Which of the following is/are characteristic features of wind-eroded landforms in desert regions? 1. Formation of mushroom-shaped rocks with a slender base and broad upper cap 2. Development of flat-topped residual hills resembling table surfaces 3. Emergence of rock remnants standing as isolated pedestals
1, 2 and 3 all are correct
All three features are produced by wind erosion (abrasion and deflation) in arid regions.
Statement 1: Mushroom rocks (also called gaur or pedestal rocks) form when wind-driven sand erodes the lower part of a rock more strongly than the top, leaving a slender base and a broad cap. ✓
Statement 2: Flat-topped residual hills like mesas and buttes, with table-like surfaces and steep sides, are typical residual landforms of arid plateaus shaped by wind and water erosion. ✓
Statement 3: Isolated pedestal-like rock remnants (also a form of mushroom rock or pedestal rock) emerge when surrounding softer material is eroded away, leaving harder rock standing alone. ✓
Hence all three statements are correct.
