A) Pasteur effect
B) Green-house effect
C) Blackman effect
D) Emerson effect
Correct Answer: B
Solution :
In the earths atmosphere, if there is an increase in \[C{{O}_{2}}\] concentration, then the thick layer of this gas prevents the heat from being re-radiated out. This thick \[C{{O}_{2}}\]layer thus functions like the glass pannels of a green-house allowing the sunlight to filter through but preventing the heat from being re-radiated in outer space. This is called green-house effect or global warming or carbon dioxide problem. The other gases responsible for green-house effect are \[C{{H}_{4}},\text{ }CFCs\]and \[{{N}_{2}}O.\]
