Title: What is Tide
Post by: Anuz on April 25, 2012, 09:45:34 PM

Tides are periodic rises and falls of large bodies of water. Tides are caused by the gravitational interaction between the Earth and the Moon. The gravitational attraction of the Moon causes the oceans to bulge out in the direction of the Moon. Another bulge occurs on the opposite side. Sir Isaac Newton (1642 -1727) was the first person to explain tides scientifically. In 1687, Newton explained that ocean tides result from the gravitational attraction of the Sun and Moon on the oceans of the Earth (Sumich, 1996). There are two types of tide, namely, lunar tide and solar tide. Generally the Tide which is created by the Moon is called lunar tide and the Tide which is created by the Sun is called solar tide.
