Solution
Over-grazing encourages soil
A
acidity
B

medium Difficulty
Verified Correct Answer: Option C
Biological Concept & Syllabus Guide
Overgrazing is a phenomenon that occurs when livestock, such as cattle, sheep, or goats, graze a piece of land excessively, leading to detrimental impacts on the soil and vegetation. The loss of vegetation due to overgrazing exposes the soil to erosion by wind and water. Without the stabilizing effect of plants, soil particles become more susceptible to being carried away by wind and rain.
