| File info: Earth's rotation and revolution are two fundamental motions that define its movement in space. Rotation: Earth rotates on its axis, an imaginary line passing through its geographic poles. This rotation causes day and night as the Earth spins once every 24 hours. The axis is tilted at an angle of approximately 23.5 degrees relative to its orbit around the Sun. This tilt is responsible for the changing seasons on Earth. The rotation of Earth also influences other phenomena such as the Coriolis effect, which affects the motion of air masses and leads to the formation of global wind patterns and ocean currents. Revolution: Earth revolves around the Sun in an elliptical orbit, following a path known as its orbit. This revolution takes approximately 365.25 days to complete, which is the basis for our calendar year. The elliptical shape of Earth's orbit means that its distance from the Sun varies throughout the year. The combination of Earth's rotation and revolution determines the length of a day and a year. However, due to the tilt of Earth's axis, a solar day (the time it takes for the Sun to return to the same position in the sky) is not exactly 24 hours throughout the year. This variation in the length of a solar day is the reason we have leap years and the extra day in February every four years. The study of Earth's rotation and revolution is crucial in understanding various natural phenomena, including the seasons, climate patterns, and the measurement of time. | ||
