Rocks formed this way are called sedimentary rocks. Examples include sandstone, which forms from sand grains limestone, which consists of the shells of small organisms and deposits of salt and gypsum, which form from the evaporation of water containing these minerals. Sometimes, sedimentary rocks can build up into layers several miles thick.

The Slow Carbon Cycle. Through a series of chemical reactions and tectonic activity, carbon takes between 100-200 million years to move between rocks, soil, ocean, and atmosphere in the slow carbon cycle. On average, 10 13 to 10 14 grams (10100 million metric tons) of carbon move through the slow carbon cycle every year.

What Happens When Acid Reacts With The Naked Scientists

Jun 15, 2008 Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks dont dissolve very quickly. But if you add an acid, you add hydrogen ions (H), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen
