THE ROCK CYCLE

The series of processes that change one type of rock into another type of rock is called the ________________________

Rock Cycle Diagram
1. Use the following five processes to label every arrow on the rock cycle diagram: compaction and cementation,
melting, cooling and hardening, heat and pressure, weathering and erosion.
Sediments
Igneous Rock
Magma
Sedimentary Rock
Metamorphic Rock
Starburst Lab: Conclusions and Analysis Questions
1.
We already know that we could turn the sedimentary rock into metamorphic rock (we did that in step #3). How could you
turn the sedimentary rock into igneous rock without going through the metamorphic stage?
2.
You are probably starting to see that any form of rock can be changed into any other form of rock. How could a rock be
changed but still be classified as the same form of rock?
3.
What type of rock do you think forms from erupting volcanoes?
4.
Which rock is formed from broken-down pieces of rock? How do you think these pieces harden into rocks in nature?
5.
How can this activity be described as a cycle?
6.
Besides using Starbursts to represent minerals, how is this model of the rock cycle different than the real rock cycle in
nature? (Hint: Think heat and pressure)
