As you can see in Figure 3.3.1, during the summer months in the Northern Hemisphere, the North Pole is tipped towards the sun so the hemisphere receives more direct solar rays and is warmer. At the same time, the Southern Hemisphere receives fewer direct rays, becomes cooler, and experiences winter. This is why when it is summer in Canada, it is winter in Australia.

In Figure 3.2.2 the South Pole is tipped toward the sun. Do you know what season the people in South America experience when the earth is tipped this way? What season is it in the United States? If you said it is summer in South America and winter in the US, then you are right.
