Question

Explain depositional landforms created by wind?

Answer 1

Instructions:

• Sand dunes
• Crescent dunes
• Longitudnal dunes
• Deflation Hallows

Solution:

• Sand Dunes are created when the speed of wind decreases, huge amount of sand gets deposited and create mounds or hills of sand.
• Based on the shape, Sand dunes are classified into Crescent dunes and longitudinal dunes.
• Crescent dunes, also known as barchans are moon shaped sand dune having two horns.
• Longitudinal dunes are formed parallel to the wind direction. These sand dunes are in the form of extended elongated hill.
• As there are no or very less plants in the desert, the sand is unprotected. As a result strong wind carries sand particles forming huge depressions in the desert forming deflation hallows.
