- In what two ways does deforestation contribute to air pollution?

Answer 1

@tanya123.... need ur help to find the answer, can u help me a bit...?

Answer 2

@tanya123....u got to tell me how, after reading this...

Ozone forms readily when sunlight strikes oxygen, so it is naturally present in our oxygen-rich atmosphere. In the upper atmosphere, ultraviolet light from the sun strikes the two atoms of molecular oxygen (O2) and splits them into single atoms. Those individual atoms each combine with another molecule of two-atom oxygen to make a three-atom molecule, which is ozone (O3). Most of this ozone converts readily back to oxygen, but a small amount of ozone persists.

Another ozone-forming process takes place in the lower atmosphere, where chemicals emitted from industrial processes, vehicle exhaust, and other products of fossil fuel combustion form ozone through a more complex series of chemical reactions. As concentrations of these pollutants involved in ozone formation (precursors of ozone) increase with industrialization and vehicle traffic, ozone concentrations increase at ground level where we breathe.

Answer 3

@tanya123 Deforestation can be done either by cutting down trees or burning them, so if it's in the case of burning down trees, the smoke and harmful gases produced leads to the pollution.

Deforestation also impacts air quality in two major ways. As a result of the reduction in plant biomass, the total volume of oxygen released by plants during photosynthesis is reduced. Carbon dioxide that is normally cycled by plants builds up in the atmosphere. Carbon dioxide is considered a greenhouse gas and a contributor to global warming.

hope that works.....
