1. The Earth's Tilt:
* Our planet is tilted on its axis at approximately 23.5 degrees. This tilt is not perfectly straight up and down like a spinning top. Instead, it's tilted over.
* This tilt means that different parts of the Earth receive varying amounts of direct sunlight throughout the year.
2. The Earth's Orbit:
* The Earth orbits the Sun in an elliptical path. This means that the Earth is not always the same distance from the Sun.
* When the Earth is closer to the Sun, it receives more energy and warmth.
How it Creates Seasons:
* Summer: When a hemisphere is tilted towards the Sun, it receives more direct sunlight and experiences longer days. This leads to warmer temperatures and summer.
* Winter: When a hemisphere is tilted away from the Sun, it receives less direct sunlight and has shorter days. This results in colder temperatures and winter.
* Spring and Autumn: These are transitional periods where the amount of daylight and temperatures change gradually as the Earth moves in its orbit.
Key Point: It's important to remember that it's not the distance from the Sun that primarily causes seasons, but the tilt of the Earth's axis.
