What causes high tide and low tide? Why are there two tides each day? In this diagram, you can see that the moon's gravitational force pulls on water in the oceans so that there are bulges in the ocean on both sides of the planet. The moon pulls water toward it, and this causes the bulge toward the moon. The bulge on the side of the Earth opposite the moon is caused by the moon pulling the Earth away from the water on that side. Up Next. If you are on the coast and the moon is directly overhead, you should experience a high tide.
Tides are caused by the gravitational pull of the moon and sun. The tide itself is actually a huge wave with an extremely long wavelength. The wavelength is so long that it is only easily observed in the ocean because of it's size. Tides do occur in lakes and ponds they just aren't noticible. Seas and Oceans have space which air can flow freely without stopped by any objects where as in lake or pond ,the water is less and not that much air flow freely. So the air makes large waves in seas and oceans than the lakes and ponds.
