Chemical Sedimentary Rocks

Chemical sedimentary rocks form by precipitation of minerals from water Precipitation is when dissolved materials come out of water For example Take a glass of water and pour some salt halite into it The salt will dissolve into the water If you set the water in a hot and dry place like Arizona the water but not the salt will
