<u>Answer:</u>
Greenhouse gas refers to any gaseous compound in the atmosphere that can absorb infrared radiation, thereby trapping heat and keeping it in the atmosphere. By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming.
<u>Examples why greenhouse gases in the atmosphere:</u>
- farming cattle releases methane
- farming rice in paddy fields releases methane
- burning fossil fuels in vehicles and power stations releases carbon dioxide
- deforestation releases carbon dioxide and reduces the absorption of carbon dioxide through photosynthesis
