what is deflation
the removal of small particals by wind leaving heaver particals behind
what causes desert pavement
small particals are removed and leave large ones

what are sand spits
similar to sand bars but curved back to the shore
what are some things that can cause mass-wasting
snow heavy rain earthquakes or human activity
