2.  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.  Waves
 Tides
 Ocean Currents

4.  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

 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. 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 on Climate:-
 Modification of Temperature
 Modification of Rainfall
 Formation of Mist and Fog
 Formation of thunderous cyclones

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