Sand dunes
Over time dunes can grow, shrink, or move in the direction of prevailing winds. Dunes can be created and destroyed by either nature or humans. Dunes can roll over trees and buildings, or be washed away by storms.http://coastalcare.org/educate/sand-dunes/

Glacier
Glaciers begin to form when snow remains in the same area year-round, where enough snow accumulates to transform into ice. Each year, new layers of snow bury and compress the previous layers. http://nsidc.org/cryosphere/glaciers/questions/formed.html

Wave Erosion
Coastal erosion is the wearing away of land or the removal of beach or dune sediments by wave action,tidal currents, wave currents, or drainage (see alsobeach evolution). Waves, generated by storms, wind, or fast moving motor craft, cause coastal erosion, which may take the form of long-term losses of sediment and rocks, or merely the temporary redistribution of coastal sediments; erosion in one location may result in accretion nearby.http://www.princeton.edu/~achaney/tmve/wiki100k/docs/Coastal_erosion.html
