What is Sand

Sand is a granular material composed of finely divided rock and mineral particles. Sand has various compositions but is defined by its grain size. Sand grains are smaller than gravel and coarser than silt.Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.

Titan's Smoggy Sand Grains

 · On Earth, sand grains form by breaking things down, but on Titan, the opposite may be true - with much of the sand a product of building things up. That's one theory Cassini scientists are considering after studying Titan's massive sand dunes with the visible and infrared mapping spectrometer on the Cassini Saturn orbiter.

Particle size, shape and sorting: what grains can tell us

Remember that for sediment sizes > fine sand, the coarser the material the greater the flow velocity needed to erode, transport & deposit the grains Grain size What does this tell you? If grains are the same size this tells you that the sediment was sorted out.

World Atlas of Sands » Blog Archive » Shape of sand grains

 · Sand grains occurr in different shapes and sizes according to mineral composition, age, transport mechanism and distance traveled. Old sands usually have a round shape due to repeated wheatering and action of external factors. If they are exposed to strong wind or tidal action, the roundness of the grains are more accentuated as for the more.

 · Sand is particulate matter that's larger than silt and smaller than gravel. Different specialists set different limits for sand: Engineers call sand anything between 0.074 and 2 millimeter, or between a U.S. standard #200 sieve and a #10 sieve. Soil scientists classify grains between 0.05 and 2 mm as sand, or between sieves #270 and #10.
