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
Partial/total eclipses on the Moon center of the Earth's shadow while the remainder visilbly as partial, some has 50/50 covered by the center of the Earth's shadow and visibly as partial. The shortest can be for around 2 hours and the longest can be up to 5–6 hours. Partial/total eclipses on the Moon Partial/total Solar eclipses on the Moon are caused when the Earth passes in front of the Sun, blocking a part its light in one part and the whole light in the other. Viewers on Earth will see a partial lunar eclipse. During its eclipses, the Earth will be in new phase, completely
