SQ06 - Carbon Water & Life on Earth

What is the key component for all known life on earth?

• Water

• Carbon

• Oxygen

• Nitrogen

An important link within the carbon cycle is the ability of water to carry ​ (a)   in solution.

• CO2
• CH4
• CaCO3
• CO
• C6H12O6

What happens when carbon dioxide concentrations rise?

• Air temperatures go down

• Oceans cool down

• More water evaporates into the atmosphere

• Greenhouse heating decreases

What is the role of carbon and water in the greenhouse effect?

• Carbon and water absorb and transport each other

• Carbon and water have no role in the greenhouse effect

• Carbon and water interact to cause El Nino

• Carbon and water affect air temperature and moisture absorption

How does deforestation impact the water cycle? (Select ALL which apply.)

• Increases evapotranspiration levels

• Increases infiltration and overland flow

• Reduces precipitation levels

• Causes desertification

What is the impact of deforestation on the carbon cycle? (Select ALL which apply.)

• Increases carbon sequestration

• Reduces carbon emissions

• Turns a carbon sink into a carbon source

• Enhances the greenhouse effect

Which regions of the world are being impacted the most by climate-related issues?

• Africa and Asia

• North America and Europe

• South America and Australia

• All regions are affected by different factors, but equally impacted

What are the likely impacts of drought on affected communities?

• Increased water availability

• Improved agricultural productivity

• Food and water shortages

• Decreased risk of natural disasters

CCS follows a three stage process... put the stages in the correct order:

• Storage

• Capture

• Transporting

What can carbon capture and storage (CCS) potentially do?

• Increase CO2 emissions

• Reduce oil and gas resources

• Enhance the greenhouse effect

• Make more oil or gas available
