Correct option is A
The correct answer is (A) A-IV, B-II, C-I, D-III
Explanation:
• Soil Quality (A-IV): This is often used interchangeably with "Soil Health." It refers to the capacity of a soil to function as a vital living ecosystem that sustains plants, animals, and humans.
• Water Pollution (B-II): Pollution enters water bodies through "Point sources" (identifiable pipes or drains) and "Non-point sources" (diffuse runoff from agricultural fields or urban areas).
• Soil Erosion (C-I): This is the physical process of the "Removal of the fertile top layer" of soil by agents like water and wind.
• Land Capability (D-III): This classification system groups land based on its ability to produce common "Agricultural crops" without deterioration over a long period.
Information Booster:
• Land Capability Classification (LCC) divides land into eight classes (I to VIII). Classes I-IV are suitable for cultivation, while V-VIII are not.
• Soil erosion is often called "creeping death" of the soil because it happens slowly and depletes fertility over time.
Additional Knowledge:
• Point source pollution examples: Factory discharge, sewage treatment plants.
• Non-point source pollution examples: Fertilizer runoff, sediment from construction sites.
• Soil Health emphasizes the biological aspect and the soil as a living entity, whereas Soil Quality often focuses more on chemical and physical productivity parameters.
