Q. Explain briefly how the greenhouse effect occurs.

Q. Trapping of environmental heat by the gases present in atmosphere like carbon dioxide, methane, ozone and dust is known as:

1. Lightning effect
2. Greenhouse effect
3. Radioactive effect
4. Solar effect

Q.

When did global warming get worse?

Q. Global warming is the result of
