Formation and Uses of Energy - 4th Grade Science

There is much debate about the use of fossil fuels because of their effect on the environment. Fossil fuels must be burned to create a chemical reaction, and people are concerned that this creates additional air pollution that will only add to the environmental issues that we currently have. There is a concern about the expense of fossil fuels, but that is not an environmental issue, that is a financial issue.

Coal is a fossil fuel that is nonrenewable and is created throughout millions of years by combining the remains of organisms and applying immense pressure. There are benefits to using coal, but a primary environmental concern is the damage mining causes to wildlife habitats in the areas of the digging. The land is cleared to make room for workers and machinery, and animals are displaced during this time; the earth is left barren adn stripped of many needed minerals, so vegetation becomes limited.

Wind energy is a renewable resource and an increasingly more popular replacement for traditional fossil fuels and power plants. One negative effect that wind energy may have on the environment is noise pollution. There is construction needed to build the wind turbines necessary, which creates noise as well as the maintenance and daily sounds produced by the turbines and generators. Wind energy has many positive effects on the environment as well, so the pros and cons must be weighed to makes decisions about the best energy source.

Petroleum, natural gas, and coal are all nonrenewable resources that require mining and removal from under the Earth’s surface to use for power and energy. These resources are efficient and useful but come at a cost. Heavy machines that pollute the air, deforestation, stripping the ground of nutrients, and the eventual extinction of these supplies are all adverse effects they have on the environment. If we were to switch to renewable resources, there would be less concern for running out of energy sources, less pollution, fewer animal habitats destroyed, less deforestation, and cleaner energy sources available to the public. There are many benefits to switching to alternative fuels and replacing fossil fuels.

Petroleum, natural gas, and coal are all nonrenewable resources that require mining and removal from under the Earth's surface to use for power and energy. These resources are efficient and useful but come at a cost. This article focuses on the way coal power plants impact the environment. All of the answer choices listed are the adverse effects of the plant. Creating thermal pollution, releasing chemicals into oceans, rivers, and lakes, as well as contaminating the ground and drinking water, are all negative examples of the effect fossil fuels have on the environment.

Coal is used in a variety of ways, and the US is reliant on fossil fuels based on the graph above. Mining fossil fuels has an impact on the environment, and they aren't all positive. If the US population wanted to reduce their coal consumption, the area that would potentially have the most significant impact would be the electricity sector. 54% of US electricity is produced using coal. If the US were able to switch to an alternative energy source, the use of coal could be significantly reduced, which may have a positive impact on the environment.

This article focuses on how coal power plants affect the environment in negative ways. The portion of the environment highlighted in this article are the water sources. The article mentions the warm water being released back into oceans, lakes, or rivers it is pulled from, the potential of chemicals being added back into the bodies of water, and how it can seep into the ground of the water sources.

The statement in the question is false. Fossil fuels are beneficial to humans and fulfill the needs we have for power, electricity, and industrialization, but it comes at a cost to the environment. Mining and stripping the soil, deforestation, water and air pollution, and loss of animal habitats are just a few of the adverse effects that fossil fuels have on the environment.

Based on the graph provided by the US Energy Information Administration, coal is currently on a decline in usage. Following the black line (representing coal), it can be seen that there is a decrease in use. The other energy type is on increasing in usage.

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.

Fossil fuels are used for energy.

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.
