Answer:
nonrenewable resources
Step-by-step explanation:
There are primarily two types of resources: renewable and non-renewable. The main difference between the two is that the renewable resources can be replenished while the non-renewable resources cannot be replenished.
Examples of non-renewable resources: coal, oil and natural gas. These are called "fossil fuels." Although they only have a limited supply, most of our human activities are dependent on these fossil fuels, which threatens their depletion.
