Venn Diagram in TABLE FORM
Using the video segment Processes of Metamorphism complete the table.
* In the Regional Metamorphism column you will type in information that is UNIQUE to
Regional Metamorphism.
* In the Contact Metamorphism column you will type in information that is UNIQUE to Contact
Metamorphism.
*In the Similarities column you will write down information that is common between both the
Regional Metamorphism AND Contact Metamorphism.
Regional Metamorphism
SIMILARITIES
Contact Metamorphism
Use your chart to define Regional Metamorphism AND Contact Metamorphism in your own
words.
Regional Metamorphism:
Contact Metamorphism:

Limestone
Sandstone
** Once you complete your virtual lab, a video will start playing. Write down three facts from
the video.

Use your COMPLETED virtual lab AND the video segment to answer the following questions.
1. What does it mean when a rock is foliated?
2. Describe what happens to rocks when they are pushed under Earth’s surface and
become hotter and experience more pressure?
3. What are two sources of the heat and pressure that cause metamorphism?

Prograde Metamorphism vs. Retrograde Metamorphism
With a partner research the meanings of the terms “Prograde Metamorphism” and “Retrograde
Metamorphism”
Explain the differences between the two processes in YOUR OWN WORDS.
Prograde Metamorphism
Retrograde Metamorphism
Metamorphic Rocks/Minerals
Use the following graph to identify at what temperature and pressure different rocks and
minerals are found.
*Keep in mind that different layers of Earth’s crust have different temperatures and pressures,
meaning different rocks and minerals are found in different layers of the Earth.
Rock/Mineral
Eclogite
Granulite
Greenschist
Hornfels
Zeolite
Sanidinite
Blueschist

videos), answer the following questions, IN YOUR OWN WORDS!
1. How are metamorphic rocks formed?
2. What are the two main types of metamorphic rock?
