Factors That Affect Climate
The main factor that shapes our climate is solar energy that arrives as sunlight. Sunlight strikes different parts of Earth’s surface throughout the year because the Earth revolves on a tilted axis. Scientists have divided the Earth's surface into three main climate zones: polar, temperate, and tropical.

Label Earth’s main climate zones as temperate, tropical, or polar. You will use some terms more than once.
Answer the questions.
1. Which climate zone receives the most direct sunlight year-round? 	
	
2. Why are the polar zones colder than the other zones?
