Example Question #11 : Formation And Uses Of Energy
A material that is found in nature and helpful to humans is called a ________________.
nutrient resource
natural resource
energy resource
mineral
natural resource
Humans receive many of our resources from nature, and they are called natural resources. These are things like water, trees, and wind that are naturally occurring, and humans can harness their energy to create power for the everyday things we need. Humans will also mine for resources that are naturally occurring so that we can transform them into other necessary products.
Example Question #161 : 4th Grade Science
What does the term "fuel" mean?
Fuel forms from the remains of ocean organisms.
Fuel is the burning of a substance.
Fuel is a renewable resource that is beneficial to the environment.
Fuel is a substance that provides energy as a result of a chemical change.
Fuel is a substance that provides energy as a result of a chemical change.
Fuel is often thought of in terms of gasoline for a car, but it is any substance that provides energy from a chemical change. Food that we eat is turned into energy through our digestive system, so it is also a fuel. Fuel can be for machinery, the body, cars, and other mechanical items. Many of the fuels that we use are nonrenewable and can be harmful to the environment.
Example Question #1 : Describe How Energy And Fuel Are Created
Fossil fuels are nonrenewable resources. They are nonrenewable because they take millions of years to form. Earth’s oil took 500 million years to form. Fossil fuels are formed from the remains of organisms. Fossil fuels are rich in energy. Coal is formed from plant remains that have been buried for millions of years. Coal is the fuel used in many electrical power plants. Oil is a thick, black, liquid fossil fuel. Oil forms from the remains of ocean organisms. Petroleum is another name for oil. Natural gas is a mixture of gases. Natural gas forms from the remains of ocean organisms.
How are fossil fuels created?
Harvested from crops and greenhouses
Cut down from trees and processed
Remains of organisms put under pressure
Grown in a laboratory for many years
Remains of organisms put under pressure
Fossil fuels are all created underground or underwater from the remains of organisms. The short passage explains that they are all nonrenewable and take millions of years to form. Coal is from plants, and oil and natural gas are from ocean organisms. All fossil fuels were once a living thing that were placed under immense amounts of pressure over a long period to create the fuel that we need to run our energy and lives.
Example Question #162 : 4th Grade Science
Which answer choice lists only renewable energy sources?
Water, wind, solar, and thermal power
Natural gas, oil, petroleum, and solar power
Fossil fuels, wood, water, and wind
Solar power, wind, water, and oil
Water, wind, solar, and thermal power
Renewable resources are created by nature and can be reused or regenerated quickly. They cause very little damage to the Earth and can be a cleaner way to generate the energy we need to live. Wind, water, solar, and thermal power are all products of the Earth and are renewable.
Example Question #162 : 4th Grade Science
Which answer choice lists only nonrenewable energy sources?
Oil, wind, coal, and natural gas
Natural gas, oil, petroleum, and coal
Wind, thermal, solar, and water
Water, oil, petroleum, and coal
Natural gas, oil, petroleum, and coal
Nonrenewable energy sources are created when the Earth applies immense amounts of pressure to the remains of organisms buried deep below the surface. The materials must be dug or mined out of the ground and collected to be processed and used. Natural gas, oil, petroleum, and coal are all nonrenewable energy sources that are difficult to replace and will eventually run out.
Example Question #3 : Describe How Energy And Fuel Are Created
Fossil fuels are nonrenewable resources. They are nonrenewable because they take millions of years to form. Earth’s oil took 500 million years to develop. Fossil fuels are formed from the remains of organisms. Fossil fuels are rich in energy. Coal is formed from plant remains that have been buried for millions of years. Coal is the fuel used in many electrical power plants. Oil is a thick, black, liquid fossil fuel. Oil forms from the remains of ocean organisms. Petroleum is another name for oil. Natural gas is a mixture of gases. Natural gas forms from the remains of ocean organisms.
Fossil fuels are used for __________.
plants
coal
oil
energy

Example Question #111 : Earth And Space Science
Iron ore is a resource that is found in many places around the world. Why is iron ore a nonrenewable resource?
Mining iron ore causes pollution and damage to the environment.
Iron ore is difficult to recycle.
Most iron ore has yet to be discovered.
Forming new iron ore is an extremely long process.
Forming new iron ore is an extremely long process.
Iron ore is a nonrenewable resource because it is challenging to replenish due to the amount of time it takes to form. Most of the iron ore that is currently deep within Earth's rocks is 1.8 billion years old. By the time we have used all of the available iron ore, there will not be enough time to generate new materials.
Example Question #111 : Earth And Space Science
How could nonrenewable resources be replaced with renewable resources?
Use hybrid vehicles that cut down on gas usage.
Heat homes with wind-generated power.
Create electricity with solar panels instead of coal.
All of the answer choices are correct.
Generate power for a town with hydroelectric methods.
All of the answer choices are correct.
Nonrenewable resources are those found on Earth or within Earth's surface and take millions if not billions of years to form and replenish themselves, such as oil, petroleum, and coal. Renewable resources are generated by sources that cannot run out and do not need replenishing like the Sun, water, or wind. All of the answer choices provide good options for replacing nonrenewable resources with something renewable.
Example Question #113 : Earth And Space Science
Which renewable resource is replenished by evaporation, condensation, and precipitation?
Water
Wind
Oxygen
Petroleum
Water
Water is a renewable resource that is renewed by evaporation, condensation, and precipitation. These are all stages of the water cycle, which is continually replenishing the water on Earth. Water is a resource that has power when it is in motion and we can harness this to generate electricity.
Example Question #111 : Earth And Space Science
Which resource would be more plentiful to people who live in the southern United States than it would be for people who live in the northeastern parts of the United States?
Oil
Solar energy
Gas
Wind energy
Solar energy
Solar energy would be more plentiful to people in the southern US than those in the northeastern parts of the US because of the amount of sunlight each area receives. The northeast areas receive lots of rainy, snowy, dark days while the southern US has more days with sunshine.
