Solution
Mechanism of Greenhouse effect
- Sunlight reaching the earth consists of various types of radiation: ultraviolet (UV) radiation, visible radiation, infra-red (IR) radiation.
- When sunlight enters the atmosphere, the maximum amount of UV radiation is absorbed by ozone.
- 30% of IR radiation reaches the earth's surface, heating up the surface.
- As the earth gets warmer, it starts emitting radiation with less energy than incoming radiation and therefore with a longer wavelength.
- Some emitted infrared radiations escape from the earth's surface as well as by CO2, thus remaining on the earth.
