Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Combustion of fossil fuels increases which gas in the atmosphere?
A
oxygen
B
carbon dioxide
C
nitrogen
D
carbon monoxide
Explanation: 

Detailed explanation-1: -When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming.

Detailed explanation-2: -During combustion, the carbon (C) from the fuel combines with oxygen (O2) from the air to produce carbon dioxide (CO2). The additional weight comes from the oxygen.

Detailed explanation-3: -Over the last century, burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This increase happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.

Detailed explanation-4: -The burning of fossil fuel produces acidic oxides of Carbon, Nitrogen & Sulphur which causes acid rains which affect our water and soil resources.

Detailed explanation-5: -Human activities that lead to carbon dioxide emissions come primarily from energy production, including burning coal, oil, or natural gas.
