Fossil fuel.
No, coal is a finite resource that is formed over millions of years from decaying plant matter. As it is mined and burned for energy, its reserves are gradually depleted. Additionally, burning coal contributes to air pollution and greenhouse gas emissions, making it an unsustainable energy source in the long term.
The term that describes energy stored inside the nucleus of an atom is nuclear energy. It is released through processes such as nuclear fission and fusion.
Coal is considered a scarce resource because its formation takes millions of years and the rate at which it is being consumed far exceeds the rate at which it is being naturally replenished. Furthermore, the extraction of coal can be environmentally damaging, leading to concerns about its long-term sustainability as an energy source.
Freezing describes the process of a liquid turning into a solid as it loses heat energy.
Activation energy is the term used to describe the energy required to start a chemical reaction by breaking the initial bonds between atoms or molecules. This energy barrier must be overcome in order for the reaction to proceed.
renewable
The term for a fuel that contains an energy source which has not been converted is "primary fuel." This refers to natural resources like coal, oil, or sunlight that can be used directly without further processing.
The term clean source of energy refers to only primary energy sources as wind or solar energy. Electricity, by definition, is not a primary energy source. It is a secondary energy source that is could be produced by a clean energy source as wind or any renewable primary energy source or produced by fossil energy source as oil, natural gas, or coal.
The term is "trophic level" and it describes an organism's position in a food chain or food web based on its energy source and how it obtains energy.
The term that describes the amount of energy available to heat the Earth's land, water, and air is "solar radiation." Solar radiation, or sunlight, is the primary source of energy that heats the Earth's surface and drives weather and climate systems.
Stored energy
Solar energy.
No, coal is a finite resource that is formed over millions of years from decaying plant matter. As it is mined and burned for energy, its reserves are gradually depleted. Additionally, burning coal contributes to air pollution and greenhouse gas emissions, making it an unsustainable energy source in the long term.
nonrenewable energy
Nuclear energy can be considered one of the worst sources of energy due to the potential for catastrophic accidents, long-term environmental impact from radioactive waste, and concerns about nuclear proliferation.
