The oceans help provide an exchange of gases with the atmosphere by dissolving

a) oxygen
b) carbon dioxide
c) volcanic ash
d) all the above
e) a and b only

e

e is correct. Ash cannot be dissolved.

thanks mr bobpursely :)

To confirm the correct answer, we can break down each choice and understand how the oceans contribute to the exchange of gases with the atmosphere.

a) Oxygen: The oceans play a crucial role in absorbing and storing oxygen from the atmosphere. Through processes like diffusion, oxygen molecules move from the air into the surface waters of the ocean, allowing for the transfer of oxygen between the atmosphere and the ocean.

b) Carbon Dioxide: The oceans also help regulate the amount of carbon dioxide (CO2) in the atmosphere. They act as a carbon sink, absorbing a significant portion of the CO2 produced by human activities and natural processes. This process, known as carbon sequestration, helps mitigate the impacts of greenhouse gas emissions and climate change.

c) Volcanic Ash: While the oceans can be impacted by eruptions and volcanic activity, the dissolution of volcanic ash in seawater does not significantly contribute to the exchange of gases with the atmosphere. Therefore, volcanic ash is not relevant to this particular question.

Based on the explanations above, the correct answer is e) a and b only, as the oceans help provide an exchange of gases with the atmosphere by dissolving oxygen and carbon dioxide.
