What Causes the ‘Change’ of Seasons?

Imagine Earth is like a spinning top, and it takes about 365 days to go all the way around the Sun. But here's the fun part: Earth isn't standing straight up, it’s tilted! This tilt means that different parts of Earth get more sunlight at different times of the year. When your half of Earth leans toward the Sun, you have summer; when it leans away, you have winter. It's like having a sunny side and a shady side, depending on where you are and when you're there!

Examples

  1. A child in the Northern Hemisphere plays outside all day in summer because their part of Earth is leaning toward the Sun.
  2. During winter, a snowman in the Southern Hemisphere melts quickly when it's spring there because that hemisphere is now tilted toward the Sun.
  3. In some places like near the equator, people don’t feel like they're having seasons at all because both hemispheres get about the same amount of sunlight year-round.
