Fujita Scale (F Scale) A scale of wind damage intensity in which wind speeds are inferred from an analysis of wind damage:
F0 (weak): 40- 72 mph, light damage.
Most of these emissions, about 82 percent, are from burning fossil fuels to generate electricity and power our cars.
beta particle emission as inferred from measurements on a
dry sample.

'Acid rain' Rain with a very low pH (often below 4.0) resulting from emissions to the atmosphere of oxides of sulfur and nitrogen. Adaptation A confusing word used to mean quite different things.
If they plant enough trees, that offsets their emissions, and the net balance of emissions is zero. It is not a matter of planting trees as a virtuous religious act to atone for the sin of emitting. It literally undoes the harm.
Airborne particulates include windblown dust, emissions from industrial processes, smoke from the burning of wood and coal, and the exhaust of motor vehicles.

The largest source of mercury emissions is Coal-burning power plants, which account for 40 percent of all domestic human-caused mercury emissions. Mercury in the air eventually settles into water or onto land where it can be washed into water.
Burning fossil fuels and generating waste lead to the emissions of several kinds of greenhouse gases, each of which has different heat-trapping qualities. For example, a pound of methane traps 25 times more heat than a pound of carbon dioxide.
Acid Rain occurs when pollutants such as nitrogen oxides and sulphur dioxide from power plant emissions, metal smelting, motor vehicles and industry, combine with water in the atmosphere to form droplets of very weak acid.
