To survive and advance, humans have used the natural resources in their environment for at least as long as recorded history.

Some of these are renewable, like the wood from a forest, and some natural resources are not renewable, like oil pumped out of the ground. This is because we can use the wood from the forest, and plant trees to replace what was taken. With oil, we cannot replace what we have used, so when it is gone, it is gone for good.

What is another example of a resource that has a limited supply?

A)
air

B)
soil

C)
coal

D)
sunlight

I think coal

Yes, definitely. It's coal.

thanks

You're welcome.

The correct answer is C) coal. Coal is a fossil fuel that takes millions of years to form from prehistoric vegetation. Once we extract and burn coal for energy, it cannot be replenished on a human time scale. Therefore, coal is considered a non-renewable resource with a limited supply.

To determine the correct answer, we can work through the options:

A) Air: Air is a mixture of gases like nitrogen, oxygen, and carbon dioxide, which are essential for life. Although air quality can be affected by pollution, the supply of air itself is not limited.

B) Soil: Soil is a vital natural resource for agriculture and plant growth. While soil degradation can occur due to erosion or poor management practices, soil itself is a renewable resource. With proper care, soil can be replenished and restored through natural processes.

C) Coal: As mentioned earlier, coal is a non-renewable resource that takes millions of years to form. Once mined and burned for energy, it cannot be replaced within a human timescale.

D) Sunlight: Sunlight is not a tangible resource like the others mentioned. It is a form of energy that is constantly produced by the Sun. While the amount of sunlight reaching Earth may vary based on factors like cloud cover or seasons, sunlight itself is not limited.

Therefore, the answer is C) coal as it is a resource that has a limited supply.
