... dioxide, methane and carbon monoxide. These gasses are released into the atmosphere where they are incorporated into the relief cycle. The carbon dioxide in the rain gives it an acidic pH, hence the name acid rain. When the rainfalls the acid dissolves into the soil and washes out all the nutrients such as calcium and magnesium, it also washes out such chemicals as aluminium, which is highly toxic. All the gasses in the atmosphere build up to form a thick blanket, which sits in the upper atmosphere. This blanket lets light rays into the atmosphere but does not let all out. Acting as insulation, this makes the temperature rise very little. If this continues then the temperature will rise enough to melt the polar icecaps. This will release thousands of tons of water into the oceans of the world causing sea levels to rise dramatically. If this happens all the low ...
