~Hello everybody! Today, I'm going to explain why Earth has 4 seasons. (THE ANIMATION IS DESIGNED FOR THE NORTHERN HEMISPHERE) Let's get started! -Why do we have seasons? Summer, winter, spring, and fall are caused by Earth, tilted on its axis, revolving around the sun. -How does summer and winter happen? Summer happens in the hemisphere tilted towards the sun. Winter happens in the hemisphere tilted away from the sun! -Why do seasons change? When Earth is traveling around the sun, the hemisphere tilted towards the sun changes, causing seasons! I hope this helped you learn mores about Earth AND the seasons!
