Question

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

star dunes
parabolic dunes
barchanoid dunes
transverse dunes

Answer 1

As far as I remember, sand dunes that form scalloped rows of sand at right angles to the wind are called barchanoid dunes. I'm pretty sure it's correct.

Answer 2

The correct answer is - barchanoid dunes.

The barchanoid dunes are a variety of dune intermediate between barchan dunes and transverse dunes. The barchanoid dunes are recognizable for the formation of scalloped rows of sand that are perpendicular to the wind that brings in the sand material with it.
