Why we have day, night and seasons
Age 10 · Astronomy
The Earth spins around once every day, so each place turns toward the Sun and then away from it. The Earth also travels around the Sun in a year with its axis tilted, which changes the seasons.

In the picture
- The sunlit side of the Earth: it is daytime there
- The shadow side of the Earth: it is night there
- The tilted axis: sometimes the north leans toward the Sun, sometimes away
- The orbit: one trip around the Sun takes a year
Examples
- The Sun seems to rise in the morning because your side of the Earth is turning into the light.
- In summer the days are long and warm because your part of the Earth leans toward the Sun.
Key takeaways
- Spinning once a day gives day and night.
- Orbiting the Sun with a tilted axis gives the seasons.
