Chlorine is abanduntful in lithosphere, and it is estimated to be about 0.045%. Its strong chemical affinity for the other elements, it never occurs in the free state, except as a minor organization of the gaseous output from volcanic eruptions. | Chlorine is abanduntful in lithosphere, and it is estimated to be about 0.045%.

Chlorine is consisted by the most common minerals; rock salt or halite(NaCl), sylvite(KCl) and carnallite(MgCl12.KCl.6H20). | Chlorine is consisted by the most common minerals; rock salt or halite(NaCl), sylvite(KCl) and carnallite(MgCl12.KCl.6H20). | ||
Chlorine salts are liquefy in the hydrosphere instead of being spread out in the lithosphere. | Chlorine salts are liquefy in the hydrosphere instead of being spread out in the lithosphere. NaCl, sodium chloride is the most commom element of alkali metals in the hydrosphere as well as in the lithosphere. Thus, it's named commom salt. The average concentration in seawater is approximately 2,6%. Table salt is unreplaceable function in human diet and the uneven distribution of its deposits over the earth's crust has played an original role in conditioning the pattern of civilization in time and space. | ||
