Download Metamorphic Rock

“Something about you has
changed.”
Metamorphic means:
“Changed”
 A Metamorphic rock starts out as either Igneous rock,
Sedimentary rock, or another Metamorphic rock.
 But because of great heat and pressure, it is changed
into another type of rock.
Heat and pressure do the work
 When rock is trapped under a lot of other rock it is
under pressure.
 The closer the rock gets to the Earth’s center, the
hotter it gets.
This is what it looks like when rock
gets smashed and heated.
This is what it looks like when Granite (an
Igneous rock) is turned into a metamorphic
rock.
