rock+cycle

suddenly a valcano erupting and scorching hot balls of liqhid rock. Shut out and laying wast to the vally guickly cool into solid rock.this is the begging of the rock cycle. in about a thausand years you would no idea it ever happend.but how could solid rockjust disaper becase of weathering three simpale forces like wind,water,and gravity. Well wind picks up sand,small rocks,twigs and other matereals wich fly and smack into a rock and chips it ever so slitly over along period of time it terns to sand. water on the other hand smashes into rocks with termendis force whereing it smoth that's why the pebbles on the beach are smoth and shiny also how under water caves and crevises ware the rock is softer and more britale. then gravity pulls it to the center of the earth .were it melts and evenculy comes back up and terns to all cinds of rock it mostly dipends on how fast it drys and how hot or cold it is.you cant really afeck this cycle other than making it erode faster by kicking it or making a tunle .the most inportant thing is with out rocks we would have no food becouse sand terns into soil and we need soil to grow food.with out rocks there wold be no trees so thar would be no houses .with out soil there would be no air so no life .and farming gives a lot of peaple new jobs
