Which of the following can be natural causes of climate change?
changes in the amount of energy released by the sun
changes in the path of Earth's orbit around the sun
changes in the tilt of Earth's axis
volcanic eruptions
All of the above.
The greenhouse effect refers to _______.
the warming of Earth due to human activities
a natural process that keeps Earth's atmosphere warm
environmental change
a particularly strong ocean current that effects Earth's weather
Which of the following is considered a greenhouse gas?
Sodium Chloride
Methane and Carbon Dioxide
Oxygen
Nitrogen
The main greenhouse gas produced by human use of fossil fuels is _______.
sulfate aerosols
nitrous oxide, N2O
sulfur dioxide, SO2
carbon dioxide, CO2
The powerful greenhouse gas produced by livestock as a metabolic waste product and fossil fuel extraction is
nitrogen oxides
methane, CH4
propane, C3H8
halocarbon and fluorocarbon gases
Increasing greenhouse gases in the atmosphere contributes significantly to
ozone depletion
tectonic plate shifting
global temperate decrease
global temperature increase
Within the carbon cycle, anything that absorbs more carbon from the atmosphere than it releases is called a
carbon sink
carbon source
Which of the following function as carbon SINKS within the carbon cycle?
Oceans, Forests and other plant growth
Burning of fossil fuels
Deforestation
Volcanic eruptions
Deforestation leads to an increase in carbon dioxide because
trees are carbon sources because of photosynthesis
trees are carbon sinks because of photosynthesis
burning of wood releases oxygen which reacts in the atmosphere to form carbon dioxide
all of the above
What is the cause of the trend in the graph above beginning around the year 1750?
global temperature increase
increase in fossil fuel emissions beginning with the industrial revolution
increased volcanic eruptions beginning around 1750 and continuing today
decreased use of oil and gas products following the establishment of the United States
Which of the statements below is true concerning the data from the graph below.
The rate of temperature increase has slowed since about 1975 as carbon dioxide levels in the atmosphere has decreased.
Global temperature has risen since 1900 but remained constant since about 1990 when carbon dioxide levels increased.
A sharp rise in global temperature is related to rising carbon dioxide levels in the atmosphere.
None of the above are true statements.
Compared to historical trends, what is different about recent climate change?
It's occurring faster
It's a warming trend
It's affecting only plants and animals
It's caused by solar changes
Scientific evidence strongly suggests that increasing carbon dioxide in the atmosphere contributes significantly to
photochemical smog
ozone depletion
acid rain
global warming
Which of the following statements about the trend in global temperature is true?
There is a connection between the greenhouse effect and global warming
Data does not support the reported increase in global temperature.
While the global average air temperature is increasing, the ocean temperature is actually decreasing.
The rise in global temperature is positive but is has slowed down over the last 15 years.
Why would global warming lead to an increase in sea level?
Sea ice would melt
Land-based ice would melt
Earth's tectonic plates will expand
all of the above
Which of the following statements is likely to NOT be a possible result of global climate change?
Stronger tropical storms and hurricanes
Rising sea levels
Increased occurrences of extreme weather conditions such as drought
Decreased incidence of insect born diseases
Living plants remove ____________________ from the atmosphere.
carbon dioxide, CO2
nitrogen oxides
nitrous oxide, N2O
propane, C3H8
