Exam 2: The Earths Global Energy Balance

The greenhouse effect is caused by counter-radiation of longwave energy from gases like carbon dioxide and water vapor.

Hot objects emit ______ energy than cold objects, and it is of _______ wavelengths.

The equatorial region receives lower annual isolation levels with the earth's axis tilted than they would if the axis were perpendicular to the plane of the ecliptic.

Taken together, nitrogen and oxygen account for about 99% of the gases in our atmosphere.

Electromagnetic energy in the range from 0.2 to 3 micrometers is called shortwave radiation.

The proportion of solar radiation that is reflected by an object is that object's ________.

Counterradiation is the longwave energy that the earth radiates in to space to balance the shortwave energy it receives from the sun.
