Deforestation is the removal of trees from forests. Which of the following is an effect of deforestation?
- A.
Thinning of the ozone layer
- B.
Global warming
- C.
Acid Rain
- D.
Haze and smog
Correct Answer
B. Global warmingExplanation
Deforestation leads to global warming because trees play a crucial role in absorbing carbon dioxide from the atmosphere through the process of photosynthesis. When trees are removed, there is a decrease in the amount of carbon dioxide being absorbed, resulting in higher levels of this greenhouse gas in the atmosphere. This increase in carbon dioxide traps heat from the sun, leading to a rise in global temperatures and contributing to global warming.Rate this question:

Which of the following substances is the cause if eutrophication?
- A.
Carbon dioxide
- B.
Herbicides
- C.
Fertilizers
- D.
Pesticiides
Correct Answer
C. FertilizersExplanation
Fertilizers are the cause of eutrophication. Eutrophication occurs when excess nutrients, such as nitrogen and phosphorus, enter water bodies. Fertilizers, which are commonly used in agriculture, contain high levels of these nutrients. When it rains or irrigation water runs off from fields treated with fertilizers, the excess nutrients enter nearby water bodies. This leads to an overgrowth of algae and other aquatic plants, which depletes oxygen levels in the water. As a result, fish and other aquatic organisms may die, disrupting the natural balance of the ecosystem.Rate this question:

Which of the following diseases become worse when air pollution occurs?
- A.
Bronchitis
- B.
Anaemia
- C.
Asthma
- D.
Heart Attack
Correct Answer
C. AsthmaExplanation
Asthma is a chronic respiratory condition that causes inflammation and narrowing of the airways, leading to difficulty in breathing. Air pollution, such as smog and particulate matter, can irritate and trigger asthma symptoms, making the condition worse. These pollutants can exacerbate inflammation in the airways, causing increased mucus production and constriction of the bronchial tubes. This can result in wheezing, coughing, shortness of breath, and chest tightness. Therefore, asthma is the disease that becomes worse when air pollution occurs.Rate this question:

Which of the following diseases become worse when air pollution occurs?
- A.
Bronchitis
- B.
Anaemia
- C.
Asthma
- D.
Heart Attack
Correct Answer
C. AsthmaExplanation
Asthma becomes worse when air pollution occurs because pollutants in the air can irritate and inflame the airways, making it harder for individuals with asthma to breathe. These pollutants can trigger asthma symptoms such as coughing, wheezing, and shortness of breath. The particles in air pollution can also worsen the inflammation in the airways, leading to more frequent and severe asthma attacks. Therefore, individuals with asthma are particularly vulnerable to the effects of air pollution and may experience worsening of their symptoms when exposed to polluted air.Rate this question:

Which of the following causes the greenhouse effect and global warming?
- A.
The production of gas from the burning of fuel that can become an acid when it reacts with rain.
- B.
The production of a lot of carbon dioxide gas that causes infrared rays from the sun to be trapped.
- C.
The discharge of excessive fertilizers into lake encourages eutrophication.
- D.
The absorption of sunlight and its convertion into heat energy.
Correct Answer
B. The production of a lot of carbon dioxide gas that causes infrared rays from the sun to be trapped.Explanation
The correct answer is the production of a lot of carbon dioxide gas that causes infrared rays from the sun to be trapped. This is because carbon dioxide is a greenhouse gas that can absorb and trap heat in the Earth's atmosphere, leading to the greenhouse effect and global warming. When there is an excess amount of carbon dioxide in the atmosphere, it prevents the escape of infrared radiation, causing the Earth's temperature to rise.Rate this question:

Which of the following atoms reacts with the ozone molecule and causes the destruction of the ozone layer?
- A.
Oxygen
- B.
Carbon dioxide
- C.
Chlorine
- D.
Fluorine
Correct Answer
C. ChlorineExplanation
Chlorine is the correct answer because it is a highly reactive atom that can easily break down ozone molecules. When chlorine reacts with ozone, it forms chlorine monoxide (ClO) and oxygen (O2), which leads to the destruction of the ozone layer. This reaction is a major concern as it contributes to ozone depletion and allows harmful ultraviolet (UV) radiation to reach the Earth's surface.Rate this question:

