Question

What causes the seasons? Choose one: A. The tilt of the Earth's rotation axis to its orbit around the Sun causes parts of the Earth to experience more direct illumination from the Sun and longer days during the summer than the winter. B. The Sun varies in brightness throughout the year due to cyclical changes in the number of sunspots on its surface. C. The elliptical shape of Earth's orbit around the Sun causes the Earth to be closer to the Sun during the summer than the winter. D. The tilt of the Earth's rotation axis to its orbit around the Sun causes the hemisphere tilted toward the Sun to be warmer than the opposite hemisphere because it is physically closer to the Sun.

Answer 1

A. The tilt of the Earth's rotation axis to its orbit around the Sun causes parts of the Earth to experience more direct illumination from the Sun and longer days during the summer than the winter.

The changing angle at which sunlight strikes the Earth's surface due to the tilt of its axis is what leads to the seasonal variations in temperature and daylight hours. This tilt causes different parts of the Earth to receive varying amounts of solar energy throughout the year, resulting in the four seasons: spring, summer, autumn (fall), and winter.
