Greenhouse Gases: Impact & Sources Homework Answers

Your question:

What is Green House gas?

Why is the name Green House Gas?

Assignment Help Answers with Step-by-Step Explanation:


Greenhouse gases (GHGs) are a class of naturally occurring and man-made compounds that play a critical role in shaping the Earth's climate. These gases are named "greenhouse" because, like the glass of a greenhouse, they allow sunlight to enter the atmosphere but trap heat, leading to a warming effect. This natural phenomenon is essential for maintaining the Earth's temperature at a level suitable for life. However, the excessive accumulation of these gases due to human activities has led to the enhanced greenhouse effect, resulting in global warming and climate change. In this essay, we will explore three of the most important greenhouse gases, their sources, and the environmental consequences of their increased concentration in the atmosphere.

Methane is another significant greenhouse gas, although it is less abundant than carbon dioxide. It is produced by natural sources like wetlands, termites, and the digestive processes of animals. Human activities, particularly the production and transport of natural gas, livestock farming, and the decay of organic waste in landfills, have led to a substantial increase in atmospheric methane concentrations. Despite being less prevalent, methane is approximately 25 times more potent as a heat-trapping gas than carbon dioxide over a 100-year period.

3. Nitrous Oxide (N2O):

  • Deforestation: The removal of forests reduces the planet's capacity to absorb CO2.

  • Industrial Processes: Cement production, steel manufacturing, and other industrial activities release CO2 emissions.

3. Nitrous Oxide:

  • Agriculture: The use of synthetic fertilizers in agriculture is a major source of nitrous oxide.

  1. Climate Change: Rising temperatures lead to more frequent and severe weather events, such as hurricanes, droughts, and heatwaves.

  2. Melting Ice Caps: The warming climate results in the melting of glaciers and ice caps, contributing to rising sea levels.
