Why do we have seasons on Earth?

Explanation

The common misconception is that .Earth revolves around the Sun, so when the Earth is very far away, it is winter and when the Earth is nearer, it is summer.. Actually, the seasons in the Earth arise due to the rotation of Earth around the Sun with `23.5^@` tilt. Due to this `23.5^@` tilt, when the northern part of Earth is farther to the Sun, the southern part is nearer to the Sun. So when it is summer in the northern. hemisphere, the southern hemisphere experience winter.
