erg, reg, yardangs, zeugens, barchans, seif

Question 2

erg…

formed by deposition- wind carrying particles of sand and then deposits it to create this landform .

Question 3

reg…

Answer 3

ridges run parallel to the prevailing wind.
alternating vertical bands of hard and soft rock.

Question 5

zeugens…

Answer 5

(rock pedestals)
alternating horizontal bands of hard and soft rock.
mushroom shaped rock outcrop.
formed by saltation-severe wind erosion close to the ground surface.

Question 6

barchans…

Answer 6

formed in erg areas.
a form of sand dune.
created due o the prevailing wind and sand deposition-creating the crescent like shape.

Question 7
