This resource turns feedback loops in the carbon into a complete, ready to use review for Grade 9-12 earth science, covering the same NGSS standard from three different angles.

Sample questions include "What role does forest loss play in carbon feedback mechanisms?", "What effect does permafrost melt have on atmospheric CO₂ levels?", and "What is a potential consequence of increased atmospheric CO₂ due to permafrost melt?"
