How do zombie fires relate to permafrost?

• They occur in areas without permafrost

• They burn under ice throughout the winter

• They are unrelated to permafrost

• They only occur in tropical regions

Why are zombie fires becoming more common?

• Due to increased rainfall

• Due to the thawing of permafrost

• Due to less vegetation

• Due to volcanic activity

Explain the process of energy flow from peat to the air during a zombie fire.

• Peat absorbs energy from the air and releases it as light

• Peat releases energy as heat and carbon dioxide into the air

• Peat absorbs carbon dioxide and releases oxygen

• Peat releases water vapor and cools the air

Analyze the environmental impact of burning peat in terms of carbon emissions.

• It reduces carbon emissions by absorbing CO2

• It increases carbon emissions by releasing CO2

• It has no impact on carbon emissions

• It decreases carbon emissions by releasing oxygen

Evaluate the role of peat in the carbon cycle and its implications for climate change.

• Peat acts as a carbon sink, reducing atmospheric CO2

• Peat releases CO2, contributing to climate change

• Peat has no role in the carbon cycle

• Peat increases oxygen levels, mitigating climate change

When drawing energy transfer models,

• energy releases matter

• matter releases energy

• the energy released is always less than the energy absorbed

• the energy released is always greater than the energy absorbed
