Question

Saline soil is predominantly found in _________ of Tamil Nadu.

• A. Hilly districts
• B. Coastal districts
• C. Western ghats
• D. None of these

Answer 1

The correct option is B Coastal districts

Saline soil is predominantly found in coastal districts of Tamil Nadu.

Soil salinisation in coastal areas is due to accumulation of salts from inundated sea water.

Soil salinity is the salt content in the soil; the process of increasing the salt content is known as salinization. Salts occur naturally within soils and water. Salination can be caused by natural processes such as mineral weathering or by the gradual withdrawal of an ocean.
