Question 1
1 / -0

Which one of these gases is not a greenhouse gas?

A
$$CO_2$$

B
$$CH_4$$

C
$$H_2O$$

D
$$NO_2$$

Solution

The primary greenhouse gases in Earth's atmosphere are water vapour ($$H_2O$$), carbon dioxide ($$CO_2$$), methane ($$CH_4$$) and ozone ($$O_3$$).
Hence, option $$D$$ is not a greenhouse gas.
Question 2
1 / -0

Which of them can help in controlling water pollution?

A
Use the minimum amount of detergent and/or bleach when you are washing clothes or dishes

B
Minimize the use of pesticides, herbicides, fertilizers. Do not dispose of chemicals, motor oil, or other automotive fluids into the sanitary sewer or storm sewer systems

C
Avoid using the toilet as a wastebasket

D
All of the above

Solution

Minimize the use of pesticides, herbicides, fertilizers. Do not dispose of chemicals, motor oil, or other automotive fluids into the sanitary sewer or storm sewer systems. Both of them end at the river.
Avoid using the toilet as a wastebasket. Most tissues, wrappers, dust cloths, and other paper goods should be properly discarded in a wastebasket. The fiber reinforced cleaning products that have become popular should never be discarded in the toilet.
Use the minimum amount of detergent and/or bleach when you are washing clothes or dishes. Use only phosphate-free soaps and detergents.
Question 3
1 / -0

What can we do to save water?

A
Reduce, reuse, recycle

B
Cooling

C
Filtration

D
None of above

Solution

To save water, we should reduce its use, reuse water where possible and recycle it so that we don't fall into water shortage.
Question 4
1 / -0

Greenhouse gases are those that can absorb and emit infrared radiation. Which of the following is not a greenhouse gas?

A
Water vapour

B
Carbon Dioxide

C
Methane

D
Hydrogen

Solution

A greenhouse gas is a gas which adsorbs infrared radiation in thermal range and causes global warming. The primary greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone.
Question 5
1 / -0

The greenhouse gas is:

A
$$CO_2$$

B
$$SO_2$$

C
$$N_2$$

D
$$ H_2 S $$

Solution

Carbon dioxide, $$CO_2$$ allows the passage of short wave radiations such as ultraviolet and visible radiations but impedes the passage of infrared (or heat) radiations.
Consequently, the temperature of the earth's surface gets increased. This is known as the greenhouse effect. Hence, $$CO_2$$ is the major greenhouse gas.
Other greenhouse gases are $$ CH_4 , N_2 O $$ and $$ H_2O $$ etc.
Question 6
1 / -0

In which of the following pairs, both of them are common greenhouse gases?

A
Oxygen, water vapour

B
Methane, carbondioxide

C
Ozone, nitrogen

D
Methane, Oxygen

Solution

The primary greenhouse gases are water vapour, carbon dioxide, methane, nitrous oxide and ozone.
Question 7
1 / -0

Most abundant water pollutant is

A
Detergents

B
Industrial wastes

C
Pesticides

D
Oil spills

Solution

Detergents, oil spills, pesticides, industrial waste, all these are water pollutants but industrial waste is the most abundant water pollutants.
Question 8
1 / -0

Which of the following are greenhouse gases?

A
Carbon dioxide, methane, nitrous oxide, water vapour

B
Carbon dioxide, chlorine, nitrogen

C
Methane, oxygen, helium, neon

D
None of these

Solution

Carbon dioxide, methane, nitrous oxide and water vapour are greenhouse gases present in earth's atmosphere. They trap sun's heat and result in increasing of earth's temperature.
Question 9
1 / -0

Oil refineries, paper factories, textile and sugar mills, chemical factories are responsible for water pollution. These industries discharge harmful chemicals into rivers and streams and pollute water. The chemicals released include ________.

A
arsenic

B
lead

C
fluorides

D
all of the above

Solution

Oil refineries, paper factories, textile and sugar mills, chemical factories are responsible for water pollution.These industries discharge harmful chemicals into revers and streams, and pollute water. The chemicals released include arsenic, lead and fluorides which lead to toxicity in plants and animals.
Question 10
1 / -0

Which of the following initiative was launched for cleaning the Ganga river?

A
National Mission for Clean Ganga

B
National Mission for Clean Gange

C
National Mission for Cleaning Ganga

D
None of the above

Solution

In 1985, the Ganga Action Plan was launched to reduce the pollution levels in rivers.
But the increasing population and industrialization has already damaged this mighty river beyond repair.
Now, The Government of India has launched a new initiative known as National Mission for Clean Ganga (NMCG) in 2016.
So, the correct answer is 'National Mission for Clean Ganga'.
