FAQs on Worksheet: Green House Effect - General Knowledge Encyclopedia - Class 8
| 1. What is the greenhouse effect and how does it work? |  |
Ans. The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth, some of it is reflected back to space and the rest is absorbed, warming the planet. The Earth's surface then emits this energy in the form of infrared radiation. Greenhouse gases in the atmosphere, such as carbon dioxide, methane, and water vapor, trap some of this infrared radiation, preventing it from escaping into space. This trapped energy warms the atmosphere and the surface of the Earth, leading to a rise in temperature.
| 2. What are the main greenhouse gases contributing to the greenhouse effect? | |
Ans. The main greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor (H2O). Carbon dioxide is primarily produced by burning fossil fuels, deforestation, and various industrial processes. Methane is released during the production and transport of coal, oil, and natural gas, as well as from livestock and other agricultural practices. Nitrous oxide is emitted from agricultural and industrial activities, as well as during combustion of fossil fuels and solid waste.
| 3. How does human activity contribute to the greenhouse effect? | |
Ans. Human activities significantly contribute to the greenhouse effect primarily through the burning of fossil fuels for energy, deforestation, and industrial processes. These actions increase the concentration of greenhouse gases in the atmosphere. For example, burning coal, oil, and natural gas releases large amounts of carbon dioxide, while agricultural practices and livestock farming release methane and nitrous oxide. This enhanced greenhouse effect leads to global warming and climate change.
| 4. What are the potential impacts of the greenhouse effect on the environment? | |
Ans. The greenhouse effect can lead to several environmental impacts, including global warming, rising sea levels, and changes in weather patterns. As temperatures rise, polar ice melts, contributing to sea-level rise and increasing the risk of flooding in coastal areas. Additionally, extreme weather events, such as hurricanes and droughts, are likely to become more frequent and severe. These changes can disrupt ecosystems, harm wildlife, and affect agriculture and water supply.
| 5. What steps can be taken to mitigate the greenhouse effect? | |
Ans. To mitigate the greenhouse effect, several steps can be taken, including reducing fossil fuel consumption by transitioning to renewable energy sources like solar and wind, improving energy efficiency, and promoting sustainable transportation options such as public transit and electric vehicles. Additionally, reforestation and afforestation efforts can help absorb carbon dioxide from the atmosphere. Raising awareness and implementing policies aimed at reducing greenhouse gas emissions are also crucial in combating climate change.
