How do tides occur in oceans?

Tides are caused by gravitational pull of large celestial bodies. I will try to cover most of the things related with tides in simple points below - 1. read more

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. read more

In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996). read more

The area where the moon’s gravity interacts directly with the water bodies is the place where the high tides occur (when the moon is either directly above that area). The area whose face makes a 90 degree with the gravitational field is the location of the occurrence of the low tides. read more
