Which term describes resources that come from limitless sources such as the sun, the atmosphere, and large ocean bodies or flowing water riverine systems?

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

Answer: (B)

Resources that come from sources that never run out on human time scales are described as flow or perpetual resources. These are energy sources that continually supply energy as natural processes occur—sunlight, wind, ocean currents, and the movement of water in rivers. The key idea is that the source keeps replenishing itself, so using the resource doesn’t deplete it in the way fossil fuels or minerals do. Flow or perpetual resources differ from nonrenewable resources, which form too slowly to replace what we use, and from other renewables that still require careful management to avoid local depletion. So, the term that best fits these limitless-sourced resources is flow or perpetual resources.
