Question

what statement about the combustion of fossil fuels in engines and the combustion of wood from trees in large - scale forest fires is correct?
forest fires contribute to an increase in atmospheric carbon dioxide, and fossil fuel combustion absorbs co2 from the air.
fossil fuel combustion contributes to an increase in atmospheric carbon dioxide, and forest fires absorb co2 from the air.
the combustion of fossil fuels and burning wood contributes to an increase in atmospheric concentrations of carbon dioxide.
the combustion of neither fossil fuels nor burning wood contributes to an increase in atmospheric concentrations of carbon dioxide.

Explanation:

Fossil fuel combustion releases carbon - dioxide into the atmosphere, increasing its concentration. Forest fires also release carbon - dioxide stored in trees. Neither process absorbs carbon - dioxide from the air.

Answer:

The combustion of fossil fuels and burning wood contribute to an increase in atmospheric concentrations of carbon dioxide.
