Which energy resources is nonrenewable?
A. Biomass
B. Water
C. Coal
D. Wind
C. Coal
The nonrenewable energy resource among the options given is C. Coal.
The nonrenewable energy resource among the given options is C. Coal.
To determine whether an energy resource is renewable or nonrenewable, we need to understand the definition and characteristics of each type.
Renewable energy resources are those that can naturally replenish themselves within a relatively short period. This means that they can be used repeatedly and will not run out. Examples of renewable energy resources include solar, wind, hydropower (referred to as water in the question), and biomass (option A).
Nonrenewable energy resources, on the other hand, are finite and cannot be easily replenished within a human lifetime or reasonable time frame. Once these resources are used up, they are gone forever. Examples of nonrenewable energy resources include fossil fuels such as coal, oil, and natural gas.
Given the options provided, biomass (option A), water (option B), and wind (option D) are renewable energy resources. However, coal (option C) is a nonrenewable energy resource because it is formed over millions of years from the remains of plants and other organic matter under high pressure and heat. Once the limited supply of coal is exhausted, it cannot be renewed within a reasonable human time frame.
