How does air pollution affect plants hi this is for my 6th grade science project. please reply ASAP?

1 Air pollution can affect soil moisture levels. It's responsible for yo-yo moisture and temperature extremes. For example, too high temperatures can be accompanied by high rates of evaporation from the air, and evapotranspiration from the soil.

Groundwater is recharged by moisture infiltrating into, and percolating through, the soil. Our supplies of below-ground water, ka groundwater, can run low. A plant's roots grow horizontally across, and vertically down, in response to soil moisture levels.

If the levels aren't correct, then roots don't grow properly. 2 Air pollution can affect salt levels in the soil. Too much salt in the soil is toxic to plants.

It also causes the soil surface to compact, and crust over. 3 Air pollution can affect nutrient levels in the soil. Healthy plants and soils need 16-17 nutrients.

Incorrect amounts of any one nutrient throws the entire nutrient chain off. Air pollution tends to make large amounts of nitrogen and sulfur available to soil and ... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
