The gases that produce green house effect are
Options
- ACH ₄, (CFCs) , CO ₂
- BCO ₂, ~N ₂ O , H ₂
- CCFCs , NO ₂, O ₂
- DCO ₂, ~N ₂ , water vapour
Correct answer
A. CH ₄, (CFCs) , CO ₂
Step-by-step solution
Green house effect is the CO ₂ effect. It is due to CO ₂ layer in atmosphere and also by (CFCs) , SO ₂, NO ₂, CH ₄ . These gases come from factories, automobile, agriculture, refrigerators, deforestation. These gases entrap the solar heat and prevents the escape of heat from earth to outer space, thus increasing the temperature of earth which further lead to global warming.
