Describe how soil salinization occurs
Water naturally has small amounts of minerals, like salt, dissolved in it. Repeated watering leaves that salt in the soil as the water gets absorbed or evaporates.

burn the coal, use the heat to boil water into steam, use the steam to turn a turbine attached to a generator
Describe a thermal inversion
A cool air mass gets trapped under a warmer air mass, trapping pollutants with it.

primary - physical removal of large solid
secondary - biological removal of organic solids
tertiary - chemical treatment - disinfection
