| (i) How is the greenhouse effect produced? |
| (ii) Explain the major harm caused by greenhouse gases. |
Answer:
(i) The glasswalls, high \[C{{O}_{2}}\] content and high water vapour content inside the greenhouse let the short-wave solar radiation enter but impede the exit of long-wave radiation emitted by the earth's surface. This makes the greenhouse air warmer than outside air. (ii) Greenhouse gases are mainly responsible for the enhanced greenhouse effect and global warming. CFCs particularly are responsible for depletion of ozone layer and formation of ozone hole.
