used to determine if this is a natural earth cycle or not

Question 16

earth glow

Answer 16

the light emitted from all objects in the universe. the color of the light changes with temperature, the infrared light carries energy away from the earth into space
CO2 bonds with earth glow and changes to heat energy which gets absorbed in the oceans intensifying the hydrologic cycle.
