______ is the process by which water-soluble salts accumulate in the soil.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Salinization.
The process by which water-soluble salts accumulate in the soil is called salinization. This typically occurs in arid and semi-arid regions where evaporation rates are high, drawing water (and dissolved salts) to the soil surface. When the water evaporates, the salts are left behind, leading to their concentration in the soil profile. This accumulation can severely hinder plant growth and agricultural productivity.
