Gypsum forms from the deposition of ocean ... chalk, soft, fine-grained, easily pulverized, white-to-grayish variety of limestone. Chalk is composed of the shells of such minute marine organisms as foraminifera, coccoliths, and rhabdoliths. The purest varieties contain up to 99 percent calcium carbonate in the form of the mineral calcite.Chalk is formed from lime mud, which accumulates on the sea floor in the right conditions. This is then transformed into rock by geological processes: as more sediment builds up on top, and as the sea floor subsides, the lime mud is subjected to heat and pressure which removes the water and compacts the sediment into rock.Earth Sciences. Earth Sciences questions and answers. Chalk forms from ________. the hard parts of microscopic organisms that accumulate on the sea floor magnesium rich fluids that chemically alter limestone bearing reefs direct precipitation from seawater evaporation of magnesium rich waters. Chalk is formed out of superfine sediment called ‘ooze’. The formation of chalk starts with the death of the shells of marine animals, called ‘foraminifera’, marine algae, or other organisms that live at the bottom of the ocean, or in the waters above.
