Verified step by step guidance

1. Understand the definition of a nonrenewable resource: it is a natural resource that cannot be replenished or regenerated on a human timescale once it is consumed.
2. Evaluate each option based on whether it can be naturally replenished quickly or not:
3. Timber from managed forests is renewable because forests can regrow over time with proper management.
4. Wind power and solar energy are renewable because they rely on natural processes that are continuously available and do not get depleted by use.
5. Coal is a fossil fuel formed over millions of years and cannot be replenished within a human lifetime, making it a classic example of a nonrenewable resource.
