FAQs on Causes of Global Warming Video Lecture - Class 8

1. What are the main causes of global warming?
Ans. The main causes of global warming are the increased concentration of greenhouse gases in the Earth's atmosphere. This is primarily due to human activities such as burning fossil fuels, deforestation, and industrial processes.
2. How does burning fossil fuels contribute to global warming?
Ans. Burning fossil fuels releases carbon dioxide (CO2) and other greenhouse gases into the atmosphere. These gases trap heat from the sun and cause the Earth's temperature to rise, leading to global warming.
3. How does deforestation contribute to global warming?
Ans. Deforestation involves the cutting down of trees, which are vital for absorbing carbon dioxide through the process of photosynthesis. When forests are destroyed, the stored carbon is released back into the atmosphere as carbon dioxide, contributing to global warming.
4. What role do industrial processes play in global warming?
Ans. Industrial processes, such as manufacturing, mining, and construction, produce greenhouse gases as byproducts. These gases, including carbon dioxide, methane, and nitrous oxide, contribute to the greenhouse effect and subsequently lead to global warming.
5. How do greenhouse gases contribute to global warming?
Ans. Greenhouse gases, such as carbon dioxide, methane, and nitrous oxide, act as a blanket in the Earth's atmosphere. They trap heat from the sun and prevent it from escaping back into space, causing the Earth's temperature to rise and resulting in global warming.
