1.
What are some renewable energy sources?
Correct Answer
A. Sun, wind, water, and biomass
Explanation
The correct answer is sun, wind, water, and biomass. These are all examples of renewable energy sources. The sun provides solar energy, which can be converted into electricity through solar panels. Wind energy is generated by wind turbines. Water can be used to generate hydroelectric power through dams and turbines. Biomass refers to organic matter that can be burned or converted into fuel, such as wood or agricultural waste, to produce energy. These sources are considered renewable because they are naturally replenished and do not deplete finite resources.
2.
What happens to the atmosphere when fossil fuels are used?
Correct Answer
B. The Co2 released from burning these go into the atmospHere and make it thicker making sun rays trapped with in the atmospHere
Explanation
When fossil fuels are burned, they release carbon dioxide (CO2) into the atmosphere. This increase in CO2 levels thickens the atmosphere, causing the sun rays to get trapped within it. This phenomenon is known as the greenhouse effect, and it leads to global warming and climate change.
3.
What happens if we keep using non renewable resources?
Correct Answer
D. We will eventually run out of the resources
Explanation
If we continue to use non-renewable resources, such as fossil fuels, without finding alternative sources or implementing sustainable practices, we will eventually deplete these resources. Non-renewable resources are finite and take millions of years to form, so once they are used up, they cannot be replenished within a human lifespan. This can lead to energy shortages, environmental degradation, and economic instability. Therefore, it is crucial to transition towards renewable energy sources and adopt sustainable practices to ensure a stable and sustainable future.
4.
What is the key difference between non renewable and renewable resources?
Correct Answer
C. Non renewable runs out and will never replenish itself or take a long time to replenish, but renewable resources constantly replenish itself
Explanation
Non-renewable resources, such as fossil fuels, have a finite supply and once they are depleted, they cannot be replenished within a reasonable timeframe. On the other hand, renewable resources, like solar or wind energy, are constantly replenished by natural processes and can be used indefinitely without running out. This key difference highlights the sustainability of renewable resources and the limited availability of non-renewable resources.
5.
Uranium is a renewable resource
Correct Answer
B. False
Explanation
Uranium is not a renewable resource. It is a finite resource that is extracted from the Earth's crust. Once it is used in nuclear reactors or weapons, it cannot be reused or replenished. Therefore, the correct answer is False.
6.
What are some consequences of making water power.
Correct Answer
A. The dam required to create water power uses a lot of energy and materials, it can cause earthquakes, floods, and bring malaria carrying mosquitoes
Explanation
Constructing a dam for water power generation requires a significant amount of energy and materials, which can have negative environmental consequences. The weight of the water behind the dam can cause increased pressure on the Earth's crust, potentially leading to earthquakes. Moreover, if the dam is not properly managed, it can result in flooding. Stagnant water in the reservoir can also become a breeding ground for mosquitoes carrying diseases like malaria.
7.
What is NOT a benefit of using solar energy?
Correct Answer
A. It costs a lot.
Explanation
Using solar energy is beneficial in many ways. It is environment friendly as it does not create CO2 that can thicken the atmosphere. Additionally, the sun is the major source of energy on earth, making solar power a renewable and abundant resource. However, the statement "It costs a lot" is not a benefit of using solar energy. This suggests that using solar energy may be expensive compared to other energy sources.
8.
Is everyone being affected by global warming?
Correct Answer
A. Yes
Explanation
Global warming is a global phenomenon that affects the entire planet. It is caused by the increase in greenhouse gases, primarily carbon dioxide, in the Earth's atmosphere. These gases trap heat and cause the Earth's temperature to rise, leading to various negative impacts such as melting ice caps, rising sea levels, extreme weather events, and ecosystem disruption. As global warming is a worldwide issue, it affects everyone, regardless of their geographical location or socioeconomic status. Therefore, the correct answer is "yes."
9.
Paris agreement is related to
Correct Answer
A. Climate change
Explanation
The Paris Agreement is an international treaty that aims to combat climate change by reducing greenhouse gas emissions and supporting countries in adapting to the impacts of climate change. It was adopted in 2015 and has been ratified by almost all countries. The agreement sets out goals to limit global warming to well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 degrees Celsius. It also establishes a framework for countries to regularly report on their emissions and progress towards their climate goals. Therefore, the Paris Agreement is directly related to climate change.
10.
Minimata convention covers which pollutant
Correct Answer
A. Mercury
Explanation
The Minamata Convention covers mercury as a pollutant. This international treaty aims to protect human health and the environment from the harmful effects of mercury. It includes provisions for controlling and reducing mercury emissions, regulating the use and trade of mercury, promoting mercury-free alternatives, and addressing the storage and disposal of mercury waste. The convention was named after the Minamata disease, a neurological disorder caused by mercury poisoning, which occurred in Japan in the mid-20th century.
