Question

Which of the following air pollutants are responsible for the greenhouse effect? 1. Methane 2. Carbon Dioxide 3. Chlorofluorocarbons 4. Nitrogen Oxides​

Answer 1

Answer:

These gases, collectively called greenhouse gases, include carbon dioxide, organic chemicals called chlorofluorocarbons (CFCs), methane, nitrous oxide, ozone, and many others.

Global warming is caused primarily due to emission of carbon dioxide. Other pollutants contributing to global warming includes methane, nitrous oxide and CFCs.

Answer 2

• All the ( methane, carbon dioxide, chlorofluorocarbon,nitrogen oxide) air pollutants are responsible for the greenhouse effects.
• All these gases, collectively called greenhouses gases, includes carbon dioxide,organic chemicals called chlorofluorocarbons, methane, nitrous oxide.
• Earth's greenhouse gases trap heat in the atmosphere and warm the planet.
• When the sun's energy reaches the earth's atmosphere, some of it is reflected back to the space and some absorbed and re-radiated by greenhouse gases.
• The absorbed energy warms the atmosphere and surface of the earth.
• The green house effects: some of the infrared radiation from the sun passes through the atmosphere, but absorbed and re-emitted in all directions by greenhouse gas molecules and clouds.
• The gases that contribute most to the earth's greenhouse effects are:

                            Water vapour(H2O)

                             Carbon dioxide(CO2)

                             Nitrous oxide(N2O)

                              Methane(CH4)

                              Ozone(O3)

• For example, CO2 in the atmosphere and the amount of CO2 dissolved in surface water of the ocean stay in equilibrium.
• When add more CO2 to the atmosphere, a proportion of it dissolved in the oceans.
