The seasons are caused by the angle of Earth's axis.

Here's a step-by-step explanation:

1. The Earth's axis is tilted at an angle of about 23.5 degrees relative to its orbit around the Sun. This tilt is what causes the seasons.

2. During different times of the year, different parts of the Earth receive the Sun's rays more directly.

3. For example, during the summer, the part of the Earth experiencing summer is tilted towards the Sun. This means the Sun's rays hit that part of the Earth more directly, causing it to be warmer.

4. In contrast, during the winter, the part of the Earth experiencing winter is tilted away from the Sun. This means the Sun's rays hit that part of the Earth at a more oblique angle, causing it to be cooler.

5. So, it's not the Earth's distance from the Sun, the calendar, or the Sun's temperature that causes the seasons. It's the tilt of the Earth's axis.
