Weekly Quiz Competition

Question 1
1 / -0

Ozone layer depletion is caused by

A
AFC's

B
BFC's

C
CFC's

D
DFC's

Solution
Question 2
1 / -0

Kyoto protocol is a multination international treaty for

A
phasing out greenhouse gases

B
controlling ozone destroying substances

C
management of hazardous wastes

D
conservation of biodiversity

Solution

The Kyoto protocol is an international treaty which extends the 1992 united nations framework convention on climate change (UNFCC) that commits state parties to reduce greenhouse gas emissions, based on the scientific consensus that global warming is occurring.
So, the correct option is Phasing out greenhouse gases.
Question 3
1 / -0

When there is depletion of ozone in the stratosphere the wavelength of radiation striking the earth's surface will be ............

A
$$10^{-2}$$ m

B
$$10^{-7}$$ m

C
$$10^{-10}$$ m

D
100 m
Question 4
1 / -0

Consider the following statements (A-D) about organic farming
(a) utilizes genetically modified crops like Bt cotton
(b) uses only naturally produced inputs like compost
(c) does not use pesticides and urea
(d) produces vegetables rich in vitamins and minerals.
Which of the given statements are correct?

A
B, C and D

B
C and D only

C
B and C only

D
A and B only

Solution

Organic farming uses only naturally produced inputs like compost and organic farming doesn't use pesticides and urea.
So, the correct option is 'B and C only'
Question 5
1 / -0

Which of the following are main responsible for ozone depletion?

A
Chlorofluorocarbons

B
Hydrocarbons

C
Carbon monoxide

D
Carbon dioxide
Solution
- Ozone depletion occurs when chlorofluorocarbons (CFCs) present in aerosols and refrigerants are released into the stratosphere.
- Ultraviolet radiations from the sun break these CFCs molecules and release the chlorine atoms.
- Chlorine atom reacts with the ozone (O₃) molecules and starts the ozone destruction cycle.
- So, the correct answer is 'Chlorofluorocarbons'.
Question 6
1 / -0

Which of the following methods of waste management produce energy?

A
Biomedical waste management

B
Safe landfill sites

C
Industrial solid waste management

D
Pyrolysis
Question 7
1 / -0

Snow blindness is caused due to

A
Global warming

B
Ozone depletion

C
Greenhouse effect

D
Bio magnification

Solution

Snow blindness also called as photokeratitis occurs due to reflection of UV light from the surface of the snow, where the layer of ozone is thin and allows maximum penetration of UV light on the surface of the earth. This condition is majorly observed at the poles.
So, the correct answer is 'ozone depletion'
Question 8

Which device is/are used to control $$3-4$$ benzopyrine and benzene from automobile exhaust?
(a) Electrostatic precipitation
(b) Multi point injection engine
(c) Dry scrubber
(d) Catalytic conventer

A
Only a

B
a & b

C
b & d

D
donly

Solution
Question 9
1 / -0

A
Any pesticide they choose

B
Only pesticides are derived from natural sources such as microbes, insects, minerals.

C
No pesticides at all

D
