Which gasses in the atmosphere contribute to the greenhouse effect?a.Carbon monoxide and sulfur dioxideb.Oxygen and nitrogenc.Hydrogen and heliumd.Methane and nitrous oxide

The gases in the atmosphere that contribute to the greenhouse effect are methane and nitrous oxide. Therefore, the correct answer is d. Methane and nitrous oxide.

Here's a step-by-step explanation:

1. The greenhouse effect is a natural process that warms the Earth’s surface. It is caused by certain gases in the atmosphere that trap heat from the sun.

2. These gases are called greenhouse gases and they include carbon dioxide, methane, nitrous oxide, and water vapor.

3. While carbon monoxide and sulfur dioxide (option a) can contribute to air pollution, they are not considered major greenhouse gases.

4. Oxygen and nitrogen (option b) make up a large portion of the Earth's atmosphere, but they do not contribute significantly to the greenhouse effect.

5. Hydrogen and helium (option c) are also not considered major greenhouse gases.

6. Methane and nitrous oxide (option d) are both potent greenhouse gases. Methane is released during the production and transport of coal, oil, and natural gas.
