Lesson 2: what is the rock cycle?

2. Rock Cycle: The sequence of processes that change rocks from one type to another over long periods.

3. There are no first or last steps in the rock cycle because it’s a never ending cycle. Any step can follow any other step.

4. Metamorphic rock to igneous rock
What steps can turn metamorphic rock into igneous rock?
Step 1
Metamorphic rock is exposed to heat, and it melts. It becomes magma (or lava)
Step 2
Magma cools and becomes igneous rock

5. Sedimentary rock into metamorphic rock
What steps can turn sedimentary rock into metamorphic rock?
Step 1
Sedimentary rock is exposed to heat or pressure.
Step 2
The sedimentary rock changes into metamorphic rock.

6. 5. What type of rock forms when high heat or great pressure act on sandstone?
-Quartzite forms

7. 6. What new type of rock can form after quartzite melts?
-the igneous rock andesite
7. Lava, sediment and sand are all produced by the rock cycle.
