1.
What is sulfur dioxide?
Correct Answer
A. Colourless, prudent gas released as a by-product of combusted fossil fuels containing sulfur.
Explanation
Sulfur dioxide is a colorless, pungent gas that is released when fossil fuels containing sulfur are burned. It is a by-product of combustion and can contribute to acid precipitation.
2.
What do SO2 (sulfur dioxide) and NOX (nitrous oxides) make?
Correct Answer
B. Acid rain
Explanation
SO2 (sulfur dioxide) and NOX (nitrous oxides) combine with water vapor in the atmosphere to form sulfuric acid and nitric acid, respectively. These acids then mix with precipitation, resulting in acid rain. Acid rain can have harmful effects on the environment, including damaging forests, lakes, and buildings, and also impacting human health. Therefore, the correct answer is acid rain.
3.
Can acid rain go undetected in an area for years?
Correct Answer
A. Yes
Explanation
Acid rain can go undetected in an area for years because it is often a slow and gradual process. The effects of acid rain on the environment, such as damage to vegetation and aquatic life, may not be immediately noticeable. Additionally, the pH levels in rainwater can vary naturally, making it difficult to distinguish between normal rain and acid rain without proper monitoring equipment. Therefore, acid rain can persist in an area for an extended period without being identified or addressed.
4.
How can you reduce acid rain?
Correct Answer
C. Choice A and B
Explanation
Walking when you can and conserving energy are both ways to reduce acid rain. Walking instead of driving reduces the emissions from vehicles, which contribute to the formation of acid rain. Conserving energy helps to reduce the demand for electricity, which in turn reduces the emissions from power plants that also contribute to acid rain. Therefore, the combination of these two choices, A and B, is the most effective way to reduce acid rain.
5.
Acid rain damages everything over a period of time because it makes the living things in the environment _______
Correct Answer
B. Die
Explanation
Acid rain damages everything over a period of time because it makes the living things in the environment die. Acid rain is formed when pollutants such as sulfur dioxide and nitrogen oxide mix with the atmosphere and fall back to the ground as acidic precipitation. This acidic rainwater can harm plants, animals, and aquatic life by damaging their cells, disrupting their metabolism, and altering the pH levels of their habitats. Over time, these detrimental effects can lead to the death of various organisms, ultimately causing damage to the entire ecosystem.
6.
What causes the acidity in lakes and streams to increase?
Correct Answer
C. Heavy rainstorms
Explanation
Heavy rainstorms can cause the acidity in lakes and streams to increase due to a phenomenon known as acid rain. When rainwater combines with pollutants such as sulfur dioxide and nitrogen oxides from sources like industrial emissions and vehicle exhaust, it forms acidic compounds. These compounds are then deposited onto the earth's surface through rainfall, increasing the acidity of lakes and streams. This can have detrimental effects on aquatic life and ecosystems, as well as on the quality of drinking water.
7.
Acid rain is caused by which of the following?
Correct Answer
D. All of the above
Explanation
Acid rain is caused by the presence of certain pollutants in the atmosphere, such as carbon dioxide, carbon monoxide, and lead. These pollutants are released into the air through various human activities, such as burning fossil fuels and industrial processes. When these pollutants react with water vapor in the atmosphere, they form acids, which then fall to the ground as acid rain. Therefore, all of the above options contribute to the formation of acid rain.
8.
Automobiles release harmful ________ into the air, which causes acid rain.
Correct Answer
A. Smoke
Explanation
Automobiles release harmful smoke into the air, which contains pollutants such as carbon monoxide, nitrogen oxides, and particulate matter. These pollutants can react with water vapor in the atmosphere to form acidic compounds, leading to the formation of acid rain. Acid rain can have detrimental effects on the environment, including damaging forests, aquatic ecosystems, and infrastructure. Therefore, the release of smoke from automobiles contributes to the problem of acid rain.
9.
How can acid rain affect non-living things?
Correct Answer
B. it can decay building materials and paint
Explanation
Acid rain can decay building materials and paint because it contains high levels of acidic substances such as sulfuric and nitric acid. When these acids come into contact with non-living things such as buildings, statues, or vehicles, they can cause corrosion and deterioration over time. This can lead to the degradation of structures, erosion of paint, and damage to various materials.
10.
The atmosphere deposits a lot of toxic metals into the forests because acid rain contains ________.
Correct Answer
C. Metal
Explanation
Acid rain is formed when pollutants such as sulfur dioxide and nitrogen oxides react with water vapor in the atmosphere. These pollutants are primarily emitted from industrial processes and vehicle emissions. When acid rain falls, it can carry and deposit various toxic metals present in the atmosphere, such as mercury, lead, and cadmium, into the forests. These metals can have harmful effects on the ecosystem, including damage to plants, animals, and aquatic life. Therefore, the correct answer is "metal" as it accurately describes the substances deposited by acid rain in the forests.
