Geology exam 2 review

The troposphere is the layer of earth's atmosphere closest to the surface and contains moving air responsible for weather.

• True

• False

Ozone in the troposphere is good while ozone in the stratosphere is bad.

• True

• False

What causes the thinning of the ozone layer in the stratosphere?

• extremely warm weather in the summer months breaks apart the ozone molecule

• cold weather in the winter months breaks apart the ozone molecules

• emissions from power plants react with the ozone molecule breaking it down

• chlorine atoms from CFCs break apart the ozone molecules in a reaction with UV rays

Which of the following are non-point source pollutants?

• auto emissions

• airplane emissions

• mining operation

• fossil fuel power plant

• acid rain

Carbon Monoxide is one of the six criteria pollutants covered by the Clean Air Act.

• True

• False

Smog is generally worse in urban areas.

• True

• False

Indoor air pollution contains a much small concentration of toxic pollutants than outdoor air pollution.

• True

• False

Which substances are the major contributors in the formation of acid rain?

• NOx and SOx

• carbon monoxide and carbon dioxide

• particulates and ozone

• lead and carbon monoxide

The Clean Air Act has been fairly successful - reducing harmful air pollution from the 6 criteria pollutants over the last few decades.

• True

• False

Where do non-natural VOCs (volatile organic compounds) come from?

• the breakdown of ozone

• synthetic chemicals and products

• plants

• breakdown of smog
