The main component of chalk is calcium carbonate (CaCO 3 ), a form of limestone. Limestone deposits develop as coccoliths (minute calcareous plates created by the decomposition of plankton skeletons) accumulate, forming sedimentary layers.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.May 17, 2021 · The PM exposure study had shown that DL-1 and DL-2 produced lesser PM 10 and PM 2.5 when compared with the other brands, but emitted more PM 1.
