Question

The Northern and Southern Hemispheres of Earth experience four seasons during the

year. What is the main reason for the change in seasons?
the rotation of the Earth on its axis

Answer 1

Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
