Question

Wavy projections found in desert regions are known as:
(a) Sand dunes
(b) Ripples
(c) Barkhan
(d) Loess

Answer 1

(A) Sand Dunes are appropriate, but the specification that they are wavy leads me to believe the answer is (C).

(B) Ripples are observed in water, as you may know, and are not very wavy.

(C) Barchan means a crescent-shaped (somewhat wave-like) sand formation formed by the wind in deserts.

(D) Loess is not correct. That's something to do with mountains.

Answer 2

Answer:

the answer is the (c) Barkhan
