I is incorrect: Mushroom rock in a desert → Wind abrasion. Sand-laden winds erode lower rock surfaces strongly. II is correct: Sand spit along a coast → Longshore sediment deposition. Obliquely approaching waves drive sediment along the shore.

Correct answer: B

I is correct: Delta at a river mouth → Deposition exceeding removal. Sediment builds where a river enters relatively still water. II is correct: Alluvial fan at a mountain front → Deposition as stream gradient falls. A stream loses carrying capacity on entering a flatter area.

Correct answer: A

Water can reduce slope stability and trigger downslope movement.

Correct answer: B

I is correct: Exfoliation of exposed rock → Physical weathering. Outer rock layers peel away without requiring chemical alteration. II is correct: Sinkhole in limestone terrain → Solution and collapse. Dissolution enlarges underground openings that may collapse.

Correct answer: C

I is incorrect: Sand spit along a coast → Longshore sediment deposition. Obliquely approaching waves drive sediment along the shore. II is correct: U-shaped mountain valley → Glacial erosion. A moving glacier widens and deepens a valley.

Correct answer: A

A glacier transports and deposits unsorted material.

Correct answer: C

I is incorrect: Exfoliation of exposed rock → Physical weathering. Outer rock layers peel away without requiring chemical alteration. II is correct: Landslide on a saturated slope → Mass movement under gravity. Water can reduce slope stability and trigger downslope movement.
