Q. Consider the following landforms:

1. Barkhans
2. Yardangs
3. Oasis

Which of the above are typically found in deserts?
Answer: 1, 2 and 3
Notes: Barkhans (crescent-shaped dunes), yardangs (streamlined rock ridges sculpted by wind erosion), and oases (fertile areas with water) are all characteristic landforms of desert regions. Barkhans and yardangs result from aeolian processes, while oases are found where underground water surfaces, supporting vegetation amid otherwise arid conditions typical of deserts.
