1. A renewable resource is a natural resource that can regenerate if it is alive or can be replenished by biochemcial cycles if it is nonliving, theoretically providing an "infinite" amount over time.
2. Examples of renewable resources include water, sunlight, plants, animals, and wind.
3. A nonrenewable resource differs from a renewable resource because it cannot be regenerated or replenished by natural processes; once used up, it is gone forever, whereas renewable resources can naturally renew themselves.
4. Fossil fuels are classified as nonrenewable resources because although they are technically being formed slowly over millions of years, we consume them at a rate far faster than they can be created, making them effectively finite in human timescales.
5. A renewable resource can become nonrenewable if it is used up faster than it can be replenished—for example, cutting down trees faster than they can regrow eliminates the ability for the resource to regenerate, turning it into a nonrenewable resource.
