Contributor: Meghan Vestal. Lesson ID: 11103

The saying, "Solid as a rock," may not mean much when you see how rocks are constantly changing! This is part of the rock cycle — geology's recycling program. Study it here!

  • Can you explain the information displayed?

This lesson is about the rock cycle.

Understanding how rocks are formed and identifying their characteristics is key to understanding the rock cycle.

So begin investigating the rock cycle by reviewing what you know about igneous, sedimentary, and metamorphic rocks.

Examine the characteristics of each rock pictured and determine whether it is igneous, sedimentary, or metamorphic. If you are able, use the characteristics to determine specifically what type of rock it is (marble, granite, shale, etc.).

(If you were not sure or need more information, check out our Additional Resources in the right-hand sidebar.)

The rock cycle is a process that all rocks constantly undergo as they move and transform into different types of rocks and materials. Think of it as rocks being recycled and changed into other materials and rocks.

Look at the diagram from the beginning of this lesson again. The arrows show how temperature, pressure, weathering, and erosion play a role in changing rocks.

  • Why is the rock cycle important?

The rock cycle plays a role in how the earth changes inwardly and outwardly.
