Final answer:
The major greenhouse gases in the atmosphere are water vapor, carbon dioxide, 4)methane, and nitrogen oxide; the correct choice is methane, carbon dioxide, and water vapor.
Step-by-step explanation:
The major greenhouse gases in the atmosphere are water vapor, carbon dioxide, methane, and nitrogen oxide. Therefore, the correct choice from the given options would be 4) Methane, carbon dioxide, and water vapor.
Additional gases such as nitrous oxide, ozone, and chlorofluorocarbons (CFCs) also contribute to the greenhouse effect. The primary human activities.
Increasing the concentrations of these gases include burning fossil fuels, deforestation, and the use of certain industrial chemicals.
