Verified Answer
With reference to ocean currents, consider the following statements:1....
• Ocean currents are large masses of surface water that circulate in regular patterns around the oceans. Those that flow from equatorial regions poleward have a higher surface temperature and are warm currents. Those that flow from polars regions equator ward have a lower temperature and are cold currents.
• The earth rotation deflects freely moving objects, including oceans currents to the right. In the northern hemisphere, this is a clockwise direction (e.g. The circulation of Gulf Stream Drift and canaries current).In the southern hemisphere, it is an anti-clock direction (e.g. The Brazilian current and the West Wind Drift). Hence statement 1 is not correct.
• Counter equatorial current:
(i) It is an eastward flowing current found in the Atlantic, Indian and Pacific Oceans. Hence statement2 is not correct.
(ii) It is found in between the North Equatorial and South Equatorial Currents at about 3-10 degrees northern latitudes.
(iii) This counter-current replaces the water removed from the eastern side of the ocean by the North Equatorial and South Equatorial Currents.
(iv) In the Indian Ocean, the current tends to reverse hemispheres seasonally due to the impact of reversing Asian monsoons.
(v) In the lower latitudes, the warm currents flow on the eastern shores and cold on the western shores. Hence statement 3 is correct.
(vi) The situation is reversed in the higher latitudes. The warm currents move along the western shores and the cold currents along the eastern shores.

With reference to ocean currents, consider the following statements:1....
Explanation:
Ocean currents are large-scale movements of water within the ocean that are driven by various factors like wind, temperature, salinity, and the Earth's rotation. They play a crucial role in regulating the Earth's climate and redistributing heat around the globe. Let's analyze each statement given in the question:
1. Oceans currents flow in an anticlockwise direction in the northern hemisphere and clockwise in the southern hemisphere.
This statement is correct. Ocean currents in the northern hemisphere are deflected to the right due to the Coriolis effect, which is caused by the rotation of the Earth. As a result, they flow in an anticlockwise direction. In the southern hemisphere, ocean currents are deflected to the left, causing them to flow in a clockwise direction.
2. Counter equatorial current moves from east to west.
This statement is incorrect. The equatorial currents, such as the North Equatorial Current and the South Equatorial Current, flow from east to west along the equator. These currents are driven by the trade winds and form part of the global circulation pattern known as the "gyres." There is no counter equatorial current that moves from east to west.
3. In the lower latitudes, warm ocean currents move along the eastern margins of the continents.
This statement is incorrect. In the lower latitudes, warm ocean currents generally move along the western margins of the continents. This is due to the presence of prevailing winds, such as the trade winds, which push the surface water towards the western side of the ocean basins. As a result, warm currents like the Gulf Stream in the North Atlantic and the Brazil Current in the South Atlantic flow along the eastern coasts of the Americas.
In conclusion, only statement 1 is correct, while statements 2 and 3 are incorrect. It is important to have a clear understanding of ocean currents as they have significant implications on weather patterns, marine ecosystems, and global climate.
