Question

5. What are the sources of greenhouse effect gases? How can their excessive production be
checked?​

Answer 1

Explanation:

 greenhouse gas (sometimes abbreviated GHG) is a gas that absorbs and emits radiant energy within the thermal infrared range. Greenhouse gases cause the greenhouse effect[1] on planets. The primary greenhouse gases in Earth's atmosphere are water vapor (H

2O), carbon dioxide (CO

2), methane (CH

4), nitrous oxide (N

2O), and ozone (O3). Without greenhouse gases, the average temperature of Earth's surface would be about −18 °C (0 °F),[2 rather than the present average of 15 °C (59 °F).[The atmospheres of Venus, Mars and Titan also contain greenhouse gases.

Answer 2

Explanation:

Some greenhouse gases, such as methane, are produced through agricultural practices, in the form of livestock manure, for example. Others, like CO2, largely result from natural processes like respiration, and from the burning of fossil fuels like coal, oil and gas. Another primary source of CO2 is deforestation.
