A ) Loess

B ) Sund dunes

C ) Piedmont ✅

D ) Desert Payment


Explanation:

✅ Answer: Piedmont is NOT caused by wind erosion.

Because:

  • Sand dunes → wind erosion ✅
  • Deflation hollows → wind erosion ✅
  • Yardangs → wind erosion ✅
  • Piedmont → ❌ Not wind (formed by water or glacier deposition)

 Explanation:

Piedmont refers to:

A gentle sloping area formed at the base of mountains, usually created by deposition from rivers or glaciers, not by wind.

  • It's typically formed due to alluvial deposits brought by water (streams and rivers) coming down from mountains.
  • Sometimes, glacial or tectonic activity also contributes.
