methane

carbon dioxide

nitrogen

argon

- Correct Answer: Option 2 - Carbon Dioxide

- Ocean acidification is the process of decreasing pH levels in oceans.

- It's primarily caused by the absorption of carbon dioxide (CO2) from the atmosphere.

- CO2 reacts with seawater, forming carbonic acid, which lowers ocean pH.

- Methane (Option 1) affects climate change but doesn't directly affect ocean acidification.

- Nitrogen (Option 3) is crucial for marine life but isn’t directly responsible for acidification.

- Argon (Option 4) is an inert gas and does not contribute to ocean chemistry changes.
