Answer 1

Answer:

1) Yes,in form of sulfur dioxide (SO2) and nitrogen oxides (NOX).

2) The process by which soil and rock is removed from one area of the Earth through natural causes such as wind, water, and ice and transported elsewhere is called erosion.

3)The SO2 and NOX react with water, oxygen and other chemicals to form sulfuric and nitric acids. These then mix with water and other materials before falling to the ground.

4)Well water is a common water system used in rural homes and waterfront properties. It's water found deep in the ground, beneath layers of rock and soil that act as a natural filter for contaminates. Because of this, the water tends to have a higher mineral content than municipal water.
