Earth has the three main climax zones because of the differences in latitude and

latitude and longitude

Assuming that it is "Climate Zone" the answer could be - distribution of sunlight.

Explanation:

Climate zones are the regions of the earth with a distinct or different climate than one another. This climate change takes place in an east-west direction all around the earth. The climate zones normally appear to be curved or circular around the polar regions.

The major main climate zones are; polar, tropical and temperate climate zone that can be further divided into subtropical regions. The differences in these climate zones are because different latitude gets a different amount of sunlight and determines the climate for particular regions.

Thus, the correct answer is - Distribution of sunlight.
