1.
A black rock burned to make electricity is
Correct Answer
D. Coal
Explanation
Coal is the correct answer because it is a black rock that can be burned to generate electricity. Coal is a fossil fuel that is formed from the remains of plants that lived and died millions of years ago. When coal is burned, it releases energy in the form of heat, which can be used to produce steam and drive turbines to generate electricity. Coal is one of the most widely used sources of electricity generation due to its abundance and relatively low cost.
2.
Energy from heat inside the earth is
Correct Answer
B. Geothermal
Explanation
Geothermal energy refers to the heat stored within the Earth's crust, which can be harnessed and converted into usable energy. This heat originates from the Earth's core and is a natural and renewable resource. Natural gas and petroleum, on the other hand, are fossil fuels that are formed from the remains of ancient plants and animals. Terrathermal is not a recognized term in the context of energy sources. Therefore, the correct answer is geothermal, as it specifically relates to the energy derived from heat inside the Earth.
3.
Energy from flowing water is
Correct Answer
A. Hydropower
Explanation
Hydropower is the correct answer because it refers to the energy generated from flowing water. It is a renewable energy source that harnesses the power of water to generate electricity. This is typically done by using dams or other structures to capture the energy of flowing or falling water, which then drives turbines to produce electricity. Hydropower is a clean and sustainable form of energy that can help reduce dependence on fossil fuels and mitigate climate change.
4.
Energy from wood, waste, and garbage is called
Correct Answer
C. Biomass
Explanation
Biomass refers to the energy derived from organic matter such as wood, waste, and garbage. This organic material is burned or converted into other forms of fuel to generate heat or electricity. Therefore, biomass is the correct term to describe energy obtained from these sources.
5.
Energy from moving air is called
Correct Answer
C. Wind power
Explanation
Wind power refers to the energy generated from the movement of air. This energy is harnessed using wind turbines, which convert the kinetic energy of the wind into electrical energy. Wind power is a renewable and clean source of energy that does not produce greenhouse gas emissions. It is a sustainable alternative to fossil fuels and plays a crucial role in reducing dependence on non-renewable energy sources.
6.
Energy in rays form the sun is called
Correct Answer
A. Solar power
Explanation
The energy in rays from the sun is called solar power. Solar power refers to the conversion of sunlight into electricity or thermal energy. It is a renewable and clean source of energy that can be harnessed through the use of solar panels or solar thermal systems. Solar power is widely used for various applications including generating electricity for homes, businesses, and even powering vehicles. It is an important alternative to fossil fuels, as it helps reduce greenhouse gas emissions and dependence on non-renewable energy sources.
7.
A mixture of gases, that was formed from ancient sea plants and animals is
Correct Answer
B. Natural gas
Explanation
Natural gas is formed from the remains of ancient sea plants and animals that were buried under layers of sediment millions of years ago. Over time, heat and pressure transformed these organic materials into fossil fuels. This process resulted in the formation of natural gas, which is primarily composed of methane. Therefore, natural gas is the correct answer as it is directly derived from the ancient sea plants and animals.
8.
A liquid fuel that was formed from the ancient remains of sea plants and animals is
Correct Answer
B. Petroleum
Explanation
Petroleum is the correct answer because it is a liquid fuel that is formed from the ancient remains of sea plants and animals. Over millions of years, the remains have been subjected to heat and pressure, transforming them into petroleum. This fossil fuel is commonly used for various purposes such as fuel for transportation, heating, and electricity generation.
9.
Which is a list of fossil fuels?
Correct Answer
A. Natural gas, petroleum, coal
Explanation
The correct answer is natural gas, petroleum, coal. These three substances are considered fossil fuels because they are formed from the remains of ancient plants and animals that have been buried and subjected to heat and pressure over millions of years. Natural gas is primarily composed of methane and is often found alongside petroleum deposits. Petroleum, also known as crude oil, is a liquid mixture of hydrocarbons and is the main source of energy for transportation and many industrial processes. Coal is a solid fossil fuel formed from the remains of plants that lived and died millions of years ago.
10.
Which is a list of renewable resources?
Correct Answer
B. Biomass, geothermal, hydropower
Explanation
The correct answer is biomass, geothermal, hydropower. These three options are all examples of renewable resources. Biomass refers to organic materials, such as plants and animal waste, that can be used to produce energy. Geothermal energy is generated from the heat of the Earth's core. Hydropower harnesses the energy from flowing water, such as rivers or waterfalls. These resources are considered renewable because they can be replenished naturally and are not depleted like fossil fuels.
11.
What does renewable mean?
Correct Answer
B. It is a resource that is replaced at the same rate that it is being used.
Explanation
Renewable means that the resource is replaced at the same rate it is being used. This implies that the resource is sustainable and can be continuously replenished, ensuring its availability for future generations. Unlike non-renewable resources, which are formed at a much slower rate than they are consumed, renewable resources can be harnessed without depleting the source. This characteristic makes renewable resources an environmentally friendly and long-term solution to meet our energy and material needs.
12.
What does nonrenewable mean?
Correct Answer
C. It is a resource that is formed at a rate that is much slower than the rate at which it is being used
Explanation
Nonrenewable means that the resource is formed at a much slower rate than it is being used. This implies that the resource cannot be easily replenished or replaced once it is depleted. Examples of nonrenewable resources include fossil fuels like coal, oil, and natural gas, as well as minerals like copper and gold. These resources take millions of years to form, while their extraction and consumption occur at a much faster pace. Therefore, the correct answer is that nonrenewable resources are formed at a slower rate than they are being used.
