Approximately 71% of the earth’s surface is covered by oceans, which are dynamic in nature. Oceans are considered as a potential resource of food, minerals and power. It is significant for trade and navigation. Ocean water is dynamic. There are two types of movements in water bodies— horizontal and vertical. Its movement is influenced by temperature, salinity, density and the external forces like sun, moon and winds.
The ocean currents and waves are in horizontal motion. The vertical motion refers to the tides. Waves are the undulations formed on the surface of water bodies like river, sea and ocean. Waves are produced by wind pu ushing the water towards the shore. The periodical rise and fall of the oceanic water is called tides. It is due to the attraction of Sun and Moon, once or twice in a day. Please refer Class 11 Geography Chapter 14 Movements of Ocean Water Notes for more information.
