What is Methane produced by?
Combustion & Vehicle Exhaust
Anaerobic Respiration & Methanogenic Bacteria
Evaporation & Transpiration
Anaerobic Respiration & Combustion
Which are Greenhouse Gases? Select all of the following that apply.
Hydrogen
Nitrous Oxide
Methane
Water Vapor
Nitrogen
By which mechanism do greenhouse gases contribute to global warming?
They absorb higher amounts of short wave radiation caused by increased combustion of fossilized organic matter.
Their higher concentration absorbs more long wave radiation coming from the Sun.
Short wave radiation emitted from the Earth's surface increases with their concentration.
They absorb higher amounts of long wave radiation emitted from the Earth's surface as their concentration increases.
If the concentration of Greenhouse Gases rises, then...
more heat will be retained.
more heat will be released.
more water vapor will be retained.
more nitrogen will be released.
What can an increase in the greenhouse effect result in?
increase in the amount of alien/invasive species.
the disruption of ecological niches due to competition
decrease in the amount of food (prey)
all of the above
What is Biomass?
a significant change in the Earth's climate, including changes in weather patterns, the oceans, ice and snow, and ecosystems around the world.
a marine ridge or reef consisting of coral and other organic material consolidated into limestone.
material that comes from living things, including trees, crops, grasses, and animals and animal waste
a type of fuel produced from plants or other forms of biomass. Examples of biofuels include ethanol, biodiesel, and biogas.
What is the correlation between global temperature and C02 concentrations?
There is no correlation between the two.
The higher the temperature, the less c02 is present.
The higher the temperature, the more C02 is present.
The lower the temperature, the more C02 is present.
Why are ice cores useful to scientists?
They are used to measure the Earth's current temperature.
They allow for scientists to measure the amount of radiation is being received by the Earth.
They can be used to measure to the rising ocean levels over certain periods of time.
They allow for scientists to see changes in temperature and the amount of C02 in the atmosphere at the time the ice was formed.
What do records from the twentieth and twenty-first century show about the concentration of carbon dioxide in the atmosphere?
An upward trend with no annual fluctuations
An upward trend with annual fluctuations
Annual fluctuations but no overall trend
Random fluctuations and no overall trend
Which property of a gas means that it is classed as a greenhouse gas?
They trap some of the long-wave radiation emitted by the Earth’s surface
They prevent short-wave radiation from reaching the Earth’s surface
They dissolve in rainwater to produce acid rain
They are only produced by human activity
What contributes to the enhanced greenhouse effect?
Methane from agricultural sources
Ozone from violent thunderstorms
Carbon particles in diesel engine exhaust
Carbon dioxide from active volcanoes
Distinguish between short wave radiation and long wave radiation.
Both short wave radiation and long wave radiation are reemitted as heat back into the atmosphere
Long wave radiation comes directly from the sun to be absorbed by the atmosphere while short radiation comes from the sun and is reemitted as heat
Short wave radiation comes directly from the sun to be absorbed by the atmosphere while long radiation comes from the sun and is reemitted as heat
Both short wave radiation and long wave radiation are absorbed upon reaching earth's atmosphere
Which of the following increase the effect of greenhouse gases? Select all that apply.
Burning of fossil fuels
Methane from agriculture
Food waste
Car exhaust
Evaporation
Which of the following is NOT a potential problem associated with climate change?
The melting of ice habitats
Desertification
Extreme growth in species
Destruction of food webs
What is a potential consequence of the rise in global temperatures on the Arctic ecosystem?
Decreased success of pest species
Increased exposure to UV light
Increase in the ice habitat available to polar bears
Increased rate of decomposition of detritus
In decreasing order, which greenhouse gases have the largest warming effect within the atmosphere?
Carbon dioxide, methane, nitrous oxide, water vapor
Water vapor, carbon dioxide, methane, nitrous oxide
Methane, carbon dioxide, water vapor, nitrous oxide
Nitrous oxide, methane, carbon dioxide, water vapor
What is the effect of global warming on the ocean?
As the amount of carbon dioxide absorbed by the ocean rises, the pH of the sea surface water has decreased.
The ocean absorbs water vapor, which decreases the amount of carbonate ions needed for coral reefs to survive.
Methane absorbed by the ocean causes sea levels to decrease, which causes the pCO₂ of the ocean to decrease as well.
Because the ocean absorbs 75% of carbon from the atmosphere, this abundance of carbonate ions will be harmful to ocean organisms.
Which of the following is true?
There is a strong correlation between annual fluctuations of temperatures and human emissions.
There is a strong correlation between human emissions and atmospheric levels of carbon dioxide.
There is a weak correlation between temperature variation and human emissions.
There is no correlation between human emissions and atmospheric levels of carbon dioxide.
Which two factors determine the warming impact of a greenhouse gas? Select the two answer choices that apply.
Methane's ability to cause significantly less warming per molecule than carbon dioxide.
The concentration of the gas in the atmosphere.
Carbon dioxide's temporary persistence in the atmosphere.
How readily the gas absorbs long-wave radiation.
Water vapor's slow entrance into the atmosphere.
