| chalk (A soft, pure, earthy, fine-textured, usually white to light gray or buff limestone of marine origin, consisting almost wholly (90-99%) of calcite, formed mainly by shallow-water accumulation of calcareous tests of floating microorganisms (chiefly foraminifers) and of comminuted remains of calcareous algae (such as cocoliths and rhabdoliths), set in a structureless matrix of very finely crystalline calcite. The rock is porous, somewhat friable, and only slightly coherent. It may include the remains of bottom-dwelling forms (e.g. ammonites, echinoderms, and pelecypods), and nodules of chert and pyrite. The best known and most widespread chalks are of Cretaceous age, such as those exposed in cliffs on both sides of the English Channel) | krīts | |

| chemical engineering (The branch of engineering concerned with industrial manufacture of chemical products. It is a discipline in which the principles of mathematical, physical and natural sciences are used to solve problems in applied chemistry. Chemical engineers design, develop, and optimise processes and plants, operate them, manage personnel and capital, and conduct research necessary for new developments. Through their efforts, new petroleum products, plastics, agricultural chemicals, house-hold products, pharmaceuticals, electronic and advanced materials, photographic materials, chemical and biological compounds, various food and other products evolve) | ķīmijas inženierzinātne |
