2. Movements of ocean water You all know that the ocean water is never still. There are different types of movements of ocean water under the influence of different physical characteristics like temperature , salinity, density, etc. Movements of ocean water are also affected by external forces like the sun, moon and the winds.

3. The major movements of the ocean waters:- Waves Tides Ocean Currents

4. Ocean Currents The ocean currents are the horizontal flow of a mass of water in a fairly defined direction over great distances. They are just like a river flowing in an ocean. Ocean currents can be formed by the winds, density differences in ocean waters due to differences in temperature and salinity. The direction of movement of an ocean current is mainly influenced by the rotation of the earth

5. Causes of Origion Temperature Difference Salinity Differences The Earth’s Rotation The Planetary Winds

6. Types of Ocean Currents Warm Ocean Currents Cold Ocean Currents

7. Types of Ocean Currents Warm Ocean Currents Cold Ocean Currents Those currents which flow from equatorial regions towards poles which have a higher surface temperature and are called warm current. They bring warm waters to the cold regions. Those currents which flow from polar regions towards equator have a lower surface temperature and are called cold currents. They bring cold waters into warm areas .

20. Effects of the Ocean Currents Ocean currents are very important for human beings. Climate and Trade or Economy both are deeply affected by ocean currents. Major influences made by ocean currents are : Effects on Climate Effects on Trade & Economy

21. Effects of the Ocean Currents Effects on Climate:- Modification of Temperature Modification of Rainfall Formation of Mist and Fog Formation of thunderous cyclones

22. Effects of the Ocean Currents Effects on Trade & Economy:- On Port’s Trade Fish Trade Trade of Perishable Goods Fishing Banks
