“Soil is formed by water.” If you agree to this statement then give reasons
उत्तर
Water aids in soil development in the following ways:
- Over time, water causes the 'wear off' of rocks.
- It also causes the rocks to rub against one another, resulting in minute particles that are carried downstream and deposited as soil.
- When water freezes in rock cracks, it expands and breaks the rock into smaller pieces.
