📚 Topic Summary
Earth's rotation is the spinning of our planet on its axis, an imaginary line passing through the North and South Poles. This rotation takes approximately 24 hours to complete, which we experience as a day and night cycle. As Earth rotates, different parts of the planet face the Sun, resulting in daylight, while the opposite side is in darkness, experiencing night. Understanding this simple concept is key to understanding many other phenomena on Earth!
