Solution
Greenhouse effect:
- Solar energy is absorbed by the surface of the seas and terrestrial plants. This absorbed radiation is converted into heat and re-radiated back into space.
- Infrared radiation (IR) is absorbed by certain gaseous molecules in the environment and re-radiated in all directions. As a result, these gases keep the earth's surface temperature stable.
- The gases that absorb these IR rays are known as greenhouse gases, and the process is known as the greenhouse effect.
- CO2, H2O, N2O, CH4, O3, and CFCs are examples of greenhouse gases.
