APES Chapter 19 QUIZ

The Greenhouse gas with the highest greenhouse warming potential is

• carbon dioxide

• methane

• water vapor

• chlorofluorocarbon

• nitrous oxide

Methane is naturally produced by

• decomposition

• volcanic eruptions

• denitrification

• evapotranspiration

• forest fires

The greenhouse effect is due to

• the absorption and reradiation of infrared radiation by the atmosphere

• the reflection of ultraviolet radiation by the atmosphere

• the absorption of ultraviolet radiation by the atmosphere

• the reflection of infrared radiation from Earth's surface

• the absorption of ultraviolet radiation by Earth

Most nitrous oxide emissions are from

• fossil fuel combustion

• agricultural practices

• refrigerants

• deforestation

• industrial processes

Particulate matter can increase global warming by

• reacting with chlorofluorocarbons

• reducing surface absorption of ultraviolet radiation

• producing additional nitrous oxides

• reflecting radiation

• lowering surface albedo

What is the evidence that solar radiation is less important to global warming than the increase in greenhouse gases?

• temperatures have increased more in the summer than in winter

• temperatures have increased more in the winter than in summer

• temperature increases have been uneven across the globe

• there is a historic correlation of CO₂ and temperature

• There is a lack of temperature change in some areas

If the annual rate of CO₂ increase is 1.5ppm and the concentration in 2010 is 390ppm, what concentration would you expect in 2100?

• 420 ppm

• 480 ppm

• 505 ppm

• 525 ppm

• 540 ppm

How much has the average global temperature increased in the last 120 years?

• 0.6°F

• 1.0°F

• 1.4°F

• 2.7°F

• 3.2°F

Which data are used to estimate historic temperatures and carbon dioxide concentrations?

I. Marine organism fossils

II. air trapped in ice

III. glacier depth

• I only

• I and II only

• I and III only

• II and III only

• I, II and III

Which is an example of a negative feedback?

• higher air temperatures cause increased ocean evaporation

• higher air temperatures cause increased decomposition in soils

• lower concentrations of CO₂ cause increased absorption of oceanic CO₂

• low albedo causes decreased reflection of sunlight

• higher CO₂ concentrations cause increased photosynthesis
