Q. Which of the following is true with regards to the greenhouse effect?

1. The average temperature of the earth noticeably rises due to the greenhouse effect.
2. Incoming UV radiation enters a greenhouse and is absorbed by plants and surfaces inside.
3. The greenhouse effect happens only with plants grown in “glasshouses” in relatively cold regions.
4. The greenhouse effect causes global climate change.

Q. Process of re-radiating heat by atmospheric dust water vapour, ozone, $C{O}_2$, etc. is known as:

1. Greenhouse effect

Q.

Identify the correctly matched pair among the following.

1. Basel convention ---- Biodiversity conservation

Q. Which among the following are Greenhouse Gases (GHGs)?

1. Carbon dioxide
2. Methane
3. Nitrogen
4. Chlorofluorocarbons

Q. Regarding the assertion and reason, choose the correct option.
Assertion [A]: Greenhouse effect is due to a thick layer of CO₂.
Reason [R]: The glass panels of a greenhouse allow the sunlight to filter through but prevent heat from being re-radiated into outer space.

1. Both A and R are true and R is the correct explanation of A
