Greenhouse Gases and Atmosphere

Methane is the primary component of natural gas, typically constituting 70-90% of its composition. Natural gas is formed from the decomposition of organic matter under high pressure and temperature conditions deep underground. While natural gas contains small amounts of ethane, propane, butane, and other hydrocarbons, methane remains the dominant and most significant component by volume.

Butane gas is the main constituent of cooking gas.

Methane (CH4) is the primary component of both biogas (50-75%) and natural gas (70-90%). Biogas is produced through anaerobic decomposition of organic matter, while natural gas is a fossil fuel extracted from underground reserves.

Sulphur trioxide (SO3) is not a greenhouse gas. It rapidly forms sulfate aerosols in the atmosphere which actually scatter solar radiation and contribute to cooling, not warming. Methane, nitrous oxide, and carbon dioxide are all well-established greenhouse gases with significant radiative forcing effects.

This is the correct option as nitrogen is not a greenhouse gas.

Carbon monoxide is considered to be a non-greenhouse gas. Though CO absorbs infrared rays, it is highly unstable and does not significantly contribute to greenhouse effect. 

Global warming is primarily caused by the increased concentration of greenhouse gases, with Carbon Dioxide (CO2) being the most significant contributor due to human activities like burning fossil fuels.

Carbon dioxide (CO2) is the primary greenhouse gas responsible for trapping heat in the atmosphere, leading to the greenhouse effect. Other gases listed, like Helium, do not contribute to this effect in the same way.

Carbon dioxide is the primary greenhouse gas emitted through human activities, such as burning fossil fuels. While water vapor is a greenhouse gas, carbon dioxide is the most significant contributor to the enhanced greenhouse effect.

Hydrogen gas is highly flammable and burns in air. So it is not a greenhouse gas.

This is the correct option. Carbon dioxide is the gas that causes global warming.

Greenhouse gases trap heat in the atmosphere. Carbon dioxide, nitrous oxide, and chlorofluorocarbons (CFCs) are well-known contributors to the greenhouse effect.
