More nitrogen in the atmosphere leads to NITRIC ACID RAIN.
When nitrogenous fertilizers are used on the farm, some gases are released into the atmosphere including nitric oxide. These gases rises up into the atmosphere, mix with rainfall.

The dissolving power of water is very important for life on Earth. Wherever water goes, it carries dissolved chemicals, minerals, and nutrients that are used to support living things. Because of their polarity, water molecules<span> are strongly attracted to one another, which gives water a high </span>surface tension<span>.</span>
