Answer:
The difference between a renewable and a non-renewable natural resource is whether or not the resource can be replaced.
Explanation:
Natural resources are those useful for human beings and for that reason are consumed by them.
Renewable natural resources —such as water, plants and trees or solar energy— are usually renewed at a rate greater than or equal to their consumption, so they are not depleted.
A non-renewable natural resource, such as petroleum, usually has a limited existence, or its renewal speed is very slow, so its consumption can decrease its quantity or deplete it.
The difference between renewable and non-renewable resources is in their long-term availability or depletion.
Other options are not correct because:
- <em>Both types of resources exist in nature.
</em>
- <em>Both resources can decrease, but one is renewable and the other can be depleted.
</em>
- <em>Both renewable and non-renewable resources are useful for humans.</em>
