D. the wind creating desert pavement

3. sand dunes that form scalloped rows of sand at right angles to the wind are called

A. star dunes
B. parabolic dunes
C. transverse dunes
D. barchanoid dunes

Answer 1

A. windblown sand cutting and polishing exposed rock surfaces is the answer

Answer 2

The action of abrasion can best be described as windblown sand cutting and polishing exposed rock surfaces . Correct answer:A A rock undergoes abrasion when particles of sand or small pieces of rock are carried across its surface by a glacier, stream, or the wind.Gravity causes abrasion as a rock tumbles down a slope. Sand dunes that form scalloped rows of sand at right angles to the wind are called Barchanoid dunes. Correct answer: D Barchanoid dunes are formed from long sand ridges oriented at right angles to the wind.
