Global Warming and Carbon Capture Quiz

What is the primary purpose of Carbon Capture and Storage (CCS)?

• To increase the efficiency of power plants

• To reduce emissions of carbon dioxide

• To generate more electricity

• To trap heat in the atmosphere

What chemical process is used in CCS to separate CO2 from other gases?

• The gases are sprayed with a chemical that attaches to CO2

• The gases are cooled to condense CO2

• The gases are dissolved in water

• The gases are filtered through a membrane

What happens to CO2 after it is captured in a CCS system?

• It is converted into oxygen

• It is injected deep underground

• It is stored in tanks above ground

• It is released back into the atmosphere

Why has CCS technology been slow to be adopted?

• It is not effective in reducing CO2

• It is expensive and reduces electrical output

• It requires too much land

• It is too simple to implement

What natural phenomenon causes CO2 levels to fluctuate annually?

• Volcanic eruptions

• Seasonal changes in vegetation

• Animal migration

• Ocean currents

What is the significance of the ice core samples mentioned in the text?

• They reveal past CO2 levels and temperatures

• They provide evidence of ancient civilizations

• They indicate the age of the Earth

• They show the history of volcanic eruptions

What is the relationship between CO2 levels and temperature according to the text?

• CO2 levels and temperature are unrelated

• Temperature changes cause CO2 levels to drop

• Higher CO2 levels lead to higher temperatures

• Higher CO2 levels lead to lower temperatures

What is the current trend in CO2 levels as described in the text?

• CO2 levels are increasing

• CO2 levels fluctuate randomly

• CO2 levels are stable

• CO2 levels are decreasing

What impact does the melting of glaciers have on water supply?

• It has no impact on water supply

• It causes a serious shortage of drinking water

• It only affects water supply in Antarctica

• It increases the availability of fresh water

What historical CO2 level has never been exceeded until recent times?

• 200 parts per million

• 300 parts per million

• 400 parts per million

• 500 parts per million
