← GeographyWhich topographical consequence results when permafrost soil exhibits heightened instances of bioturbation?
A)Increased rates of thermokarst formation✓
B)Decreased aggregate soil stability
C)Enhanced surface water infiltration
D)Lowered susceptibility to wind erosion
💡 Explanation
Increased bioturbation in permafrost accelerates thawing and landscape collapse because cryoturbation decreases, promoting soil mixing that introduces organic matter which enhances microbial activity. Therefore, thermokarst formation increases rather than soil stabilization processes that require frozen soil for stability.
