Earth's rotation refers to the spinning of our planet on its axis, which takes approximately 24 hours to complete one full turn. This rotation is responsible for the cycle of day and night. As Earth spins, different parts of the planet are exposed to the Sun, creating daylight, while the areas turned away from the Sun experience darkness. The axis of rotation is an imaginary line that runs from the North Pole to the South Pole. Earth's rotation is counterclockwise when viewed from above the North Pole. This movement also affects ocean currents and weather patterns, contributing to the planet's diverse climates.
