Check all examples of nonrenewable resources.
- A.
Fossil fuels
- B.
Trees
- C.
Oil
- D.
Metals like iron, gold and silver
Correct Answer(s)
A. Fossil fuels
C. Oil
D. Metals like iron, gold and silverExplanation
The correct answer includes fossil fuels, oil, and metals like iron, gold, and silver. Fossil fuels are nonrenewable resources because they are formed over millions of years from the remains of plants and animals. Oil is also a nonrenewable resource as it takes millions of years to form from the remains of marine organisms. Metals like iron, gold, and silver are nonrenewable because they are extracted from the earth's crust and their supply is limited. Trees, on the other hand, are renewable resources as they can be replanted and regrown.Rate this question:

What 2 gases produce acid rain?
- A.
Nitrogen and sulfur
- B.
Sulfur and magnesium
- C.
Magnesium and nitrogren
- D.
Nitrogen and oxygen
Correct Answer
A. Nitrogen and sulfurExplanation
Nitrogen and sulfur are the two gases that produce acid rain. When fossil fuels are burned, nitrogen oxides and sulfur dioxide are released into the atmosphere. These gases then react with water, oxygen, and other chemicals to form nitric acid and sulfuric acid, which are the main components of acid rain. Acid rain can have harmful effects on the environment, including damaging forests, lakes, and buildings.Rate this question:

Trace the transformation of energy for hydroelectricity.
- A.
Kinetic - potential - hydroelectricity
- B.
Kinetic - mechanical - hydroelectricity
- C.
Potential - mechanical - hydroelectricity
- D.
Water - dam - house
Correct Answer
B. Kinetic - mechanical - hydroelectricityExplanation
The transformation of energy for hydroelectricity starts with the kinetic energy of flowing water. This kinetic energy is then converted into mechanical energy as the water spins the turbine. Finally, the mechanical energy is transformed into hydroelectricity through the generator, which produces electrical energy. Therefore, the correct sequence is kinetic - mechanical - hydroelectricity.Rate this question:

- D.
It is tited
Correct Answer
A. It can never run outExplanation
The term "inexhaustible" refers to something that cannot run out or be depleted. In this context, it means that the resource in question will never come to an end or be exhausted. It implies that the resource is limitless and can be used continuously without the fear of it running out.Rate this question:

- A.
It can never run out
- B.
Once it is gone it is gone forever - it can not be replaced in a lifetime
- C.
It can be replaced or replenished
- D.
It is tired
Correct Answer
B. Once it is gone it is gone forever - it can not be replaced in a lifetimeExplanation
Nonrenewable resources are natural resources that cannot be replaced or replenished once they are depleted. Unlike renewable resources, which can be naturally restored over time, nonrenewable resources have a finite supply. Once these resources, such as fossil fuels or minerals, are exhausted, they cannot be regenerated within a human lifespan. This makes it crucial to manage and conserve nonrenewable resources wisely to ensure their sustainable use and prevent future scarcity.Rate this question:

Energy from running water is used to generate ___________________________/
- A.
Biomass
- B.
Wind energy
- C.
Solar power
- D.
Hydroelectricity
Correct Answer
D. HydroelectricityExplanation
Hydroelectricity is generated by harnessing the energy from running water. This process involves the use of dams or other structures to capture the kinetic energy of flowing water and convert it into electrical energy. The force of the water turns turbines, which then spin generators to produce electricity. Therefore, hydroelectricity is the correct answer because it directly relates to the generation of energy from running water.Rate this question:

What is a renewable energy that uses plant and animal waste?
- A.
Solar energy
- B.
Wind power
- C.
Biomass
- D.
Hydroelectricity
Correct Answer
C. BiomassExplanation
Biomass is a renewable energy source that uses plant and animal waste. It involves utilizing organic materials such as wood, crops, agricultural residues, and animal waste to generate heat and electricity. These materials are burned or converted into biogas through processes like anaerobic digestion. Biomass energy helps reduce reliance on fossil fuels, decreases greenhouse gas emissions, and promotes sustainable waste management.Rate this question:

Which is a nonrenewable source of energy?
- A.
Solar
- B.
Wind
- C.
Hydroelectricity
- D.
Coal
Correct Answer
D. CoalExplanation
Coal is a nonrenewable source of energy because it is formed from the remains of plants that lived and died millions of years ago. It takes millions of years for coal to form, making it a finite resource. Once coal is extracted and burned for energy, it cannot be replenished within a human lifespan. Therefore, coal is considered nonrenewable and its use contributes to environmental issues such as air pollution and greenhouse gas emissions.Rate this question:
