Question
What causes the seasons on Earth?
✓
Answer
The seasons on Earth are caused by the Earth's axial tilt of 23.5 degrees and its revolution around the Sun. This tilt causes different hemispheres to receive more direct sunlight at different times of the year, leading to variations in temperature and day length that define the seasons.
