Eccentricity influences the shape of the Earth’s orbit around the sun. As eccentricity increases, the shape of Earth’s orbit becomes more…
Circular
Oval-shaped
Square
None of the above
Which of the following is NOT an accurate role that greenhouse gases (such as carbon dioxide and methane) have in Earth's climate system?
help prevent the earth from cooling substantially each night
allows for light (short-wavelength) energy to travel through the atmosphere.
help trap and hold thermal (short-wavelength) energy in the atmosphere
helps keep the Earth at a moderate 59 degrees Fahrenheit.
Which of the following is not a greenhouse gas?
carbon dioxide
ethane
methane

How does the average annual surface temperature compare from latitude to latitude?
As latitude increases, the average annual surface temperature decreases.
As latitude increases, the average annual surface temperature increases.
As latitude increases, the average annual surface temperature remains the same.
There is no relationship between temperature and latitude
Which statement best explains why location B and location E receive low average yearly precipitation?
What impact do forest fires have on albedo?
Forest fires increase albedo because of all of the soot
Forest fires decrease albedo because of all of the soot
Forest fires increase albedo because they're bright
Forest fires decrease albedo because they're bright
What impacts do forest fires have on greenhouse gases?
Several greenhouse gases are released into the atmosphere by burning trees/plants
Greenhouse gases in the atmosphere are reduced from forest fires
Burnt trees/plants can't remove CO2 from the air to make O2, so more CO2 stays in the atmosphere
Forest fires have no impact on greenhouse gases
Carbon enters the soil through dead plant or animal matter.
Decomposition
Respiration
Photosynthesis
Diffusion

carbon sink
carbon source
Within the carbon cycle, anything that releases more carbon into the atmosphere than it absorbs.
carbon sink
carbon source
Forests are carbon sinks because they remove carbon dioxide from the atmosphere through ____________.
combustion
respiration
photosynthesis
decomposition
