Heap of Sand

Tall I stand like a mountain or stalagmite growing out of the earth,I can be soft or coarse,tasteless or salty;rough but smooth surfaces;school children play on me and with me;I`m amiable.Trend upon by beach lovers and rest upon by picnickers, Sandwiched between cement and gravel,I contribute to raising of skyscrapers ; married to steel I form pillars, Also known as Silica or quartz glass loved by scientists,as I act as shock and heat absorbers and in controlling frequency of trans- mitters;Linguists can`t do without me..and..&..&..soldiers of war.&.. I share name with birds,humans..&..hurricane; Being blown by strong winds in arid lands,I cause cornea,iris &respiratory problems,which make dwellers wear shoes with rubber soles and goggles made from Me-optical lenses.I`m dynamic,lovely and gracious;I am SAND!You need me in your life.
