sneaker online shop sneaker online shop Answers on Ozone

Ozone: Why cant we just fill in the ozone hole with manmade ozone?

As someone mentioned, the ozone layer is not a static system where the ozone just sits around. Ozone is continuously formed and destroyed by light from the sun and chemical reactions. Light from the sun at one set of wavelengths initiates chemical reactions that cause the formation of ozone. Light from the sun at a different set of wavelengths destroys ozone. Additional chemical reactions destroy ozone such as from CFCs, but also other naturally occurring chemical species such as NO. The overall competition between these processes is what creates a laye sneaker online shop r of higher ozone concentrations in the upper atmosphere.

A bathtub is a pretty good, if incomplete, metaphor for the process. On one hand, the bathtub is constantly being filled from reactions that produce ozone. On the other hand, other reacti sneaker online shop ons drain ozone from the bath tub. Normally, because ozone is being added to the tub faster than it is drained out by chemical reactions, ozone builds up.

As CFCs leaked into the atmosphere, their overall chemical reactions acted as if the bathtub had a bigger drain. As such, ozone tub started to be drained faster without a change in the rate that it was being filled. This lead to a lower level of ozone in the bathtub compared to previously. So, if someone added a bunch of manmade ozone to the ozone layer technical difficulties aside, the amount of ozone would increase only temporarily to be removed by the bigger drain created by CFCs.

Ozone: If we are able to reduce the greenhouse gases, will the ozone l sneaker online shop ayer be recreated?

The hole in the ozone layer is caused by chlorine in the atmosphere, not by greenhouse gases. CFCs are the manmade chemicals responsible for increase of chlorine in atmosphere and are themselves potent greenhouse gases. So, decreasing emissions of CFCs helps both the ozone layer recover and slightly reduce the increase in higher average temperatures at the Earth surface. Reducing emissions of CO2, the most important greenhouse gas behind climate change, will not have too much impact on the ozone layer. However, N2O, the third most important greenhouse gas, also increases NOx in the ozone layer, which is another chemical that leads to more ozone depletion. Decreasing N2O emissions thus will help slow climate change and ozone depletion. That a lot easier said than done though because N2O is emitted by many different sources. sneaker online shop
