It further states that this amount is greater than the total plastic production of the entire last century. Among the options provided, the closest number that fits this description is 10 years. Therefore, the correct answer is 10.
3.
Unless incinerated, most plastics never completely break down.
Correct Answer
A. True
Explanation
Plastics are synthetic materials made from polymers that are not easily biodegradable. They can take hundreds of years to decompose, if at all, when left in the environment. Incineration is one of the few ways to effectively break down plastics, but this process also releases harmful pollutants into the air. Therefore, it is true that unless incinerated, most plastics never completely break down.
4.
Plastic is useful in many ways, but what does it NOT do thus causing pollution?
Correct Answer
A. Biodegrade
Explanation
Plastic is known for its durability and resistance to natural decomposition processes. Unlike organic materials, plastic does not biodegrade, meaning it cannot be broken down by bacteria or other living organisms. This inability to biodegrade is a major factor contributing to plastic pollution in the environment. Plastic waste persists for hundreds of years, causing significant harm to ecosystems and wildlife.
5.
When was plastic invented, which is now a main source of pollution?
Correct Answer
C. Early 20th century
Explanation
Plastic was invented in the early 20th century, making it a main source of pollution. This invention revolutionized various industries and brought convenience to everyday life. However, due to its durability and resistance to degradation, plastic waste has become a significant environmental issue, polluting land, water bodies, and harming wildlife. The early 20th century marked the beginning of the widespread use of plastics, leading to the current pollution crisis we face today.
6.
Which is the first state of India to ban Plastic bottle, disposable foam products?
Correct Answer
B. Sikkim
Explanation
Sikkim is the first state in India to ban plastic bottles and disposable foam products. This means that the use, production, and sale of these items are prohibited in the state. This ban is a significant step towards reducing plastic waste and promoting environmental sustainability. Sikkim's initiative serves as an example for other states and countries to follow in order to combat the growing plastic pollution problem.
7.
What was the major cause of pollution of TTZ
Correct Answer
A. Mathura refinery
Explanation
The major cause of pollution in the TTZ (Taj Trapezium Zone) was the Mathura refinery. The refinery is known for releasing harmful pollutants into the air and water, which significantly contributes to the pollution in the area. This pollution has negative impacts on the environment and the health of the people living in the TTZ.
8.
Which river got polluted due to discharge from National fertilizer’s Naya nangal plant
Correct Answer
B. Sutlej
Explanation
The correct answer is Sutlej. The pollution in the river Sutlej was caused by the discharge from the National Fertilizer's Naya Nangal plant.
9.
Which country has become the first to adopt a ban on deforestation and stop clear-cutting of trees?
Correct Answer
D. Norway
Explanation
Norway has become the first country to adopt a ban on deforestation and stop clear-cutting of trees. This means that Norway has implemented measures to prevent the cutting down of trees and the destruction of forests, which are crucial for maintaining biodiversity, mitigating climate change, and providing valuable ecosystem services. By taking this step, Norway is setting an important example for other countries to follow in order to protect and preserve their forests.
10.
According to Ellen MacArthur's research, by 2050 the ocean will contain more plastic by weight than ______?
Correct Answer
C. Fish
Explanation
According to Ellen MacArthur's research, by 2050 the ocean will contain more plastic by weight than fish. This suggests that the amount of plastic pollution in the ocean is increasing at an alarming rate and poses a significant threat to marine life and ecosystems. The excessive use of single-use plastics and improper waste management contribute to this problem, highlighting the urgent need for global action to reduce plastic waste and protect the health of our oceans.
11.
How long does it take a monofilament (single) fishing line to degrade in the ocean?
Correct Answer
D. 500 Years
Explanation
The correct answer is 500 Years. Monofilament fishing lines are made from synthetic materials like nylon, which are very durable and resistant to degradation. When these lines are discarded or lost in the ocean, they can persist for a long time before breaking down. The slow degradation of monofilament fishing lines is a significant environmental concern as they can entangle marine life, causing injury or death. It is crucial to properly dispose of fishing lines and use more sustainable alternatives to minimize their impact on the ocean ecosystem.
12.
Which of the following is used to make CD
Correct Answer
C. Polycarbonate
Explanation
Polycarbonate is used to make CDs because it is a strong, transparent, and durable material. It has excellent optical properties, allowing for high-quality data storage and retrieval. Polycarbonate also has a high melting point, making it suitable for the manufacturing process of CDs. Additionally, it is resistant to heat, chemicals, and scratches, ensuring the longevity of the CD.
13.
What does the number indicates in the image
Correct Answer
C. Polystyrene foam
Explanation
The number in the image indicates the type of plastic used for the product. In this case, the number is not provided, so we cannot determine the specific type of plastic.
14.
Three Mile Island was the site of what disaster?
Correct Answer
C. The worst accident in US nuclear reactor history
Explanation
The correct answer is "The worst accident in US nuclear reactor history." This is because Three Mile Island was the site of a nuclear accident that occurred on March 28, 1979. It was the most serious accident in the history of the American commercial nuclear power generating industry, where a partial meltdown of the reactor core occurred. While it did not result in any immediate deaths or injuries, it had a significant impact on public perception and the future development of nuclear power in the United States.
15.
A(n) _______________ is specially designed to safely hold municipal solid waste, construction debris, and some types of agricultural and industrial waste.
Correct Answer
A. sanitary landfill
Explanation
A sanitary landfill is a specially designed facility that is built to safely hold various types of waste, including municipal solid waste, construction debris, and certain types of agricultural and industrial waste. Unlike an open dump or waste pit, a sanitary landfill is constructed with specific engineering features and environmental controls to prevent contamination of the surrounding soil, water, and air. It employs techniques such as compacting and covering the waste with soil to minimize odor, pests, and the spread of diseases. Therefore, a sanitary landfill is the correct answer as it meets the criteria of being specially designed and safe for holding different types of waste.
