![]() ![]() This means that the high tide bulges are never directly lined up with the Moon, but a little ahead of it. Because the Moon is orbiting in the same direction as the Earth rotates, it takes extra time for any point on our planet to rotate and reach exactly below the Moon. Earth’s tidal bulges don’t line up exactly with the Moon’s position.From our view on Earth, these tides coincide with certain lunar phases since they occur when the Moon reaches specific positions in its orbit. When the Sun is at a right angle to the Moon, moderate tides, called neap tides, result. Twice a month, when the Earth, Sun, and Moon line up, their gravitational power combines to make exceptionally high tides, called spring tides, as well as very low tides where the water has been displaced.The timing and heights of the tide near you will be affected by those additional elements. It takes about 29 days, and we see the moon go through its different phases during that. the curved sickle shape of the waxing or waning. Of course, in reality the Earth isn’t a smooth ball, so tides are also affected by the presence of continents, the shape of the Earth, the depth of the ocean in different locations, and more. The lunar cycle is the progression from the new moon through the full moon and back to a new moon again. A sequence of phases of the moon as it revolves around the Earth once every 29.5 days. But research suggests there may be some truth to these ancient theories. Our observer sees the tides rise when passing through the bulges, and fall when passing through the low points. The idea that the lunar cycle can influence people’s behaviour has been largely dismissed by modern medicine. The Moon can also look reddish because Earth’s atmosphere absorbs the other colors while it bends some sunlight toward the Moon. That means that during the night, a full moon fades away as Earth’s shadow covers it up. Rising and ebbing tides happen as Earth’s landmasses rotate through the tidal bulges created by the Moon’s gravitational pull. During a lunar eclipse, Earth gets in the way of the Sun’s light hitting the Moon.The Moon’s gravitational pull on Earth, combined with other, tangential forces, causes Earth’s water to be redistributed, ultimately creating bulges of water on the side closest to the Moon and the side farthest from the Moon. ![]() The low points are where low tides occur. On Earth, the Moon’s gravitational pull causes the oceans to bulge out on both the side closest to the Moon and the side farthest from the Moon. The Moon and Earth exert a gravitational pull on each other.See Tides article where these animations are used. These animations help to explain the science behind how the Moon affects the tides on Earth. ![]()
