Resource that exists in a fixed amount (stock) in various places in the earths crust and has the potential for renewal by geological, physical, and chemical processes taking place over hundreds of millions to billions of years. Examples are copper, aluminum, coal, and oil. We classify these resources as exhaustible because we are extracting and using them at a much faster rate than they were formed.

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Resource that exists in a fixed amount (stock) in various places in the earth’s crust and has the potential for renewal by geological, physical, and chemical processes taking place over hundreds of millions to billions of years. Examples are copper, aluminum, coal, and oil. We classify these resources as exhaustible because we are extracting and using them at a much faster rate than they were formed.

A	nonrenewable resource
B	renewable resource
C	solar energy
D	perpetual source

Explanation:

Detailed explanation-1: -Nonrenewable Resources This means that they exist in a fixed amount on Earth. Rock, minerals, metals, uranium, and fossil fuels such as petroleum, coal, and natural gas are all nonrenewable resources.

Detailed explanation-2: -There are four major types of nonrenewable resources: oil, natural gas, coal, and nuclear energy. Oil, natural gas, and coal are collectively called fossil fuels. Fossil fuels were formed within the Earth from dead plants and animals over millions of years-hence the name “fossil” fuels.

Detailed explanation-3: -Nonrenewable resources are natural resources that exist in fixed amounts and can be used up. Examples include fossil fuels such as petroleum, coal, and natural gas.

Detailed explanation-4: -Renewable resources include biomass energy (such as ethanol), hydropower, geothermal power, wind energy, and solar energy. Biomass refers to organic material from plants or animals. This includes wood, sewage, and ethanol (which comes from corn or other plants).
