SAND. The Nitty-Gritty.

 

SAND. The Nitty-Gritty.

Sand particles. It is outlined by size, being finer than gravel and coarser than silt.is a granular material composed of finely divided rock and mineral. The foremost common element of sand is silicon dioxide in the style of quartz. The Earth's landmasses are created of rocks and minerals, as well as quartz, sparkle and mica.

You can find sand at the edge of lakes, the bottoms of rivers, and the seaside. You can find it in mountain valleys, deserts, and of course a sandpit. Where does all this sand come from?

Sand is made when rocks break into tiny, tiny items. For example, wind, ice, and rain knock against high mountain cliffs. Slowly, over scores of years, these forces break off items of rock. The pieces bounce down the mountainside and break off other pieces of rock - while they're also breaking into smaller and smaller pieces themselves. This isn't sand yet, but it's getting there.

Rivers and glaciers also are sensible at creating sand. A river's water rushes on, carrying rocks with it and breaking them into very little items. The ice of a glacier grinds away at the rocks it slowly moves across.

SAND. The Nitty-Gritty.

Another great sand maker is the ocean. Every day, everywhere the world, tides rise and fall, pushing against rocks over and over. Waves tear at the rocks on the shore, carrying them down.

Thanks to the weather, water, and ice, a number of these broken rocks finally get thus small that they become what we call 'sand'.

Now that you simply have all this sand, what are you able to do with it? Sand is used for paving roads. Bricks formed with sand are tougher and stronger than different bricks. Sand is additionally used to filter (or clean) water. Once it's sprayed with nice force against stone or brick, it will get up thick layers of dirt or paint through a method known as 'sandblasting'. And, of course, sand is great for building sandcastles!
