Final answer:
A natural material that can be replenished quickly by natural processes as quickly as it is used by humans is known as a renewable resource. Sunlight and wind are typical examples. In contrast, nonrenewable resources, like fossil fuels, cannot be replenished fast enough and are in limited supply.
Step-by-step explanation:
A natural material that can be replaced relatively quickly by natural processes is known as a renewable resource. These are resources that can be replenished by natural processes at a rate comparable to their consumption by humans. Examples include sunlight, wind, hydropower, and geothermal power. Unlike nonrenewable resources, such as coal and other fossil fuels, which exist in fixed amounts and are depleted much faster than nature can replace them, renewable resources are not in danger of being used up.
Furthermore, materials like wood and bamboo, when used sustainably, can also be considered renewable because they are biodegradable and can be regrown through proper forestry management.
In contrast, nonrenewable resources, such as minerals and fossil fuels, take millions of years to form and therefore cannot be replenished at a pace that meets human consumption.
