Sedimentary Rocks And The Rock Cycle
Sedimentary rocks are formed by the lithification of inorganic andor organic sediments, or as chemical precipitates. There are two types of sedimentary rocks Clastic and Chemical Clastic sedimentary rocks form when existing parent rock material is weathered, fragmented, transported, and deposited in layers that compact,
Chalk is a soft, white, porous, sedimentary carbonate rock.It is a form of limestone composed of the mineral calcite and originally formed deep under the sea by the compression of microscopic plankton that had settled to the sea floor.Chalk is common throughout Western Europe, where deposits underlie parts of France, and steep cliffs are often seen where they meet the sea in places such as the ...
