Question 0

Erosion: Yardangs -

Answer 0

Sculpted landforms, streamlined by desert winds.

Question 1

Erosion: Abrasion -

Answer 1

Wind propels particles at a cohesive rock and wears it down.

Question 2

Erosion: Venifacts -

Answer 2

Aerodynamically shaped rock, cut and polished by the wind.

Question 3

Erosion: Desert pavement -

Answer 3

Remaining particles are too large to be removed by the wind. Finer material is protected below.

Question 4

Erosion: Deflation is the removal of

Answer 4

Unconsolidated material by lifting it into the air or rolling it along the ground.

Question 5

Erosion: Deflation occurs when the ground surface

Answer 5

Consists of dry, loose material.

Question 6

Erosion: Deflation basins are called

Question 7

Transport: The amount of material that can

Answer 7

Be moved depends on the speed of the wind.

Question 8

Transport: Vegetation can bind

Answer 8

Some small particles together the resist deflation.

Question 9

Transport: Suspension -

Answer 9

Fine particles are carried by the wind.

Question 10

Transport: Saltation -

Answer 10

Particles can leap high because of the low density of air; Sand sized particles can be carried by saltation.

Question 11

Transport: Surface creep -

Answer 11

Sand grains striking ground can push another grain forward by up to six times it’s own diameter.

Question 12

Deposition: leads to

Answer 12

Dune formation.

Question 13
