Another interesting chemical interaction is how lightning causes rain to be more nourishing to plants. It separates the nitrogen from the air, which combines with oxygen to form nitrogen dioxide. "Nitrogen dioxide dissolves in water, creating nitric acid, which forms nitrates. The nitrates fall to the ground in raindrops and seep into the soil in a form that can be absorbed by plants." --- https://wxguys.ssec.wisc.edu/2018/07/09/lightning/
