Which among the following places record the least salinity? Why?

• Land- locked sea.

• Areas of heavy rainfall.

• Areas of high evaporation.

Areas of heavy rainfall will record the least salinity.

Reason: Salinity refers to the concentration of salt content in water. Since salt is a water-soluble mineral, areas of heavy rainfall with excess water will dissolve the salt and reduce salinity. Land Locked seas and areas of high evaporation will see an increase in salinity as the ratio of salt to water will be high.
