← GeographyWhich risk increases when desert shrub roots decay?
A)Increased sand dune migration rate✓
B)Elevated rate of chemical weathering
C)Decreased albedo of sandstone bedrock
D)Acceleration of playa lake sedimentation
💡 Explanation
The risk of increased sand dune migration increases because decreased root cohesion from decaying desert shrub roots reduces stabilization; therefore, dunes advance rather than remaining stationary, even with wind breaks, rather than accelerating bedrock or lake changes.
