of the incoming solar energy end up?
