Which of the following best describes albedo?

• Albedo measures how much light is absorbed, ranging from 0 (reflective) to 1 (absorbs all light)

• Albedo measures how much light is reflected, ranging from 0 (absorbs all light) to 1 (reflective)

• Albedo measures the amount of accordions in a song (named after Weird Al)

• Albedo measures the difference in wavelength of radiation hitting the Earth and emitted by the Earth

Is Earth's energy budget currently balanced?

• No because some countries are using more than carbon than others

• No because more light is being absorbed than emitted and reflected

• Yes, because of the law of conservation of energy

• Yes, the amount of energy absorbed by the Earth is the same as the amount being emitted

• Negative feedback loop

• Neutral feedback loop

• Heat stroke

Which of the following is most likely a carbon sink?

• A factory burning coal

• A dairy farm

• A forest

• A volcano erupting

Which of the following is not true about greenhouse gasses?

• Carbon dioxide is a greenhouse gas that is produced by animals breathing

• Methane is a greenhouse gas produced by livestock and melting permafrost

• Nitrogen gas (N2) is a major greenhouse gas

• Greenhouse gasses are important for keeping Earth's energy budget balanced for life to survive

Which of the following is most true about land use?

• Land use has not changed significantly in the past 100 years

• Land use has shifted to include more cities and farm land, leading to deforestation

• Land use has become more focused on preservation, and cities have become smaller

• Farms have become more efficient, so farmland has been converted back to forests
