Choose the correct statement:
Show Hint
- Porosity of weathered granite is less than a crystalline granite.
- Coarse sands have high porosity and high permeability.
- Clays have high porosity and high permeability.
- Groundwater table does not fluctuate with water recharge.
The Correct Option is B
Solution and Explanation
Step 1: Understanding the statements.
- (A) Weathered granite generally has higher porosity than crystalline granite, making this statement incorrect.
- (B) Coarse sands do indeed have high porosity and high permeability because they allow water to flow through more easily.
- (C) Clays have high porosity, but their permeability is low due to the fine particles, making this statement incorrect.
- (D) Groundwater table fluctuates with water recharge, so this statement is incorrect.
Step 2: Conclusion.
The correct answer is (B) Coarse sands have high porosity and high permeability.
