One Rock to Another
Lesson #47
Crust (thin outer shell of
solid rock plates)
Lithosphere
(outer zone of Earth made of
crust and the outermost part
of the mantle)
Mantle
(hot molten rock called magma)
Outer Core
(molten iron and nickel)
Inner Core
(solid iron and nickel)

Metamorphic Rock
Lesson #48
Quick Write: Metamorphic rocks change form one type to
another and source rocks become morph rocks! Infer the
source rock that may produce each of these morph rocks.

Today’s Plan:
-Metamorphic Rock Formation
-Project presentation details
-New Jobs
-Reading
Reminders:
Project due 11-25
Period 1: Bonus 5 points if you
are ready on Monday 11-24
Igneous rock: Formed when magma from the Earth’s mantle cools and
crystallizes!
Intrusive and Extrusive Igneous Rock
Magma can solidify in two ways:
• Intrusive Igneous Rock: Solidifies below the surface of the
earth, in the crust.
– Examples: granite
• Extrusive Igneous Rock: Solidifies on the surface of the
land. (When lava spills onto land through a volcano!)
– Examples: obsidian, pumice,
tuff, scoria, basalt

Lesson #48
Metamorphic Rocks
• Metamorphic means “changed”
• Metamorphic rocks change form one type to
another!

Metamorphic Rock
Lesson #48
Metamorphic Rocks
Change is brought about by heat and/or pressure.
• Pressure results when rocks are buried deep in the
ground or magma pushes up from below.
• Heat results when rocks are covered in lava.
• Metamorphic rocks never completely melt.

Metamorphic Rock
Lesson #48
Metamorphic Rocks
– Source Rock: The original rock that changes into
the metamorphic rock.
– Morph Rock: The metamorphic rock the source
rock changes into.

Project Presentations
 About 3 minutes to summarize your work.
 Do not read directly from your board or
PowerPoint
 Make good use of your visuals (point to
specifics as you explain)
 Stay positive, enthusiastic, and confident!
 Look at your audience and don’t mumble.
Presentation Outline
~Introduce the focus question
~State your hypothesis (What you thought the answer
would be before you started)
~Your research process– how you obtained the
information and any difficulties
~Your findings – What you found out, explanation of
diagrams or models, was the hypothesis correct, how
the work addresses your focus question, and were you
able to answer the question?
~Professional level – Share your teaching point with the
group. How will you know they understood (Exit slip?
Feedback questions?)
~What are the most important things you learned?
New Jobs!
