Rocks
There are three different types of rocks. Variations in rocks occur because of the rock cycle. Figure 1 contains
a diagram of the rock cycle. Use Figure 1 to answer the following questions.

8 . Suppose Earth’s atmosphere gets warmer. As a result, the ocean level rises and precipitation increases around
the world. Discuss the effects, if any, of these changes on the rock cycle. What types of rocks would you
expect to find 1000 years after the changes began? Why would these rocks predominate?
