Question

Which of the following is the correct cause for human induced green house effect?

• A. Use of chemical fertilizers
• B. Burning of fossil fuels
• C. Both (a) and (b)
• D. Afforestation

Answer 1

The correct option is C Both (a) and (b)

Just as the glass in a greenhouse holds the sun’s warmth inside, the atmosphere traps the sun’s heat near the earth’s surface and
keeps it warm. This is called the natural greenhouse effect.

If the amount of $C{O}_2$ in air increases, natural green house balance is disturbed and the atmosphere gets heated. This causes global warming.

Use of chemical fertilizers and burning of fossil fuels increases the greenhouse effect. This is known as human induced green house effect. Hence the correct answer is option (c).
