A naturally occuring phenomenon that is responsible for heating of earth's surface and atmosphere due to the presence of certain gases in the atmosphere is
1 Radioactive pollution
2 Greenhouse effect
3 Ozone layer effect
4 Thermal pollution
Explanation:
The greenhouse effect is a naturally occurring phenomenon that is responsible for heating of Earth's surface and atmosphere. Without greenhouse effect the average temperature at surface of Earth would have been a chilly \(-18^{\circ} \mathrm{C}\) rather than the present average of \(15^{\circ} \mathrm{C}\).
