Non-Foliated Rocks
Marble QuartzNo Stripes Here!
Parent Rocks
The rock that the metamorphic rock comes from.
Can you pair up the parent & metamorphic rocks?
Uses of Metamorphic RockMarble
beautiful & durable
statues & buildings (like the Taj Majal!)
Uses of Metamorphic RockSlate
foliated & able to break into thin sheets
roof tiles, chalkboards, floor tile
Uses of Metamorphic RockSchist
break it down for its minerals
talc - cosmetics, powder, lubrication
graphite - pencil “lead”, lubrication
Bellwork
Molten (melted) rock can be found above and below Earth’s surface. What is it called in each of these places? How do the rocks that form above and below ground differ?
Use the textbook p. D40-D45 if necessary.
