Water, Carbon, and Climate Change Quiz

Which of the following is NOT mentioned as a water store in the text?

• Atmosphere

• Oceans

• Glaciers

• Volcanoes

What is the primary role of water in ecosystems?

• To provide a habitat for fish

• To carry and recycle nutrients

• To regulate temperature

• To erode landscapes

How do plants primarily interact with the carbon cycle?

• Through respiration

• Through decomposition

• Through photosynthesis

• Through transpiration

What is a positive feedback loop in the context of climate change?

• A process that reverses climate change

• A cycle that maintains equilibrium

• A disturbance that a system cannot adapt to

• A human intervention to reduce emissions

Which gas is NOT mentioned as being released when permafrost thaws?

• Carbon dioxide

• Methane

• Oxygen

• Water vapour

What is the primary cause of permafrost melting according to the text?

• Natural climate cycles

• Human-induced climate change

• Increased volcanic activity

• Changes in Earth's orbit

Which of the following is a potential positive impact of Arctic warming?

• Increased greenhouse gas emissions

• Loss of permafrost

• Expansion of farming to higher latitudes

• Rising sea levels

What happens to the active layer of permafrost as surface temperatures rise?

• It becomes shallower

• It increases in depth

• It disappears completely

• It turns into bedrock

How does increased vegetation in warmer Arctic environments affect carbon dioxide levels?

• It increases atmospheric CO₂

• It has no effect on CO₂ levels

• It takes in more CO₂ from the atmosphere

• It releases more CO₂ through decomposition

Which of the following is an example of a negative feedback loop in climate systems?

• Melting permafrost releasing greenhouse gases

• Increased plant growth absorbing more CO₂

• Rising temperatures causing more water vapour in the atmosphere

• Melting ice reducing Earth's albedo
