T10L6: Global Warming and Carbon Cycle Quiz

How is the carbon cycle similar to the water cycle?

• Both involve liquid substances falling to the Earth from the atmosphere

• Neither process works at low temperature

• Both involve the transfer of substances between animals, plants, and the Earth

• Both involve the transfer of substances between the earth and outer space

How can global warming cause sea levels to rise? Choose the best answer.

• by causing it to rain more often
• by melting glaciers and ice caps
• by increasing the number of undersea volcanic eruptions
• by creating bigger and more powerful hurricanes

Which is a natural source of greenhouse gases?

• aerosols

• deforestation

• volcanic eruptions

• burning fossil fuels

How do carbon emissions lead to global warming?

• By trapping the sun's heat in the atmosphere.

• By causing very hot volcanic eruptions.

• Rocks become richer in carbon as time goes by.

• By increasing the amount of carbon in the earth's crust

How do plants affect the air that animals and people breathe?

• Plants use oxygen from the air to make their own food

• Plants release pollution into the air

• Plants take in carbon dioxide and release oxygen

• Plants take in oxygen and release carbon dioxide

The process of plants turning carbon dioxide and water into oxygen and sugar is called

• Respiration

• Oxidation

• Photosynthesis

• Combustion

Why does cutting down trees increase global warming?

• trees soak up carbon dioxide

• trees provide shade which counteracts global warming

• trees absorbs the sun's energy without radiating back into the atmosphere

• trees drain greenhouse gases like methane from soil

How does carbon become locked inside the earth?

• Tree roots expel carbon into the soil as they grow.

• Humans use machines to pump carbon dioxide into large underground rocks.

• Rocks become richer in carbon as time goes by.

• The carbon-rich bodies of plants and animals decay into the earth after they die.

Which one of these does not add CO₂ to the atmosphere?

• cooking with gas

• planting trees

• burning wood

• riding in a bus

Why is burning fossil fuels harmful?

• they cause cancer

• They can get extremely hot

• it increases the amount of carbon dioxode/greenhouse gases in the air

• this would destroy fossils
