Final answer:

The rocks known as ventifacts are faceted by the wind. Depositions refer to the process of material accumulation, haboobs are dust storms, yardangs are larger wind-eroded ridges, and inselbergs are isolated rock hills on a plain.

Step-by-step explanation:

The correct answer to the question is b. Ventifacts. Rocks that have been shaped by wind erosion typically in desert environments are known as ventifacts. Wind-driven sand abrades the surface of rocks, faceting them into distinctive shapes. Unlike ventifacts, the other options provided have the following meanings:

  • Depositions: A geological process where material is added to a landform.
  • Haboobs: Intense dust storms observed in the Sahara, the Arabian Peninsula, and North America.
  • Yardangs: Long, ridged landforms that are sculpted by wind erosion, generally larger features than ventifacts and often found in groups.
  • Inselbergs: Isolated rock hills or mountains rising abruptly from a more gently sloping or virtually level surrounding plain.

Sedimentary rocks, which include materials deposited by wind, often show features such as cross-bedding, where angled layers indicate the direction of wind or water flow that deposited them.
