Detailed explanation-1: -Between the winter and summer solstices, daylight increases as Earth continues its orbit around our Sun. During the equinoxes, sunlight strikes perpendicular to the surface at Earth’s equator. All locations on Earth, regardless of latitude, experience 12 hours of daylight and 12 hours of darkness.
Detailed explanation-2: -The Sun is the source of almost all energy on Earth. In fact, the Sun is the main source of heat and light for all the planets in the Solar-system.
Detailed explanation-3: -During winter, the Northern Hemisphere leans away from the sun, there are fewer daylight hours, and the sun hits us at an angle; this makes it appear lower in the sky. There is less heating because the angled sun’s rays are “spread out” rather than direct. (Shadows are longer because of the lower angle of the sun.)
Detailed explanation-4: -The amount of sun a region receives depends on the tilt of the earth’s axis and not its distance from the sun. The northern hemisphere experiences summer during the months of June, July, and August because it is tilted toward the sun and receives the most direct sunlight.