The following statements describe an undesirable effect on the environment which is caused by human activities.
- Iron railings and stone status corrode faster than normal
- The soil becomes very acidic and unsuitable for the cultivation of crops
- A.
Acid rain
- B.
Soil erosion
- C.
Global warming
- D.
Eutrophication
Correct Answer
A. Acid rainExplanation
The given statements describe two effects on the environment: iron railings and stone statues corrode faster than normal, and the soil becomes very acidic and unsuitable for crop cultivation. These effects are consistent with the phenomenon of acid rain. Acid rain is caused by human activities such as burning fossil fuels, which release pollutants like sulfur dioxide and nitrogen oxide into the atmosphere. These pollutants react with water vapor in the air to form acids, which then fall to the ground as acid rain. Acid rain can corrode metals and stone, and the acidic soil it creates can harm plant growth.Rate this question:

Which of the following has a negative effect on the environment but is not caused by human activity?
- A.
Deforestation
- B.
Volcanic eruption
- C.
Overuse of fertilizers
- D.
Burning of fossil fuels
Correct Answer
B. Volcanic eruptionExplanation
Volcanic eruptions have a negative effect on the environment but are not caused by human activity. During an eruption, large amounts of ash, gases, and lava are released into the atmosphere, which can have detrimental effects on air quality, climate, and ecosystems. The ash and gases can block sunlight, leading to a decrease in temperature and affecting plant growth. Additionally, volcanic gases such as sulfur dioxide can react with water vapor in the atmosphere, forming acid rain that can harm aquatic life and vegetation. Volcanic eruptions can also cause landslides, tsunamis, and the destruction of habitats.Rate this question:

What is the main cause that leads to the extinction of leatherback turtles?
- A.
Poaching
- B.
Collection of their eggs
- C.
High mortality rate of the young turtles
- D.
Accidentally consume plastics that dumped into sea
Correct Answer
D. Accidentally consume plastics that dumped into seaExplanation
The main cause that leads to the extinction of leatherback turtles is their accidental consumption of plastics that are dumped into the sea. Plastics are often mistaken for food by the turtles, and when ingested, they can cause blockages, internal injuries, and even death. This problem is particularly harmful to leatherback turtles because they primarily feed on jellyfish, which can resemble plastic bags or other debris in the water. The ingestion of plastics not only directly harms the turtles but also disrupts their digestive system and overall health, making them more vulnerable to other threats and reducing their chances of survival.Rate this question:

Which of the following is a non biodegradable material?
- A.
Debris of rubbish
- B.
Polystyrene
- C.
Egg shell
- D.
Recycles paper
Correct Answer
B. PolystyreneExplanation
Polystyrene is a non biodegradable material because it cannot be broken down and decomposed by natural processes. Unlike organic materials such as egg shells and recycled paper, which can be broken down by bacteria and other microorganisms, polystyrene remains in the environment for a long time, causing pollution and harm to ecosystems. The debris of rubbish is a vague option and does not provide enough information to determine if it is biodegradable or not.Rate this question:

Which of the following is a non renewable energy source?
- A.
Fossil fuels
- B.
Solar
- C.
Biomass
- D.
Wind
Correct Answer
A. Fossil fuelsExplanation
Fossil fuels are considered a non-renewable energy source because they are formed from the remains of plants and animals that lived millions of years ago. These fuels, such as coal, oil, and natural gas, take a very long time to form and cannot be replenished within a human lifespan. Once these resources are depleted, they cannot be easily replaced. In contrast, solar, biomass, and wind energy are considered renewable because they are derived from natural sources that can be replenished over time.Rate this question:

- A.
Practice 3R (Reduce, Reuse and Recycle)
- B.
Use nets with certain mesh size
- C.
Indiscriminate cutting of trees should be not prohibited
- D.
Practice selective cutting
Correct Answer
C. Indiscriminate cutting of trees should be not prohibitedExplanation
The given answer states that "Indiscriminate cutting of trees should be not prohibited" is not a step to conserve and preserve the environment and wildlife. This means that allowing indiscriminate cutting of trees is not a conservation measure. However, in reality, indiscriminate cutting of trees can lead to deforestation, habitat loss, and negatively impact wildlife populations. Therefore, it is incorrect to suggest that not prohibiting indiscriminate cutting of trees is a step towards conservation and preservation.Rate this question:
