ETYM as. sand; akin to Dutch zand, German sand, Old High Germ. sant, Icel. sandr, Dan. and Swed. sand, Greek.
A loose material consisting of grains of rock or coral.
Loose grains of rock, sized 0.0625–2.00 mm/0.0025–0.08 in in diameter, consisting chiefly of quartz, but owing their varying color to mixtures of other minerals. Sand is used in cement-making, as an abrasive, in glass-making, and for other purposes.
Sands are classified into marine, freshwater, glacial, and terrestrial. Some “light” soils contain up to 50% sand. Sands may eventually consolidate into sandstone. + prikaži više
