Describe how the tilt of Earth's axis affects the intensity of seasons.

• It causes the Sun to be closer to Earth during summer.

• It changes the angle at which sunlight hits Earth, affecting temperature.

• It alters the speed of Earth's rotation, changing day length.

• It shifts the position of the equator, affecting climate zones.
