Question

question: approximately 25 percent of the ___ emitted into the atmosphere is absorbed in oceans.
answer options:
select one of four
oxygen
chlorofluorocarbons
methane
carbon dioxide

Explanation:

Oceans play a significant role in absorbing carbon dioxide (\(CO_2\)) from the atmosphere. Oxygen is produced by oceans (via photosynthesis of marine plants) and is not mainly absorbed by oceans in this context. Chlorofluorocarbons are synthetic compounds that deplete the ozone layer and are not significantly absorbed by oceans. Methane is also not absorbed by oceans to the extent of carbon dioxide in this percentage - related context. So the gas that is approximately 25 percent absorbed by oceans from the atmosphere is carbon dioxide.

Answer:

carbon dioxide
