The Earth is tilted on its axis at an angle of approximately 23.5 degrees. This tilt is the reason we have seasons.
Here's a simplified explanation:
* The Earth's axis is an imaginary line running through the North and South Poles.
* This axis is tilted, not straight up and down.
* As the Earth orbits the Sun, the tilt causes different parts of the Earth to receive more or less direct sunlight throughout the year.
* This difference in sunlight leads to the seasons we experience.
