Chat Moss it for agriculture. About of degraded bog remain, with of undamaged peat deposits in four former peat extraction sites. The peat varies in depth between and . The main bog mosses found in the peat of Chat Moss are "Sphagnum cuspidatum", "S. imbricatum", and "S. acutifolia". The peat up to about from the surface is mainly humidified "S. acutifolia", with fresher "S. imbricatum" peat nearer the surface. A area of Chat Moss, to the north of the Liverpool–Manchester railway line, notified as Astley & Bedford Mosses, was designated a Site of Special Scientific Interest in 1989. Astley & Bedford Mosses,
Oxy-fuel welding and cutting is what chemically combines with the fuel to produce the heat for welding. This is called 'oxidation', but the more specific and more commonly used term in this context is 'combustion'. In the case of hydrogen, the product of combustion is simply water. For the other hydrocarbon fuels, water and carbon dioxide are produced. The heat is released because the molecules of the products of combustion have a lower energy state than the molecules of the fuel and oxygen. In oxy-fuel cutting, oxidation of the metal being cut (typically iron) produces nearly all of the heat required to "burn" through
