Fact 1: Unequal heating of Earth 's surface by the Sun causes global wind patterns.

Fact 2: Unequal absorption of radiation causes unequal heating of the earth's surface.

Given the two facts above, answer the question "Unequal absorption of radiation on the earth's surface causes what?" with the following options: 
- electromagnetic energy
 - global travel patterns
 - fissures of hot, acidic water
 - Temperature
 - global migration patterns
 - global rain patterns
 - global wind patterns
 - Greenhouse gasses
