The movements that occur in oceans are broadly categorised as waves, tides, and currents.
The factors affecting these movements of ocean water are as follows:
(a) Waves are formed as a result of winds, earthquakes, volcanic eruptions, and underwater landslides.
(b) Tides are caused by the strong gravitational pull exerted by the Sun and the Moon on the Earth’s surface.
(c) Another factor affecting the movement of ocean water is temperature. Ocean currents are formed because of the temperature differences between the ocean water present at different latitudes.
