← GeographyWhich process increases around a lava done's edge?
A)Shear stress and fragmentation✓
B)Chemical weathering and erosion
C)Isostatic rebound and uplift
D)Hydraulic conductivity and saturation
💡 Explanation
Shear stress raises the risk of rock disintegration as friction raises along a lava dome's margin at boundaries; fracturing follows by frictional fragmentation because material becomes highly unstable and is subjected to continuous deformation, therefore mechanical disintegration will become dominant rather than weathering action, under steady confining conditions.
