Which term describes resources derived from inexhaustible sources such as the sun and wind?

• A. Renewable
• B. Flow or perpetual
• C. Perpetual natural resources
• D. Nonrenewable

Answer: (B)

Resources that come from inexhaustible inputs like the sun and wind are described as flow or perpetual resources. These are supplies that stay available continuously and aren’t depleted by use on a human timescale because the sources themselves are ongoing. Renewable is a broader category that includes things that replenish, but the idea here is inexhaustibility on practical terms, which is captured most precisely by flow or perpetual resources. Nonrenewable describes finite resources that can eventually run out. Perpetual natural resources is another way to say the same idea, but flow or perpetual is the standard label used in this context.
