Salinity is the process of what in environmental terms?

• A. Salting of the land through watertables
• B. Erosion of soil by water
• C. Increase in soil fertility
• D. Flooding from rainfall

Answer: (A)

Salinity is the buildup of soluble salts in soil and near the surface as groundwater rises toward the root zone (watertables) and salts are drawn upward by capillary action, with evaporation concentrating them at the surface. This process lowers soil quality and makes it harder for plants to take up water, leading to reduced growth or damage. It differs from erosion (which removes soil), from increasing soil fertility (which would improve productivity), or from rainfall flooding (which adds water but doesn’t inherently concentrate salts). The essential idea is that salts move from the groundwater to the surface and accumulate in the soil.
