Question

If large amounts of permafrost begin to melt, what impact would this have on the carbon cycle?(1 point) Responses Carbon dioxide and methane would be released, increasing atmospheric carbon levels. Carbon dioxide and methane would be released, increasing atmospheric carbon levels. Carbon would be permanently trapped in newly formed ice, reducing CO₂ levels. Carbon would be permanently trapped in newly formed ice, reducing CO₂ levels. Melting permafrost would create new fossil fuels, lowering carbon levels. Melting permafrost would create new fossil fuels, lowering carbon levels. The carbon cycle would stop because carbon could no longer be exchanged between reservoirs.

Answer 1

The correct response is: **Carbon dioxide and methane would be released, increasing atmospheric carbon levels.**

As permafrost melts, it releases stored greenhouse gases like carbon dioxide and methane into the atmosphere, contributing to climate change and increasing atmospheric carbon levels.
