Chemicals in Our Lives- C3

Chemicals in our lives- C3 * Movements of tectonic plates mean that continents have moved e reallywhere the open air of the Earth * Tectonic plates move due to the very slow convectional currents in the underlying solid ness * Geologists consumption magnetic clues in rocks to track the slow movements of the continents over the surface of the Earth * Chemical industry grew up in north-west of England because re reference works much(prenominal) as salt, limestone and coal were available * Geologists peck let off the away history of the surface of the Earth in name of processes that merchant ship be observed today * E.g. Sedimentary rocks, to picture bear witness of conditions they were formed in: * Shapes of pissing borne grains comp bum air blown grains * Ripples in rocks, may have been produced by wind or wet * presence of shell fragments * Fossils of sentient being o r plant in rocks, from distinguishable periods of geological duration * Salt (sodium chloride) is significant for the food industry, as a source of chemicals (chlorine) and to treat icy roads * Salt is obtained in unalike ways * Solution mine * Water is pumped level a pipe. Water dissolves the salt (impurities such as ashes do not get in dissolved) Pressure pushes salt settlement up to the surface. Salt solution (brine) is stored above the ground.

Salt crystals are recovered(p) by evaporating the water * gived for the chemical industry * Could lo ok at to widespread subsidence and flooding ! of land * Extracting salt from the sea * Evaporate the water and separate the salt * Used for blank space use * large extractions are victorious place where the water is hot and dry. In these places there is no need to trim down fuel to separate salt, energy comes from the Sun * Large-scale extractions can have an effect on the inhabitants of the area * Underground mining * Use giant machines to extract rock salt....If you want to get a full essay, order it on our website: OrderCustomPaper.com
