Question

“Soil is formed by water.” If you agree with this statement, then give reasons.

Answer 1

Soil is the thin layer of material covering the earth's surface and is formed from the weathering of rocks. It is made up mainly of mineral particles, organic materials, air, water and living organisms—all of which interact slowly yet constantly.

⏬ANSWER⏬

Yes, water causes weathering of rocks by following three methods:

1. Wetting and drying: Certain constituents of rocks can pick up moisture and swell up. They contract on drying. Such components (i.e., chemicals) help in breaking of rocks.

2. Frost action: Water seeps into rock crevices and cracks and may freeze if the temperature goes below 0°C. Frozen water expands and exerts a huge pressure sufficient to break all rocks.

3. Abrasion: Beating of rocks by rain and hail, wave action on shores and abrasion caused by trumbling rock fragments in running water batter and grind the rocks into smaller and smaller particles. Water carries these particles depositing them downstream. This produces soil (e.g., sand particles) at a far away place from the parent rock.
