Question

6. What makes the fresh rainwater become saline after reaching the earth's surface?

Answer 1

• Water is a universal solvent because it dissolves a large number of substances.
• When rain falls, it dissolves salts and many other minerals which are present on the earth.
• The rainwater passes through many different layers of the earth, rocks, and mountains. So, it dissolves a large number of salts and different minerals.
• Hence, the fresh rainwater becomes saline after reaching the earth's surface.
