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.

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.

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.

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.

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.

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.

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.

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.

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.
