Nothing much to say other than to show here a beautiful sand formation that was created by the rescinding tide, I have another few shots so I will be posting a few more for your satisfaction and of course why not learn a bit about sand?, well, I have and here I share it with you;
Sand is a granular material made up of fine mineral particles, it is a naturally occurring, finely divided rock they are also called particles with a microscopic diameter, individual particle in this range size is termed a sand grain, down The next larger size class above sand is gravel, with particles ranging from 2 mm up to 64 mm, Sand feels gritty when rubbed between the fingers silt by comparison feels like flour.
Study of individual grains can reveal much historical information as to the origin and kind of transport of the grain. Quartz sand that is recently weathered from granite or gneiss quartz crystals will be angular. It is called sharp sand in the building trade where it is preferred for concrete, and in gardening where it is used as a soil amendment to loosen clay soils. Sand that is transported long distances by water or wind will be rounded, with characteristic abrasion patterns on the grain surface. Desert sand is typically rounded.
People who collect sand as a hobby are known as arenophiles or psammofiles, many thanks for you visit and critics. |
