Renewable And Non-renewable Energy.
Questions and Answers
- 1.
A renewable energy source is one that can replace itself __________ and __________.
- A.
Slowly
- B.
Quickly
- C.
Sometimes
- D.
Dependably
Correct Answer(s)
B. Quickly
D. DependablyExplanation
A renewable energy source is one that can replace itself quickly and dependably. This means that the source can be replenished at a fast rate and consistently, ensuring a continuous supply of energy. This is in contrast to non-renewable energy sources, such as fossil fuels, which take millions of years to form and cannot be replaced within a human lifespan. By being able to replace itself quickly and dependably, renewable energy sources offer a sustainable and reliable solution to meet our energy needs while reducing environmental impact.Rate this question:

A renewable energy source can ___________ be used up.
Correct Answer(s)
neverExplanation
Renewable energy sources, such as solar, wind, and hydro power, are naturally replenished and can be harnessed indefinitely. Unlike finite resources like fossil fuels, which can be depleted over time, renewable energy sources are constantly available and will never run out. This makes them a sustainable and environmentally friendly option for meeting our energy needs.Rate this question:

How long will the sun continue to replenish its energy?
- A.
7,000,000 years
- B.
7,000,000,000 years
- C.
70,000 years
Correct Answer
B. 7,000,000,000 yearsExplanation
The sun will continue to replenish its energy for approximately 7,000,000,000 years. This is based on the estimated lifespan of a star like the sun, which is determined by its mass and energy production through nuclear fusion. The sun is currently in the middle of its main sequence phase, where it fuses hydrogen into helium. As it exhausts its hydrogen fuel, it will expand into a red giant and eventually shed its outer layers, becoming a white dwarf. This entire process is expected to take about 7 billion years.Rate this question:

Which of the following are renewable energy sources?
- A.
Solar
- B.
Gas
- C.
Coal
- D.
Nuclear
- E.
Wind
- F.
Water
Correct Answer(s)
A. Solar
E. Wind
F. WaterExplanation
Solar, wind, and water are considered renewable energy sources because they are naturally replenished and can be used indefinitely without depleting their resources. Solar energy is derived from the sun's rays, wind energy is harnessed from the wind, and water energy is obtained from flowing or falling water. On the other hand, gas, coal, and nuclear energy sources are non-renewable as they are finite and will eventually run out.Rate this question:

How many times can fossil fuels be burnt?
- A.
Twice
- B.
Lots of times
- C.
Once
Correct Answer
C. OnceExplanation
Fossil fuels can be burnt only once. Once they are burned, they are consumed and cannot be used again for combustion. Fossil fuels are non-renewable resources, meaning they are finite and take millions of years to form. Therefore, it is important to find alternative and sustainable sources of energy to reduce our dependence on fossil fuels and minimize their environmental impact.Rate this question:

Fossil fuels might be made from dinosaurs?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Fossil fuels are not made directly from dinosaurs. They are formed from the remains of ancient plants and animals, including microscopic organisms, that lived millions of years ago. Over time, these organic materials were subjected to heat and pressure, leading to the formation of fossil fuels such as coal, oil, and natural gas. While dinosaurs were part of the ancient ecosystem, the majority of fossil fuels come from organisms that lived long before dinosaurs existed. Therefore, it is incorrect to say that fossil fuels are made from dinosaurs.Rate this question:

Are fossil fuels renewable or non-renewable?
- A.
Non-renewable
- B.
Renewable
Correct Answer
A. Non-renewableExplanation
Fossil fuels are considered non-renewable because they are formed from the remains of plants and animals that lived millions of years ago. These resources take a very long time to form, and the rate at which we are consuming them far exceeds their natural replenishment rate. Once fossil fuels are depleted, they cannot be easily replaced within a human lifespan. Therefore, they are classified as non-renewable resources.Rate this question:

What are the three main fossil fuels?
- A.
Electricity
- B.
Gas
- C.
Coal
- D.
Geothermal
- E.
Oil
Correct Answer(s)
B. Gas
C. Coal
E. OilExplanation
The three main fossil fuels are gas, coal, and oil. Fossil fuels are formed from the remains of ancient plants and animals that have been buried and subjected to heat and pressure over millions of years. Gas, coal, and oil are all derived from organic matter and contain carbon and hydrocarbons. These fuels are burned to release energy and are widely used for electricity generation, heating, transportation, and industrial processes.Rate this question:
