Tides

Tides are rhythmic rise and fall of the ocean’s water. They take place twice a day. There are two types of tides: high (when the water rises to its highest level and covers much of the seashore) and low (when the water falls to its lowest level and moves away from the shore) tide. Tides occur due to the gravitational pull of the Moon and the Sun. Moon pulls the nearest water-body towards it and a broad swell or a wave is created. During new Moon and full Moon, the Sun and the Moon are in the same line with the Earth and the pull of the wave is the highest, which is known as Spring Tide. And when the Moon is in its first and last quarter, the ocean water is drawn in diagonally opposite directions by the gravitational pull of the Sun and low tides are experienced. These are called Neap Tides.
