* 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 mantle
* 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 resources much(prenominal) as salt, limestone and coal were available
* Geologists peck explain the away history of the surface of the Earth in terms of processes that can be observed today
* E.g. Sedimentary rocks, to find bear witness of conditions they were formed in:
* Shapes of pissing borne grains comp bed air blown grains
* Ripples in rocks, may have been produced by wind or water
* presence of shell fragments
* Fossils of animal or plant in rocks, from distinguishable periods of geological time
* Salt (sodium chloride) is significant for the food industry, as a source of chemicals (chlorine) and to treat icy roads
* Salt is obtained in different ways
* Solution mining
* Water is pumped floor a pipe. Water dissolves the salt (impurities such as ashes do not get dissolved) Pressure pushes salt settlement up to the surface. Salt solution (brine) is stored above the ground.



Salt crystals are recovered by evaporating the water
* gived for the chemical industry
* Could look at to widespread subsidence and flooding of land

* Extracting salt from the sea
* Evaporate the water and separate the salt
* Used for home use
* large extractions are victorious place where the water is hot and dry. In these places there is no need to burn 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: Orderessay
