- 1.
Skateboard rolling downhill is an example of what form of energy?
- A.
Chemical energy
- B.
Electromagnetic energy
- C.
Mechanical energy
Correct Answer
C. Mechanical energyExplanation
When a skateboard rolls downhill, it is converting potential energy (stored energy due to its position on the hill) into kinetic energy (energy of motion). This conversion is an example of mechanical energy, which is the energy possessed by an object due to its motion or position.Rate this question:

Lightning during a thunderstorm is an example of what form of energy?
- A.
Thermal energy
- B.
Electrical energy
- C.
Chemical energy
Correct Answer
B. Electrical energyExplanation
Lightning during a thunderstorm is an example of electrical energy because it is the result of a buildup and discharge of electrical charges in the atmosphere. This discharge creates a powerful electrical current that we see as a bolt of lightning.Rate this question:

Energy stored in food is an example of what form of energy?
- A.
Thermal energy
- B.
Chemical energy
- C.
Electrical energy
Correct Answer
B. Chemical energyExplanation
The energy stored in food is an example of chemical energy because it is stored in the chemical bonds of molecules within the food. When the food is digested and broken down, these bonds are broken, releasing the stored energy. This energy is then used by the body for various processes such as movement, growth, and maintaining body temperature.Rate this question:

Heat given off by a fire is an example of what form of energy?
- A.
Mechanical energy
- B.
Thermal energy
- C.
Nuclear energy
Correct Answer
B. Thermal energyExplanation
The heat given off by a fire is an example of thermal energy. Thermal energy refers to the internal energy of an object or substance due to the motion and vibration of its particles. In the case of a fire, the heat is produced by the combustion of fuel, which causes the particles to move and vibrate rapidly, generating thermal energy.Rate this question:

Solar energy is energy from the sun.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Solar energy refers to the energy that is harnessed from the sun. This energy can be converted into electricity or used directly for various purposes such as heating, lighting, and powering devices. Solar panels and other solar technologies are designed to capture the sun's rays and convert them into usable energy. Therefore, the statement "Solar energy is energy from the sun" is true, as it accurately describes the source and nature of solar energy.Rate this question:

PV cells turn light from the sun into heat.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
PV cells, or photovoltaic cells, do not turn light from the sun into heat. Instead, they convert sunlight directly into electricity through a process called the photovoltaic effect. When sunlight hits the PV cell, it excites electrons in the material, creating an electric current. This electricity can then be used to power various devices or stored in batteries. Therefore, the correct answer is False.Rate this question:

Wind power works by having the wind turn a turbine to produce electricity.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Wind power harnesses the kinetic energy of the wind to generate electricity. This is achieved by using wind turbines, which consist of blades that spin when the wind blows. The spinning motion of the blades activates a generator, converting the mechanical energy into electrical energy. Therefore, it is true that wind power works by having the wind turn a turbine to produce electricity.Rate this question:

Hydropower (moving water) works by getting electrons out of the water.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Hydropower works by harnessing the kinetic energy of moving water to generate electricity, not by extracting electrons from the water. The movement of water, such as from a river or dam, spins a turbine which is connected to a generator, converting the mechanical energy into electrical energy. Therefore, the given statement is false.Rate this question:

Geothermal energy can be used anywhere on Earth.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Geothermal energy cannot be used anywhere on Earth. It requires specific geological conditions, such as the presence of underground heat sources and permeable rock formations, which are not available everywhere. Therefore, the statement is false.Rate this question:
-
- 11.
Geothermal energy produces very little or no pollution.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Geothermal energy is generated by harnessing the heat from the Earth's core, which is a clean and renewable source of energy. Unlike fossil fuels, geothermal energy does not produce greenhouse gas emissions or air pollutants when used for electricity generation. Therefore, it can be concluded that geothermal energy produces very little or no pollution, making the answer "True" correct.Rate this question:

Trees (or wood) are the most common form of biomass in most areas.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Trees are indeed the most common form of biomass in most areas. Biomass refers to organic matter, such as plants, that can be used as a renewable energy source. Trees are widely available and easily accessible in many regions, making them a prevalent source of biomass. They can be used for various purposes, including fuel, heating, and electricity generation. Additionally, trees are renewable resources as they can be replanted and grown again, making them an environmentally friendly option for biomass production.Rate this question:

Oil is usually formed from the remains of living things that lived in the _____________.
Correct Answer
ocean
sea
waterExplanation
Oil is usually formed from the remains of living things that lived in the ocean, sea, or water. This is because the process of oil formation, known as fossilization, occurs when organic matter such as algae and plankton accumulate on the ocean floor and are subjected to heat and pressure over millions of years. As a result, the organic matter undergoes chemical changes and transforms into oil. Therefore, oil can be found in various bodies of water, including the ocean and sea.Rate this question:

_____________ transport natural gas from its source to where it's used.
Correct Answer
pipes
pipelinesExplanation
Pipes and pipelines are used to transport natural gas from its source to where it is used. Both terms refer to a system of interconnected tubes or conduits that allow for the safe and efficient transportation of natural gas over long distances. These pipes or pipelines are designed to withstand the high pressure and flow rate of the gas, ensuring that it reaches its destination without any leaks or loss. Therefore, both pipes and pipelines are essential infrastructure components in the natural gas industry.Rate this question:
- 15.
Coal is a ____________ fossil fuel formed from plant remains.
- A.
Liquid
- B.
Solid
- C.
Gas
Correct Answer
B. SolidExplanation
Coal is a solid fossil fuel formed from plant remains. Over millions of years, the remains of plants have undergone a process called coalification, where heat and pressure cause the organic material to transform into solid coal. This solid form of coal is widely used as a source of energy due to its high carbon content and ability to generate heat when burned.Rate this question:
