Difficulty: EasyLandform Development by Wind Action and Glaciation

Which of the following landforms is created primarily by wind deposition in arid environments?

  1. Barchan duneAnswer
  2. B
    Oxbow lake
  3. C
    Scree slope
  4. D
    Natural levee

Answer

The barchan dune is a landform formed by wind deposition in arid environments.
The barchan dune is a characteristic crescent-shaped dune formed by aeolian deposition where wind direction is dominant and sand supply is moderate.

Step-by-Step Solution

1
Identify the primary geomorphic agent requested in the question stem.
The agent specified is wind (aeolian process) operating in an arid environment via deposition.
Differentiating between erosional and depositional aeolian landforms is necessary to isolate the correct feature.
2
Evaluate the landform choices based on their active process and shaping agent.
Barchans are crescent-shaped sand dunes formed when wind deposits sand grains. Oxbow lakes and levees are fluvial landforms created by running water, while scree slopes are produced by mechanical weathering and mass wasting.
Classifying each landform eliminates fluvial and mass wasting distractors.
