Tidal range Tidal range Tidal range is the height difference between high tide and low tide. Tides are the rise and fall of sea levels caused by gravitational forces exerted by the Moon and Sun and the rotation of Earth. Tidal range is not constant but changes depending on the locations of the Moon and Sun. The most extreme tidal range occurs during spring tides, when the gravitational forces of both the Moon and Sun are aligned (syzygy), reinforcing each other in the same direction (new moon) or in opposite directions (full moon). During neap tides, when the Moon and Sun's gravitational
Total eclipses on the Moon than on Earth with up to around 2.8 hours. Some total-partial eclipses have a most, half or a part of the Moon being in the center of the Earth's shadow. Unlike the Earth which it umbral shadow shows black, as the Moon has no atmosphere, the surface appears red because the only sunlight available is refracted through the Earth's atmosphere on the edges of the earth as it is shown in the sky in a painting by Lucien Rudaux. Total eclipses on the Moon Total solar eclipses on the Moon are caused when the Earth passes in front of the
