Metamorphic Rocks
Can metamorphic rocks be non-foliated?
Yes
What are sedimentary rocks made of?
Igneous rocks form from...
magma/lava
What happens to an igneous rock on a sunny day?
Nothing. The rock stays the same.
How do you test the streak of a rock or mineral?
Use a streak plate and scratch the rock or mineral against it
(Texture) Extreme pressure may lead to...
Foliation
How do sedimentary rocks form?
sediments are squeezed together by the weight of overlying sediments (compaction)
fluids fill in the spaces (cementation)

What does metamorphic rock turn into after melting?
Magma
Fracture is...
the pattern in which a mineral breaks

What is contact metamorphism?
came into contact with magma = extreme heat
