Foliated

If magma cools above earths surface, what type of rock is formed? (don't forget subtype)

400
___________ igneous rocks forms when ____________ cools underground.
Intrusive, magma
500
How do metamorphic rocks form?
Intense heat and pressure
500
Metamorphic, shiny white inside, and small to medium grained.
Quartzite

Name 1 non-foliated rock.
Rock listed must be metamorphic...
Examples: Quartzite or Marble

What would you expect to be more viscous: lava or magma? Why?
Lava
It is on the surface, so it is cooler and will be more resistant to flow (like cold honey compared to hot honey)
