Consider the following statements: The warmest water in the oceans ...
The correct answer is option D, which states that statement 4 only is correct. Let's examine each statement to understand why.
1. The warmest water in the oceans is found in Equatorial Regions.
- This statement is incorrect. While it is true that the Equatorial Regions receive direct sunlight and experience high temperatures, the warmest waters in the oceans are actually found in the tropics, which are slightly further away from the equator. The warm waters in the tropics are caused by the trade winds and ocean currents, such as the Gulf Stream.
2. The most saline waters in the ocean are found in Equatorial Regions.
- This statement is incorrect. The salinity of ocean water is influenced by several factors, including evaporation, precipitation, and the input of freshwater from rivers. The Equatorial Regions receive high amounts of rainfall, which dilutes the salinity of the water. Therefore, the most saline waters are typically found in regions with high evaporation rates, such as the subtropics.
3. Equatorial waters have the richest nutrients as compared to the oceans.
- This statement is incorrect. Nutrient-rich waters are usually found in areas where there is upwelling, which occurs when cold, nutrient-rich water from the depths of the ocean rises to the surface. While upwelling can occur in some equatorial regions, it is more commonly found in coastal areas and regions influenced by ocean currents, such as the eastern boundary currents.
4. The Polar Regions have relatively lesser salts.
- This statement is correct. The Polar Regions, particularly the Arctic and Antarctic, have lower salinity compared to other parts of the ocean. This is mainly due to the presence of large amounts of freshwater from melting ice and the input of freshwater from rivers. The cold temperatures and limited evaporation also contribute to the lower salinity in these regions.
In summary, only statement 4 is correct, while statements 1, 2, and 3 are incorrect. The warmest waters are found in the tropics, the most saline waters are found in the subtropics, and nutrient-rich waters are typically found in areas with upwelling rather than solely in equatorial regions. The Polar Regions have relatively lower salinity due to the presence of freshwater and limited evaporation.

Consider the following statements: The warmest water in the oceans ...
- The warmest waters in the oceans are found in sub-tropical Regions. Equatorial zones receive lesser insolation due to cloud cover and huge torrential downpours moderate the temperature. So, statement (1) is not correct.
- The most saline waters in the oceans are found in sub-tropical Regions. Equatorial zones receive more insolation due to less cloud cover (as in high-pressure region) and lack of rain in the 'Horse' latitudes result in greater salinity. So, statement (2) is not correct.
- Equatorial zones have feeble upwelling and have relatively richer nutrients, but they are not the areas of the richest nutrients. So, statement (3) is not correct.
- The Polar Regions have a great amount of influx from the melting snow and hence they are relatively very less saline. So, statement (4) is correct.
Therefore, the correct answer is d.
