Which of the following specialized erosional landforms is produced in arid regions when wind abrasion selectively removes loose fine-grained particles, leaving behind a desert pavement composed of closely packed pebbles and gravel?

💡 Solution & Explanation

Reg, also known as desert pavement or serir, is a stony desert surface formed when wind deflation strips away sand and silt, leaving a residual veneer of coarser gravel and pebbles. Yardangs are elongated wind-sculpted ridges carved from soft bedrock, whereas ventifacts are individual wind-faceted stones polished by sandblasting. Inselbergs represent isolated residual hills rising abruptly from flat arid plains. Geomorphologists utilize these landscape indicators to reconstruct paleoclimatic wind regimes.
