Question

Difficulty: EasyLandform Development by Wind Action and Glaciation

Match each physical geography feature below with its corresponding process and landform type.

  • YardangAeolian erosional landform produced by wind abrasion on vertical bands of hard and soft rock
  • BarchanAeolian depositional crescent-shaped sand dune with horns extending downwind
  • CirqueGlacial erosional armchair-shaped hollow carved out by ice movement
  • MoraineGlacial depositional ridge composed of unsorted till deposited at glacier margins

Answer

Yardang matches Aeolian erosional landform produced by wind abrasion; Barchan matches Aeolian depositional crescent-shaped sand dune; Cirque matches Glacial erosional armchair-shaped hollow; Moraine matches Glacial depositional ridge composed of unsorted till.
Each feature is correctly matched to its active agent (wind or moving ice) and whether the process involved is erosional or depositional.

Step-by-Step Solution

1
Identify the primary erosional wind landform
Yardang corresponds to wind abrasion acting on alternating rock strata.
Yardangs are distinct wind-eroded ridges found in arid environments.
2
Identify the primary depositional wind landform
Barchan corresponds to crescent-shaped sand deposition.
Barchans develop under wind action where sand supplies are moderate and winds blow from a single direction.
3
Identify the primary erosional glacial landform
Cirque corresponds to the steep-walled, armchair-shaped mountain hollow.
Cirques are created at the source of mountain glaciers by freeze-thaw weathering and ice plucking.
4
Identify the primary depositional glacial landform
Moraine corresponds to ridges composed of unsorted glacial till.
Moraines are formed when glaciers deposit rock debris as they melt or retreat.
