← GeographyWhich mechanism most directly causes detachment of sea stacks?
A)Hydraulic action fracture widening✓
B)Seismic intensity increase erosion
C)Decreased fluvial abrasion impact
D)Haloclasty sediment cohesion increases
💡 Explanation
Hydraulic action fractures surrounding sea stacks, because the force of water compresses air within cracks, thus widening fissures; therefore detachment accelerates rather than sediment cohesion because haloclasty is slower and dependent on salt crystallization.
