Evaluate the two proposed answers. Which are supported? I. Sand spit along a coast — the process primarily responsible: Longshore sediment deposition. II. Stalactite in a limestone cave — the process primarily responsible: Mineral deposition from dripping water.
Correct answer: C
I is correct: Sand spit along a coast → Longshore sediment deposition. Obliquely approaching waves drive sediment along the shore. II is correct: Stalactite in a limestone cave → Mineral deposition from dripping water. Calcium carbonate accumulates from the cave roof.
For Delta at a river mouth, identify the process primarily responsible.
Correct answer: B
Sediment builds where a river enters relatively still water.
Evaluate the two proposed answers. Which are supported? I. Moraine beside a glacier — the process primarily responsible: Physical weathering. II. Ox-bow lake — the process primarily responsible: Meander cutoff.
Correct answer: A
I is incorrect: Moraine beside a glacier → Deposition of glacial debris. A glacier transports and deposits unsorted material. II is correct: Ox-bow lake → Meander cutoff. A river abandons a bend after a shorter channel forms.
Evaluate the two proposed answers. Which are supported? I. U-shaped mountain valley — the process primarily responsible: Glacial erosion. II. Loess blanket — the process primarily responsible: Wind deposition.
Correct answer: C
I is correct: U-shaped mountain valley → Glacial erosion. A moving glacier widens and deepens a valley. II is correct: Loess blanket → Wind deposition. Fine windblown silt accumulates over land.
For Exfoliation of exposed rock, identify the process primarily responsible.
Correct answer: D
Outer rock layers peel away without requiring chemical alteration.
Evaluate the two proposed answers. Which are supported? I. Ox-bow lake — the process primarily responsible: Solution and collapse. II. Landslide on a saturated slope — the process primarily responsible: Mass movement under gravity.
Correct answer: A
I is incorrect: Ox-bow lake → Meander cutoff. A river abandons a bend after a shorter channel forms. II is correct: Landslide on a saturated slope → Mass movement under gravity. Water can reduce slope stability and trigger downslope movement.
Evaluate the two proposed answers. Which are supported? I. Delta at a river mouth — the process primarily responsible: Deposition exceeding removal. II. Sand spit along a coast — the process primarily responsible: Longshore sediment deposition.
Correct answer: C
I is correct: Delta at a river mouth → Deposition exceeding removal. Sediment builds where a river enters relatively still water. II is correct: Sand spit along a coast → Longshore sediment deposition. Obliquely approaching waves drive sediment along the shore.
For Coastal sea arch, identify the process primarily responsible.
Correct answer: A
Waves enlarge weaknesses through a headland.
Evaluate the two proposed answers. Which are supported? I. Alluvial fan at a mountain front — the process primarily responsible: Abrasion by swirling pebbles. II. Moraine beside a glacier — the process primarily responsible: Deposition of glacial debris.
Correct answer: B
I is incorrect: Alluvial fan at a mountain front → Deposition as stream gradient falls. A stream loses carrying capacity on entering a flatter area. II is correct: Moraine beside a glacier → Deposition of glacial debris. A glacier transports and deposits unsorted material.
For V-shaped youthful river valley, identify the process primarily responsible.
Correct answer: C
Vertical erosion dominates in a steep river's upper course.
Evaluate the two proposed answers. Which are supported? I. Moraine beside a glacier — the process primarily responsible: Physical weathering. II. Landslide on a saturated slope — the process primarily responsible: Mass movement under gravity.
Correct answer: B
I is incorrect: Moraine beside a glacier → Deposition of glacial debris. A glacier transports and deposits unsorted material. II is correct: Landslide on a saturated slope → Mass movement under gravity. Water can reduce slope stability and trigger downslope movement.
For Sand spit along a coast, identify the process primarily responsible.
Correct answer: D
Obliquely approaching waves drive sediment along the shore.
Evaluate the two proposed answers. Which are supported? I. Exfoliation of exposed rock — the process primarily responsible: Wind abrasion. II. Ox-bow lake — the process primarily responsible: Meander cutoff.
Correct answer: C
I is incorrect: Exfoliation of exposed rock → Physical weathering. Outer rock layers peel away without requiring chemical alteration. II is correct: Ox-bow lake → Meander cutoff. A river abandons a bend after a shorter channel forms.
For Stalactite in a limestone cave, identify the process primarily responsible.
Correct answer: D
Calcium carbonate accumulates from the cave roof.
Evaluate the two proposed answers. Which are supported? I. Sinkhole in limestone terrain — the process primarily responsible: Deposition of glacial debris. II. Alluvial fan at a mountain front — the process primarily responsible: Deposition as stream gradient falls.
Correct answer: A
I is incorrect: Sinkhole in limestone terrain → Solution and collapse. Dissolution enlarges underground openings that may collapse. II is correct: Alluvial fan at a mountain front → Deposition as stream gradient falls. A stream loses carrying capacity on entering a flatter area.
For Loess blanket, identify the process primarily responsible.
Correct answer: B
Fine windblown silt accumulates over land.
Evaluate the two proposed answers. Which are supported? I. V-shaped youthful river valley — the process primarily responsible: River downcutting. II. Sand spit along a coast — the process primarily responsible: Longshore sediment deposition.
Correct answer: A
I is correct: V-shaped youthful river valley → River downcutting. Vertical erosion dominates in a steep river's upper course. II is correct: Sand spit along a coast → Longshore sediment deposition. Obliquely approaching waves drive sediment along the shore.
Evaluate the two proposed answers. Which are supported? I. Stalactite in a limestone cave — the process primarily responsible: Wind deposition. II. Delta at a river mouth — the process primarily responsible: Deposition exceeding removal.
Correct answer: D
I is incorrect: Stalactite in a limestone cave → Mineral deposition from dripping water. Calcium carbonate accumulates from the cave roof. II is correct: Delta at a river mouth → Deposition exceeding removal. Sediment builds where a river enters relatively still water.
For Mushroom rock in a desert, identify the process primarily responsible.
Correct answer: A
Sand-laden winds erode lower rock surfaces strongly.
Evaluate the two proposed answers. Which are supported? I. River pothole — the process primarily responsible: Abrasion by swirling pebbles. II. Moraine beside a glacier — the process primarily responsible: Deposition of glacial debris.
Correct answer: C
I is correct: River pothole → Abrasion by swirling pebbles. Eddies rotate stones and grind depressions in bedrock. II is correct: Moraine beside a glacier → Deposition of glacial debris. A glacier transports and deposits unsorted material.
For Sinkhole in limestone terrain, identify the process primarily responsible.
Correct answer: D
Dissolution enlarges underground openings that may collapse.
