1.
Which of these is a non-renewable resource?
Correct Answer
C. Coal
Explanation
Coal is a non-renewable resource because it takes millions of years to form through the decomposition of plant matter. Once coal is extracted and burned for energy, it cannot be replenished within a human lifespan. In contrast, the Sun and Moon are celestial bodies that are not considered resources, and they do not deplete over time.
2.
Which of these is a renewable resource?
Correct Answer
C. Wind
Explanation
Wind is considered a renewable resource because it is constantly replenished by natural processes. Unlike non-renewable resources such as copper, which are finite and will eventually run out, wind energy can be harnessed and used without depleting its source. Wind turbines convert the kinetic energy of the wind into electricity, making it a sustainable and environmentally friendly source of power.
3.
Which of the following lowers your carbon footprint?
Correct Answer
A. Riding a bike to College
Explanation
Riding a bike to college lowers your carbon footprint because it is a form of active transportation that does not emit any greenhouse gases. Unlike driving a car or taking a plane, which both contribute to carbon emissions, riding a bike is a more sustainable and environmentally friendly mode of transportation. By choosing to ride a bike, you are reducing your reliance on fossil fuels and minimizing your impact on climate change.
4.
Which of the following is not an efficient use of energy?
Correct Answer
C. Boiling a full kettle for one cup of tea
Explanation
Boiling a full kettle for one cup of tea is not an efficient use of energy because it requires a large amount of energy to heat up the entire kettle of water, even though only a small amount is needed for one cup of tea. This results in unnecessary energy waste and higher electricity consumption. It would be more efficient to only boil the amount of water needed for one cup, saving both energy and money.
5.
Which one of the following is environmentally friendly?
Correct Answer
C. Sorting items into separate recycling bins
Explanation
Sorting items into separate recycling bins is environmentally friendly because it promotes the proper disposal and recycling of waste materials. By separating different types of items, such as paper, plastic, and glass, it allows for more efficient recycling processes and reduces the amount of waste that ends up in landfills. This practice helps conserve resources, reduce pollution, and minimize the negative impact on the environment.
6.
Which of the following uses the least amount of water?
Correct Answer
B. Showering for 5 minutes in a normal shower
Explanation
Showering for 5 minutes in a normal shower uses the least amount of water compared to the other options. This is because taking a bath requires a larger volume of water to fill the tub, and showering for 10 minutes in a power shower would consume more water due to the increased water pressure. Therefore, showering for a shorter duration in a regular shower is the most water-efficient option.
7.
Which of the following is NOT a key principle of environmental sustainability?
Correct Answer
B. Prioritizing economic growth above all else
Explanation
Environmental sustainability emphasizes a balanced approach where economic development, social progress, and environmental protection are interconnected and equally important. While economic growth is necessary, it should not come at the expense of the environment or social well-being. Sustainable development aims to meet the needs of the present without compromising the ability of future generations to meet their own needs.
8.
Which of the following contributes to climate change?
Correct Answer
B. Fossil Fuels
Explanation
Fossil fuels contribute to climate change because when they are burned, they release large amounts of greenhouse gases such as carbon dioxide into the atmosphere. These gases trap heat and cause the Earth's temperature to rise, leading to global warming and climate change. Flooding, on the other hand, is a consequence of climate change rather than a contributor. Flowers do not directly contribute to climate change as they do not release greenhouse gases.
9.
Which of the following is a way to save water?
Correct Answer
B. Fixing a dripping tap
Explanation
Fixing a dripping tap is a way to save water because a dripping tap can waste a significant amount of water over time. By repairing the tap and stopping the leak, water is conserved and not wasted unnecessarily. This small action can contribute to water conservation efforts and help in reducing water consumption.
10.
Buying food locally is good for the environment because....?
Correct Answer
A. Food travels fewer miles so less fuel is used
Explanation
Buying food locally is good for the environment because it reduces the distance that food has to travel, resulting in less fuel being used. When food is transported over shorter distances, it reduces the carbon emissions associated with transportation. This helps to reduce air pollution and minimize the negative impact on the environment. Additionally, buying locally supports local farmers and the local economy, promoting sustainable farming practices and preserving the countryside.
