Consider the following statements about distribution of salinity in wa...
The correct answer is option 'A': 1, 2.
Explanation:
1. Generally, salinity is high in land-locked regions compared to estuaries:
Salinity refers to the amount of dissolved salts in water. In land-locked regions, such as inland seas or closed basins with no outlets to the ocean, water evaporates over time, leaving behind the dissolved salts. As a result, the salinity in these regions tends to be higher compared to estuaries, which are areas where freshwater from rivers or streams mixes with seawater.
2. The salinity variation in the Pacific Ocean is mainly due to its shape and larger areal extent:
The Pacific Ocean is the largest and deepest ocean on Earth, covering a vast area between Asia and the Americas. Its shape and size play a significant role in determining salinity variations. The Pacific Ocean receives freshwater input from various sources, including rivers and precipitation. However, due to its larger surface area and shape, the Pacific Ocean has a relatively low average salinity compared to other oceans. Additionally, the circulation patterns within the Pacific Ocean, such as the Pacific Decadal Oscillation and El Niño-Southern Oscillation, can also influence salinity variations in different regions.
3. The highest salinity is recorded between 0 to 10-degree latitude because of high temperature and high evaporation:
This statement is incorrect. The highest salinity in the ocean is generally found in subtropical regions, around 20 to 30 degrees latitude, rather than between 0 to 10 degrees latitude. In these regions, high temperatures and high evaporation rates contribute to increased salinity. The combination of high temperatures and low precipitation leads to more water evaporating from the ocean's surface, leaving behind a higher concentration of dissolved salts.
In summary, the correct statements are 1 and 2. Salinity tends to be higher in land-locked regions compared to estuaries, and the salinity variation in the Pacific Ocean is mainly influenced by its shape and larger areal extent. The statement about the highest salinity being recorded between 0 to 10-degree latitude is incorrect.
