Oceans regulate Earth’s climate because they remove CO2 and release O2.

Answer 1

"Oceans regulate Earth’s climate because they remove CO2 and release O2."

Reason: Aquatic plants and phytoplankton photosynthesize, taking up CO2 from the water/atmosphere and producing oxygen, and the oceans act as a major carbon sink that helps regulate climate.
