Earth's Seasons

The earth's seasons, spring, summer, fall and winter, are all different temperatures because of the way the earth is tilted and how the sunlight shines on it.

When the top of the earth (where North America is) is tilted at the sun, that's when it is summer, the hottest time of the year.

When the top of the earth is tilted away from the sun, that's winter, the coldest time of the year.
