Rocks can be classified as sedimentary, igneous, and metamorphic. Each type of rock is a different part of the rock cycle, and is formed in different ways. In this activity, students will create a chart that illustrates the different types of rocks. In addition to providing examples, encourage students to write a description of the rock and how it is formed. As an extended activity, have students examine the differences between intrusive and extrusive rocks.
