Question

Increase in atmospheric temperature due to $C{O}_2$ is

• A. Pasteur effect
• B. Blackman effect
• C. Emerson effect
• D. Green-house effect

Answer 1

The correct option is D Green-house effect

A. Pasteur effect is the inhibition of fermentation or oxidation of glucose when the concentration of oxygen is increased.

B. Blackman effect describes the law of limiting factors according to which if a process is dependent on a number of factors then its rate is limited by the slowest factor.

C. Emerson effect is the increase in rate of photosynthesis when the light intensity is increased beyond 680 nm.

D. Green house effect is the increase in atmospheric temperature due to warming of earth's surface when the sun radiations are trapped in the earth. The radiations are trapped in earth because of green house gases like carbon dioxide.
