What IS your metabolism?

Your metabolism changes _______ to _________.

metamorphic rock1
Metamorphic Rock
  • Meaning to change shape
  • Changes with temperature
  • and pressure, but remains
  • solid
  • Usually takes place deep in
  • the Earth

metamorphic rocks
Metamorphic Rocks
  • Regional Metamorphism – pressure builds up in rocks that is deep within the Earth
  • Large pieces of the Earth’s crust collide and the rock is deformed and chemically changed by heat and pressure

metamorphic rocks1
Metamorphic Rocks

Hornfels is a fine-grained non-foliated metamorphic rock produced by contact metamorphism

Contact Metamorphism – heated by nearby magma

Increased temperature changes the composition of the rock, minerals are changed into new minerals

Metamorphic Rock

Marble is a non-foliated metamorphic rock that is produced from the metamorphism of limestone.

It is composed primarily of calcium carbonate.

Non-Foliated – mineral grains are not arranged in plains or bands
