Carbon released by burning fossil fuels contributes to what effect in the atmosphere? A. shielding effect B. greenhouse effect C. smog effect D. cloud effect
B. greenhouse effect
Burning of fossil fuels, such as oil, releases carbon into the atmosphere. This carbon must be cycled - removed from the atmosphere - back into living organisms, or it stays in the atmosphere. Increased carbon in the atmosphere contributes to the greenhouse effect on Earth.
