Sl.No. | Global warming | Acid rain |
1. | The rise in the temperature on the surface of the earth is called global warming. It might be due to phenomena like green house effect. | The reaction of air pollutants such as oxides of sulphur and nitrogen with water vapour and oxygen of the earth’s atmosphere results in the formation of dilute sulphuric and nitric acids. When these acids mix with rain water, they pour down as Acid rain. |
2. | Carbon dioxide and methane are the gases mainly responsible for global warming. | Oxides of sulphur and nitrogen contribute to the formation of acid rain on earth. |
