The revolution of the Earth refers to its orbit around the Sun, which takes approximately 365.25 days to complete. This motion is responsible for the changing seasons, as the Earth’s tilted axis causes varying angles of sunlight at different times of the year, influencing temperature and daylight duration.

The Earth’s revolution is its elliptical orbit around the Sun, taking about 365.25 days to complete, leading to the yearly calendar. This movement, combined with the Earth’s axial tilt of about 23.5 degrees, is the primary reason for seasonal changes. As the Earth travels along its orbit, different regions receive varying amounts of sunlight, causing temperature shifts and changes in daylight hours. This process results in the distinct seasons—spring, summer, autumn, and winter—experienced in most parts of the world. The extra 0.25 days are accounted for by adding a leap day every four years, making up for the fractional time.
