The correct answer is: C. Carbon dioxide.
Carbon dioxide is the main greenhouse gas in Earth’s atmosphere. It is produced by the burning of fossil fuels, such as coal, oil, and natural gas. It is also released from the burning of wood and other biomass, as well as from the decay of organic matter.
Carbon dioxide is
a greenhouse gas because it traps heat in the atmosphere. When sunlight hits the Earth’s surface, some of the energy is reflected back into space. However, some of the energy is absorbed by the Earth’s surface and converted into heat. This heat then radiates back into the atmosphere, where it is absorbed by greenhouse gases, such as carbon dioxide. This process traps heat in the atmosphere, which causes the Earth’s temperature to rise.The other options are incorrect because they are not greenhouse gases. Ozone is a gas that is found in the stratosphere, which is the layer of the atmosphere that is above
the troposphere. Oxygen is a gas that is found in the troposphere, and it is essential for life on Earth. Carbon monoxide is a gas that is produced by the incomplete combustion of fossil fuels. It is a poisonous gas that can cause death if inhaled in high concentrations.In conclusion, the gas which is mainly responsible for the greenhouse effect is carbon dioxide.
