AP Unit 7

A thermal inversion, which can lead to serious pollution events, occurs when

• warm air close to the surface is blanketed by a layer of cool air that traps pollutants.

• cool air close to the surface is blanketed by a layer of warm air that traps pollutants

• warm air rises, taking pollutants with it.

• cool air rises, taking the pollutants with it

NGSS.MS-ESS3-4

One of the effects of bicarbonate (HCO₃) that leaches from limestone soils into surrounding lakes is to:

• slightly increase the acidity of the water

• greatly increase the acidity of the water

• buffer the effects of acid rain

• have no effect on the pH of the lake water

NGSS.MS-PS1-2

Which of the following is NOT classified as a primary pollutant?  

• Carbon Monoxide

• Nitrogen Oxides

• Sulfur Dioxides

• Ozone

Ozone is a natural component of the Earth’s stratosphere as well as an element of photochemical smog. Ozone also can be an indoor air pollutant. Sources of ozone in homes or offices include:

•  combustion of fossil fuels

• household solvents and cleaning fluids

• photocopying machines, printers, and other high-voltage electrical equipment  

• electrolysis of tap water
