The video explains why Earth has four seasons due to its axial tilt. This tilt, caused by a massive impact billions of years ago, results in varying sunlight exposure as Earth orbits the sun, creating different seasons. The video also highlights how seasons differ globally, with opposite seasons in the Northern and Southern hemispheres. It concludes by emphasizing the importance of Earth's tilt in understanding seasonal changes.

What causes the Earth to have different seasons?

• The Earth moving closer and farther from the sun

• The moon's gravitational pull

• The Earth's tilt

• Changes in the sun's temperature
