How Do Rocks Undergo Change?
ES0602  Rock Cycle Diagram

  !   Move your cursor over the arrows to see a list of the rock-forming processes involved in forming the three types of rocks.

The animations on the previous page show just one example of a rock moving through the rock cycle. The rock started as an igneous rock. Think about what the path of the example rock would look like in this diagram of the rock cycle.

1. Sketch this diagram on your answer sheet. Go back to step 2, and put the name of each process illustrated in the animation on the appropriate arrow.

Keep in mind that the example on the previous page didn't show all the ways rocks move through the rock cycle. For instance, igneous rocks can become metamorphic rocks without reaching Earth's surface or becoming sedimentary rocks. Another variation from the example is that any type of rock can become a new rock of the same type.

2. Use your own words to describe the sequence of processes that result in igneous rocks. Describe a specific example of a sedimentary rock becoming an igneous rock.

3. Use your own words to describe the sequence of processes that result in sedimentary rocks. Describe a specific example of a sedimentary rock becoming a new type of sedimentary rock.

4. Use your own words to describe the sequence of processes that result in metamorphic rocks. Describe a specific example of a sedimentary rock becoming a metamorphic rock.
