Question

What are the causes for the occurrence of tides and currents?

Accepted Answer

Tide is defined as the phenomenon of the alternate rise and fall in the level of seawater. Tides are mostly experienced in oceans and seas. Tides mainly occur due to the gravitational pull of the moon and the sun on the surface of the earth. Tides are of two types, namely high tide and low tide. The rise and fall in the seawater level are called high tide and low tide respectively. The relative position of the moon and the sun concerning the earth is responsible for the variation in the height of tides.

The movement of ocean water in the form of a stream in a definite direction on its surface is called an ocean current. Ocean currents develop due to the:

Change in the temperature of ocean water.

Change in the density of water.

The direction of the prevailing winds.

Rotation of the earth.

Shape and position of the coast.
