Understanding Seasons and Their Changes

The video explains why Earth has seasons, focusing on the tilt of Earth's axis and its orbit around the sun. This tilt causes different parts of Earth to receive varying amounts of sunlight throughout the year, leading to seasonal changes. The video also discusses how the equator experiences consistent temperatures, while the poles have extreme seasonal shifts. It outlines the start dates of seasons in the northern hemisphere and highlights the opposite nature of seasons in the southern hemisphere.

What is the primary reason for the change in seasons on Earth?

• The tilt of Earth's axis

• The speed of Earth's rotation

• The distance of Earth from the Sun
