Front

What is a consequence of permafrost thawing due to zombie fires?

Back

Release of stored carbon dioxide.

Front

When do zombie fires typically occur?

Back

Winter.

Front

What was increased in the Arctic 10,000 years ago?

Back

Solar radiation.

Front

What method is used to detect zombie fires?

Back

Satellite imagery.

Front

What molecule is needed for cellular respiration?

Back

Glucose.

Front

Define 'permafrost'.

Back

Permafrost is a thick subsurface layer of soil that remains frozen throughout the year, occurring mainly in polar regions.

Front

What are zombie fires?

Back

Zombie fires are wildfires that smolder underground and can re-emerge after winter, often fueled by thawing permafrost.

Front

Explain the role of carbon dioxide in climate change.

Back

Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, contributing to global warming.

Front

What is the Arctic Circle?

Back

The Arctic Circle is a polar region located at approximately 66.5° North latitude, marking the southernmost point where the sun does not set on the summer solstice.

Front

How does thawing permafrost affect ecosystems?

Back

Thawing permafrost can lead to habitat loss, changes in vegetation, and increased greenhouse gas emissions.
