Q: Which of the following gases is primarily responsible for the greenhouse effect and global warming?

a) Carbon monoxide (CO)
b) Methane (CH4)
c) Nitrous oxide (N2O)
d) Oxygen (O2)

Answer: b) Methane (CH4)

Brief Fact: Methane is a potent greenhouse gas that contributes significantly to global warming. It is released through various human activities such as agriculture (livestock and rice cultivation), fossil fuel extraction and combustion, and waste management (landfills). Methane has a much higher warming potential compared to carbon dioxide (CO2) over a specific time frame. Its accumulation in the atmosphere traps heat and contributes to the greenhouse effect, leading to the warming of the Earth's surface and climate change. Efforts to reduce methane emissions are crucial in mitigating global warming and its impacts on the environment.

Dark Net, Deep Web and Surface Web

✅"Dark net" is commonly confused with "deep web." The deep web refers to unindexed sites which are unsearchable; in most cases, this is because those sites are protected by passwords.

✅Part of the WWW (World Wide Web) which is not indexed by a search engine like Google is Deep Web and it about 500-600 times larger than the surface web.

✅Surface Web -Also called the Visible Web, Indexed Web, Indexable Web or Lightnet -is that portion of the World Wide Web that is readily available to the general public and searchable with standard web search engines. It is the opposite of the deep web. It only constitutes 4-6% of the whole web. @civilservicesBaba
