The atmosphere's variable gases that most influence the greenhouse effect are nitrogen and oxygen argon and carbon dioxide carbon dioxide and water vapor water vapor and ozone

The correct answer is carbon dioxide and water vapor

These negative gasses get modified and then remain in the atmosphere without the possibility of leaving, which is why the greenhouse effect occurs.

Answer;

Carbon dioxide and water

The atmosphere's variable gases that most influence the greenhouse effect are carbon dioxide and water.

Explanation;Green house effect is a phenomenon where the radiation from the atmosphere of the earth warms the surface of the earth to a temperature above what it would be. It occurs when the atmosphere traps heat radiating from the earth towards the space.Certain gases in the atmosphere block the heat from escaping, these gases are called the green house gases. These gases contribute to the green house effect, they include, water vapor which is the most abundant green house gas, carbon dioxide a very important component of the atmosphere, methane, nitrous oxide, CFCs, etc.
