← GeographyWhich consequence results when overgrazing reduces bioturbation rates?
A)Decreased aggregate stability, increased soil erosion✓
B)Accelerated mineral weathering, faster soil creation
C)Enhanced nutrient cycling, greater plant growth
D)Reduced surface albedo, greater heat absorption
💡 Explanation
Decreased bioturbation inhibits soil organisms breaking down organic molecules; decreased aggregate mixing accelerates erosion because soil structure is weakened by reduced earthworm activity and root penetration; therefore decreased stability favors erosion rather than stability's positive contributions.
