Rock Cycle:
Melting & cooling
If a statement is true according to the diagram, circle the check box. If not, rewrite it below to make it true.
Only sedimentary rock gets weathered and eroded
FALSE. All rocks can be weathered and eroded.
Sedimentary rocks are made from rock fragments from all three rock types and minerals.
TRUE
Heat and pressure create igneous rocks
FALSE. Melting rock to magma and cooling magma then make igneous rocks.
Metamorphic rocks are created by melting and cooling.
FALSE. Heat and Pressure make metamorphic rock.
Uplift only happens when metamorphic rocks weather and erode.
FALSE. Not just metamorphic, ALL rocks.
A metamorphic rock can’t become igneous without melting first
TRUE
After weathering and erosion, rock has to go through deposition, compaction and cementation
to become sedimentary.
TRUE
Metamorphic, igneous, and/or sedimentary rocks can undergo heat and pressure and become
metamorphic.
TRUE
If a rock exists at the surface of Earth, the next step it must go through in its cycle is weathering.
TRUE
In one sentence, write a brief summary of the rock cycle:
The rock cycle is the process that all rocks go through to change from one type of rock into another type of rock.
The cycle goes on forever and ever, it never ends. It explains how metamorphic, igneous and sedimentary rocks
can change into each other.
Metamorphic Rock:
Circle the non-foliated metamorphic rock. Put a box around the foliated.
Complete the table below, by putting the type of rock (igneous, sedimentary, metamorphic) being described in
the first column. Use the clues given in the other columns.

What do we call a layered or banded texture formed when minerals realign in metamorphic rock?
________Foliated_____________________________________________________________________
List the parent rock of each of the following metamorphic rocks:
gneiss ___Granite__________________________ marble _________Limestone_____________________
slate ________Shale_______________________ quartzite ______sandstone_______________________
Where does metamorphism take place? Why? ______Deep underground because it needs a lot of heat and a
lot of pressure._____________________________________________
What is the meaning of the word metamorphic? ____to change_____________________________________
