Final answer:
Air, water, trees, rocks and minerals, coal, and oil are examples of natural resources. These can be further categorized as renewable (like air, water, and trees) and nonrenewable (like coal, and oil).
Step-by-step explanation:
Air, water, tree, rocks and minerals, coal, oil are examples of natural resources. Natural resources are materials or substances that occur in nature and can be used for economic gain. They are classified into two main types: renewable resources and nonrenewable resources.
Renewable resources are those that can be replenished naturally at the same rate as they are consumed. Examples of renewable resources include solar energy, wind, and trees. Conversely, nonrenewable resources are those that do not replenish at a sufficient rate to keep up with consumption. These include coal and oil, which are fossil fuels that took millions of years to form and are used up far more quickly than they are replenished.
Understanding the balance between renewable and nonrenewable resources is crucial for sustainable development. The items listed span both categories: air, water, and trees are renewable, while rocks and minerals, coal, and oil are nonrenewable. Therefore, these examples collectively fall under the broader category of natural resources (Option C).
