DIRECTIONS : The followingitems consist of two statements, Statement I...
Both the statements are individually true and statement II is the correct explanation of statement I. Higher the rate of evaporation, higher is salinity. The Highest evaporation has been recorded along the tropic of Cancer and that is one of the reasons that region of Red Sea and Persian Gulf has one of the highest salinity.

DIRECTIONS : The followingitems consist of two statements, Statement I...
Statement I: There is high salinity in Red Sea.
Statement II: Rate of evaporation is high in Red Sea.
Explanation:
The correct answer is option 'A' which states that both the statements are individually true and Statement II is the correct explanation of Statement I.
Salinity in Red Sea:
The Red Sea is known for its high salinity. Salinity refers to the concentration of salt in water. The Red Sea has a higher salinity compared to other seas and oceans. The average salinity of the Red Sea is around 40 parts per thousand, which is significantly higher than the global average of 35 parts per thousand. This high salinity is due to various factors including evaporation, lack of freshwater inflow, and limited connection to other water bodies.
Evaporation in Red Sea:
The Red Sea experiences high rates of evaporation. Evaporation is the process by which water changes from a liquid state to a gaseous state. The rate of evaporation depends on various factors including temperature, humidity, and wind speed. In the case of the Red Sea, the high temperatures and low humidity levels contribute to a high rate of evaporation. The region surrounding the Red Sea is arid with limited rainfall, which further enhances the evaporation process.
Relationship between Salinity and Evaporation:
The high salinity in the Red Sea is primarily a result of the high rate of evaporation. As water evaporates from the sea surface, the dissolved salts are left behind, increasing the salinity of the remaining water. This process is known as "evaporative concentration." Since the Red Sea experiences high rates of evaporation, the concentration of salt in the water increases, leading to high salinity.
Conclusion:
Both Statement I and Statement II are individually true and Statement II is the correct explanation of Statement I. The high salinity in the Red Sea is a result of the high rate of evaporation in the region.
