Which one of the following pairs of gases are the major cause of 'Greenhouse effect?

Options

A. `CO_(2)` and `CO`
B. CFCs and `SO_(2)`
C. `CO_(2)` and `N_(2)O`
D. `CO_(2)` and `O_(3)`

Answer

C

Explanation

The phenomenon of keeping the earth's surface warm is due to the presence of certain gases in the atmosphere that are called greenhouse gases. The name is based after a similar warmer interior in a glass-enclosed greenhouse where glass panels, `CO_(2)` and water vapour allow the solar radiations to enter but prevent the escape of long wave heat radiations. `CO_(2)` and `N_(2)O` are the major cause of 'greenhouse effect'. `CO_(2)` contributes 60% of total global warming. `N_(2)O` contributes 6% to greenhouse effect.
