Atmospheric CO2 concentration and Antarctic temperature are directly correlated over the past 800,000 years.

Which of the following best describes the energy resource used most often for heating and cooking in less developed countries?

Biomass is the predominant fuel source because it is easily obtained locally.

Which of the following equations best represents the chemical changes that occur during ocean acidification?

CO2+H2O→2H++CO32−

Which of the following resources would most likely be mined from the plant remains buried in eastern Montana during the Cretaceous

Fossil fuels such as coal

What type of gas do dams emit?

Greenhouse gasses

Nuclear power is a component of the line labeled "Other" in the graph. Why is it impossible for nuclear energy to completely replace oil and gas in the future?

Nuclear power can supply electricity, but it cannot replace other uses of oil and gas.

Which sequence of events best explains the interaction between the components of the arctic ecosystem feedback loop?

Permafrost thickness increases -> methane decreases -> global temperature increases -> permafrost thickness decreases

Which of the following best describes how electricity is generated using photovoltaic cells?'

Photons of light excite electrons that result in a flow of current.

Which of the following best explains the impact of climate change on polar regions?

Polar regions are warming more quickly than other regions because warming decreases the coverage of high-albedo ground cover like ice and snow.

Which of the following best explains the change in energy resource use?

Renewable sources replaced nonrenewable sources for electricity generation but not for transportation.

Which of the following is a natural source of atmospheric carbon dioxide?

Respiration OR decomposition of organic matter
