← GeographyWhich process influences the final slope stability of basaltic lava flows post-eruption?
A)Differential cooling induced thermal contraction.✓
B)Progressive sedimentation over flow surfaces.
C)Localized aeolian deposit accumulation rates.
D)Vegetative root wedging weakening integrity.
💡 Explanation
Differential cooling causes thermal contraction, initiating fracturing and potential slope failure because diverse cooling rates affect internal stresses. Therefore, answer A is correct rather than options B, C, and D, which involve external processes.
