6 days ago · The Short Answer: 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.
Dec 28, 2023 · Earth rotates on its axis every 24 hours, which we consider to be one day (Figure 3.1). Each rotation can be seen in the daily change from day to night. The circle of illumination is the line separating the part of the planet receiving sunlight and the part of the planet in darkness. Why does Earth rotate?

On June 21, the Sun rises north of east and sets north of west. For observers in the Northern Hemisphere of Earth, the Sun spends about 15 hours above the horizon in the United States, meaning more hours of daylight. On December 21, the Sun rises south of east and sets south of west.

At the equator, the sun is directly overhead at noon on these two equinoxes. The "nearly" equal hours of day and night are due to refraction of sunlight or a bending of the light's rays that causes the sun to appear above the horizon when the actual position of the sun is below the horizon.
