How does soil act as a natural filter for groundwater?
- A.
Allowing contaminants to pass through to groundwater
- B.
Absorbing and retaining contaminants
- C.
Preventing the infiltration of water into the ground
- D.
Promoting the leaching of pollutants
Correct Answer
B. Absorbing and retaining contaminantsExplanation
Soil acts as a natural filter for groundwater by absorbing and retaining contaminants present in water as it infiltrates into the ground. This filtration process is crucial for maintaining groundwater quality, as soil particles and organic matter trap and immobilize pollutants, preventing them from reaching and contaminating groundwater sources. Understanding soil's role as a natural filter underscores its significance in purifying and safeguarding vital water resources.Rate this question:
