This set of Energy & Environment Management Multiple Choice Questions & Answers (MCQs) focuses on “Acid Rain”.
1. Which one of the following cause acid rain?
a) Water pollution
b) Soil pollution
c) Air pollution
d) Noise Pollution
View Answer
Explanation: Acid rain is mainly caused due to a result of air pollution. When any type of fuel is burnt, lots of different chemicals are produced. Some of the gases react with tiny droplets of water. This rain from clouds forms acid rain.
2. What are two acids formed when gases react with the tiny droplets of water in clouds?
a) Sulphuric acids and nitric acid
b) Hydrochloric acid and nitric acid
c) Sulfurous acid and acetylsalicylic acid
d) Sulphuric acid and hydrochloric acid
View Answer
Explanation: The gases of nitrogen oxides and sulphur dioxide react with the tiny droplets of water in clouds to form sulphuric and nitric acid. The rain from these clouds falls as very weak acid known as ‘Acid rain’.
3. What is the nature of acid rain?
a) Withstanding
b) Protecting
c) Corrosive
d) Balancing
View Answer
Explanation: The nature of acid rain is corrosive. This corrosive nature of acid rain produces many forms of environmental damages. It affects rivers, vegetation, soil and organisms. Acid rain is known to cause widespread environmental damage.
4. Which of the following way acid rain affects the plants?
a) By nourishing the nutrients from the soil
b) By increasing the nutrients from the soil
c) By removing nutrients from the soil
d) By balancing the nutrients in the soil
View Answer
Explanation: Acid rain indirectly affects plants by removing nutrients from the soil during which they grow. Acid rain dissolves and washes away all the vitamins in the soil which are very much essential for plants.
5. What is the result of acid rain when it falls into water bodies?
a) The water becomes acidic
b) The water becomes pure
c) The water increase its nutrients value
d) The water increase its level
View Answer
Explanation: When acid rain that falls or flows as water to reach rivers, lakes, wetlands and other water bodies causes the water in them to become acidic. This affects plant and animal life in aquatic ecosystems.
6. Acid rain does not cause any environmental damages.
a) True
b) False
View Answer
Explanation: Acid rain cause many environmental damages. It affects the plants by removing nutrients from the soil. It affects plants and animals life in ecosystem. It affects the food chain. It damages buildings, vehicles and other systems made from stone or steel.
7. Which one of the way can prevent acid rain?
a) Increase the emission of sulfur dioxide and nitrogen oxides
b) Decrease the emission of sulfur dioxide and nitrogen oxides
c) Increase in the emission of hydrochloride and phosphate
d) Decrease in the emission of hydrochloride and phosphate
View Answer
Explanation: One of the ways to stop the formation of acid rain is to decrease the emission of sulfur dioxide and nitrogen oxides into the surroundings. This may be achieved by using much less energy from fossil fuels in power plants and in industries.
8. The Taj Mahal in India is affected by____________________
a) Fog
b) Acid rain
c) Water pollution
d) Spoil Pollution
View Answer
Explanation: Acid rain and dry acid deposition damage buildings. The acid corrodes the materials causing extensive damage and ruins historic buildings. For instances the Tai Mahal in India have been affected by acid rain.
9. Which of the following is the best way to reduce acid rain in soil?
a) By adding sulphur to the soil
b) By adding nitrogen to the soil
c) By adding oxygen to the soil
d) By adding limestone to the soil
View Answer
Explanation: When acid rain affects the soil it’s difficult to prevent soil from acid rain but powered limestone can be added to the soil by a process which is known as liming to neutralize the acidity of the soil.
10. How can we control acid rain which is causing due to the exhaust fumes on the atmosphere by cars?
a) By burning more fuels
b) By using old engine vehicles
c) By using ignition
d) By using catalytic converters
View Answer
Explanation: In catalytic converters, the gases are passed over metal coated beds that convert harmful chemicals into less harmful ones. These are used in cars to reduce the effects of exhaust fumres on the atmosphere.
11. Which is the most acidic in pH scale?
a) 0
b) 7
c) 10
d) 14
View Answer
Explanation: Acidity is measured using a scale called the pH scale. This scale goes from 0 to 14. 0 is the most acidic and 14 is the most alkaline. Acid rain is much weaker than the string acids, it’s never acidic enough to burn the skin.
12. Who was the first to use the phrase “Acid Rain”?
a) Robert Angus Smith
b) Ernest Flower
c) Elmer Joseph Clark
d) Christ Ralph
View Answer
Explanation: The phrase acid rain was first used in 1852 by Robert Angus Smith, who was a Scottish chemist. In his investigation of rainwater chemistry near industrial cities in England and Scotland he termed the phrase acid rain for the very first time.
13. When was the “Clean Air Act” in United States came into force?
a) 1950
b) 1960
c) 1970
d) 1980
View Answer
Explanation: In the United States, reduction in acid deposition stem for the Clean Air Act of 1970 and its Amendments in 1990. This Amendments begun by the regulating of coal fired power plant emission. This development significantly reduced the Sulphuric dioxide in United States.
14. Natural sources also cause acid rain.
a) True
b) False
View Answer
Explanation: The major natural causing agent for acid rain is volcanic emission. Volcanoes emit acid producing gases to create higher than normal amounts of acid rain or any other form of precipitation such as fog and snow.
