Topple Me Not

Topple Me Not


This photo had been processed into black and white with an effort to try to reproduce the green colour of the leaves as white as possible as achieved in infrared photography. The title was credited to the small stack at the foreground which had a rather thin base due to erosion as said in my geography class.


Wind erosion is the result of material movement by the wind. There are two main effects. First, wind causes small particles to be lifted and therefore moved to another region. This is called deflation. Second, these suspended particles may impact on solid objects causing erosion by abrasion.

Wind erosion generally occurs in areas with little or no vegetation, often in areas where there is insufficient rainfall to support vegetation. An example is the formation of sand dunes, on a beach or in a desert. Windbreaks are often planted by farmers to reduce wind erosion. This includes the planting of trees, shrubs, or other vegetation, usually perpendicular or nearly so to the principal wind direction.
