Question 1
1 / -0

Which of the following is not a greenhouse gas?

A
$$CO_{2}$$

B
$$N_{2}O$$

C
$$CH_{4}$$

D
$$O_{2}$$

Solution

Greenhouse gases are those which tend to trap the heat coming from the sun by absorbing the infrared radiation and don't allow it to escape called the greenhouse effect, ultimately leading to an increase in the global temperature. Except for oxygen, all other given gases have the potential to create the greenhouse effect.
Question 2
1 / -0

Which of the following pollutants is not harmful to the lungs?

A
$$CO$$

B
$$SO_2$$

C
$$CO_2$$

D
$$NO_2$$

Solution

$$A)$$ The respiratory system struggles to distribute air around the body because carbon monoxide deprives the blood cells of oxygen. This results in shortness of breath, particularly when undertaking strenuous activities. As a result, the airways begin to swell causing even less air to enter the lungs.

$$B)$$ High concentrations of $$SO_2$$ can affect lung function, worsen asthma attacks, and worsen existing heart disease in sensitive groups. This gas can also react with other chemicals in the air and change to a small particle that can get into the lungs and cause similar health effects.

$$C)$$ $$CO_2$$ is not poisonous; as a gas, $$CO_2$$ itself will not hurt you. This is an important fact to remember, as carbon dioxide is a vital part of the environment. The human breathing mechanism actual revolves around $$CO_2$$, not oxygen. Without carbon dioxide, humans wouldn't be able to breathe.

$$D)$$ When nitrogen dioxide is inhaled at high enough levels, it reacts with and damages lung cells, including those cells that fight infection. This damage can affect breathing and may increase the risk of respiratory infections.

$$\mathbf{Hence\ the\ correct\ answer\ is\ option\ (C)}$$
Question 3
1 / -0

Which of the following is not a greenhouse gas?

A
Nitrogen gas

B
Water vapour

C
Methane gas

D
Carbon dioxide

Solution

Earth's greenhouse gases trap heat in the atmosphere and warm the planet. Greenhouse gases are carbon dioxide, water vapour, methane, nitrous oxide Nitrogen gas is not a greenhouse gas as it does not trap heat and does not contribute to global warming.
Hence, Option $$A$$ is the correct answer.
Question 4
1 / -0

Low visibility during cold weather can be due to:

A
fog

B
smoke from industries and vehicles

C
both A and B

D
none of A or B

Solution

During cold weather, water droplets instead of moving up at a higher altitude stay near the earth's surface and cause fog. Along with this, a lot of vehicular emissions and smoke from industries contain oxides of nitrogen which combine with other air pollutants and fog to form smog.

The smog causes breathing difficulties such as asthma, cough and wheezing in children. Also as they both remain suspended in the air causing the visibility to reduce during cold weather.
Question 5
1 / -0

The type of pollution which is likely to affect Taj Mahal in Agra to a greater extent is

A
Air pollution

B
Soil pollution

C
Water pollution

D
Noise pollution

Solution

Air pollution is harming the Taj Mahal in such a way that the white marble of the monument corroding and yellowing marble.
Hence, Option "A" is the correct answer.
Question 6
1 / -0

Choose the correct alternative from the choice given for the following statements:
Air consists of:

A
oxygen

B
nitrogen

C
carbon dioxide

D
All of these

Solution

Answer is Option D.
Air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon and hydrogen.
Question 7
1 / -0

The holy river of India is:

A
Ganga

B
Bedach

C
Banas

D
Kosi

Solution

The holy river of India is Ganga. The whole river from Himalayan glaciers across the vast north Indian plain to the filigree delta on the Bay of Bengal is worshipped as a life-affirming goddess.
Question 8
1 / -0

The component which is not present in air is?

A
Nitrogen

B
Oxygen

C
Carbon dioxide

D
Chlorine

Solution

Air does not contain chlorine. It is a mixture of other gases like nitrogen, oxygen, carbon dioxide, helium, hydrogen, argon, etc.
Question 9
1 / -0

In which year Ganga Action Plan was launched ?

A
$$1980$$

B
$$1984$$

C
$$1982$$

D
$$1985$$

Solution

An ambitious plan to save the river, called the $$\text {Ganga Action Plan}$$ was launched in $$1985$$.
Question 10
1 / -0

Which is the most abundant gas in the atmosphere?

A
$$ Oxygen $$

B
$$ Nitrogen $$

C
$$ Carbon dioxide $$

D
$$ Other \ gases $$

Solution

The air in Earth's atmosphere is made up of approximately $$78$$% nitrogen and $$21$$% oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen
Hence answer is $$ Nitrogen $$
