Lesson 20.1: Critical Reading
Name___________________ Class______________ Date________
Read this passage based on the text and answer the questions that follow.
Resource Availability
Many of the resources we depend on are non-renewable. Non-renewable resources vary in their availability. Some
are very abundant, whereas others are very rare. Resources such as gravel and sand are technically non-renewable
but are so abundant that running out is not an issue. Other resources are truly limited in quantity, including many
minerals. When they are gone, they are gone, and something must be found to replace them. Some non-renewable
resources, such as diamonds and rubies, are costly in part because they are very rare.
Besides abundance, the cost of a resource is determined by how easy it is to locate and extract. If a resource is
difficult to find or obtain, it may go unused unless there are no other cheaper alternatives. For example, the oceans
are filled with an abundant supply of water, but removing salt from ocean water (desalination) is very costly, so this
source of water mainly goes unused. However, if the cost of desalination were to decrease, more ocean water would
likely be used.
Politics may also affect resource availability and cost. Nations that have a desired resource in abundance will often
export that resource to other countries. Countries that need the resource must import it from one of the countries
that produces it. This situation is a potential source of political conflict. Oil is a good example of this. Only 11
countries have nearly 80 percent of all of the world’s oil. They are Algeria, Indonesia, Iran, Iraq, Kuwait, Libya,

Nigeria, Qatar, Saudi Arabia, the United Arab Emirates, and Venezuela. However, the biggest users of oil are the
United States, China, and Japan. This leads to a situation in which the availability and price of oil is determined
largely by oil-producing countries, which have their own interests to look out for. They may raise the price of oil for
reasons that have nothing to do with the cost of obtaining it. Wars may even be fought over oil or other resources
that are not evenly distributed.
Questions
1. Describe variability in the abundance of non-renewable resources.
2. Besides abundance, what factors determine the cost of natural resources?
3. Which countries have the most oil reserves, and which countries use the most oil? Why is this situation a
potential source of political conflict?

Lesson 20.1: Critical Writing
Name___________________ Class______________ Date________
Thoroughly answer the question below. Use appropriate academic vocabulary and clear and complete sentences.
For many natural resources, the categories of renewable and non-renewable are not completely separate. Instead,
they are more like two ends of a continuum. Explain why, and illustrate your answer with examples.
