sand dune
Deflation
wind A+
The dune is a obstruction and sand accumulates wherever an obstruction crosses its path and slows its movement.
Its being blown and carried away by wind through the process of deflation.
Wind ErosionTwo processes of aeolian erosion? 1. Deflation - wind entrains particles with a diameter of less than 60 micrometres.2. Abrasion - entrained sediment is thrown against rock surfaces. ("wind-scouring").Hope this helps.
probably somethin due to gravity or something like that
Sand dunes are cause by the movement of sand by the wind or water.
I am interested in the answer to the same question: is there a place close to Michigan City , Indiana where you can rent a dune buggy, or is there a Dune Buggy business close by?
Desert pavement is the result of deflation - fine materials being removed by agents of erosion. Sand dunes are the result of deposition of fine materials by the wind.
Inflation is when the value of money declines so it takes more dollars to purchase the same goods or services. Deflation is the opposite.
merits and demerits of deflation
