1. Plastics are made from petroleum. Because of plastic's flexibility and sturdiness, people use plastics to make many different kinds of products. How does the increase in the use of plastics affect the availability of petroleum?

Correct Answer: Correct answer is: (A) It decreases petroleum's availability.

Exam Relevance: AP Environmental Science, GRE, MCAT

Difficulty: Moderate

Concept notes: Petroleum is a finite natural resource used in the production of plastics. As the use of plastics increases, more petroleum is required to meet the demand, leading to a decrease in the availability of petroleum.

Common Mistakes: A common misunderstanding is that the production of plastics might somehow increase the availability of petroleum, which is incorrect because petroleum is a non-renewable resource.

Explanations: Petroleum is a non-renewable resource, meaning it cannot be replenished on a human timescale. As the demand for plastics increases, more petroleum is extracted and used in the manufacturing process. This extraction and use directly reduce the amount of petroleum available for future use, leading to a decrease in its overall availability.

Option Analysis:

Option A: This is the correct answer because the increased use of plastics leads to higher demand for petroleum, which decreases its availability.
Option B: This is incorrect because the erratic availability of petroleum is not a direct result of increased plastic use; it is a finite resource that decreases with use.
Option C: This is incorrect because the increased use of plastics does affect petroleum availability by reducing the amount of petroleum left.
Option D: This is incorrect because the increased use of plastics does not increase the availability of petroleum; it decreases it.

2. How long will natural resources be around?

Correct Answer: Correct answer is: (B) Natural resources will eventually run out if used faster than they form.

Exam Relevance: AP Environmental Science, GRE, MCAT, GMAT

Difficulty: Moderate

Concept notes: Natural resources are materials or substances that occur naturally and can be used for economic gain. These resources can be categorized into renewable and nonrenewable resources. Renewable resources can be replenished naturally within a human timescale, while nonrenewable resources take millions of years to form and cannot be replenished once depleted.

Common Mistakes: A common misunderstanding is that all natural resources are infinite or can be easily replenished, which is not true for nonrenewable resources.

Explanations: Nonrenewable resources, such as fossil fuels and minerals, are finite and will eventually run out if consumed faster than they can be formed. This is why it is crucial to manage and conserve these resources sustainably. Renewable resources, while replenishable, can also be depleted if used at a rate faster than their natural replenishment rate.
