The natural phenomenon created by the gravitational pull of the moon is called tides. Tides are the cyclic rise and fall of sea levels caused by the gravitational attraction of the moon and, to a lesser extent, the sun. As the moon orbits the Earth, its gravity pulls water toward it, creating a bulge in the oceans known as high tide. Conversely, areas not in line with the moon experience low tide. Tidal patterns vary in frequency and intensity depending on geographical location and the alignment of the Earth, moon, and sun, influencing coastal ecosystems and human activities.
