Riley lives near a polar zone, where it is cold. He visits his friend Thalia, who lives in a tropical zone, where it is warm all year. They live at similar elevations, and neither lives in a coastal area.

The difference in the climate is because of the latitude.

Explanation:

The climate of a particular region differs from that of another region because of many reasons. One of the reasons is the difference in the latitude of the regions. The difference is in the amount of solar radiation received by the different regions. In the polar region, the temperature is low and it is cold there. While, in the tropical regions, the temperature is high and therefore it is warm in these regions.
