Questions: docs.google.com Last Name * nay What is a renewable resource? * a. A resource that takes millions of years to form b. A resource that can be replaced naturally in a short time c. A resource that cannot be used again d. A resource that is very expensive Which of these is a nonrenewable resource? * a. Wind energy b. Solar power c. Coal d. Trees

The answer to the first question is b: A resource that can be replaced naturally in a short time.

Explanation for each option:

• a. A resource that takes millions of years to form: This describes a nonrenewable resource, such as fossil fuels, which take millions of years to form.
• b. A resource that can be replaced naturally in a short time: This is the correct definition of a renewable resource, as these resources can be replenished naturally at a pace that allows for sustainable extraction and use.
• c. A resource that cannot be used again: This is incorrect because renewable resources can often be used repeatedly, such as solar or wind energy.
• d. A resource that is very expensive: The cost of a resource does not determine whether it is renewable or nonrenewable.

The answer to the second question is c: Coal.

Explanation for each option:

• a. Wind energy: This is a renewable resource because it is naturally replenished and does not deplete over time.
• b. Solar power: This is also a renewable resource, as it is derived from the sun, which is a constant and sustainable energy source.
• c. Coal: This is a nonrenewable resource because it takes millions of years to form and is depleted much faster than it can be naturally replenished.
• d. Trees: While trees can be considered renewable if managed sustainably, they are not inherently nonrenewable like coal.

In summary, renewable resources are those that can be naturally replenished in a short time, such as wind and solar energy, while nonrenewable resources, like coal, take millions of years to form and are not sustainable in the long term.
