Metamorphic RockMetamorphic Rockfrom Greek: meta = “change”, morphosis = “form”

heat and pressure deep beneath Earth’s surface can change any rock into metamorphic rock

How Rocks ChangeHow Rocks ChangeCan change appearance, texture,

crystal structure, and mineral contentCollisions between plates can push

rock down toward mantle or pockets of magma can rise

High temperatures change size and shape of grain and extreme pressure squeezes rock so tightly that the mineral grains may line up in flat, parallel layers

Checkpoint 1Checkpoint 1What are two ways that rocks

can be exposed to intense heat sufficient to turn them into metamorphic rocks?

Checkpoint 1Checkpoint 1What are two ways that rocks

can be exposed to intense heat sufficient to turn them into metamorphic rocks?

They can be pushed down toward the mantle through plate tectonics or pockets of magma can rise.

Types of Metamorphic Types of Metamorphic RocksRocksClassified according to

arrangement of grains that make up the rocks

Types:◦Foliated◦Nonfoliated

classified?According to arrangement of

grains

Page 9: Chapter 5: Rocks Section 5: Metamorphic Rocks. Metamorphic Rock from Greek: meta = “change”, morphosis = “form” heat and pressure deep beneath Earth’s.

Foliated RocksFoliated RocksHave their grains arranged in

parallel layers or bandsFolio is Latin for “leaf”May split apart along bandsE.g. slate (from shale), gneiss

(from granite)

Page 10: Chapter 5: Rocks Section 5: Metamorphic Rocks. Metamorphic Rock from Greek: meta = “change”, morphosis = “form” heat and pressure deep beneath Earth’s.

Nonfoliated RocksNonfoliated RocksMineral grains are arranged

randomlyDon’t split into layersE.g. quartzite (from sandstone)

Uses of Metamorphic RockUses of Metamorphic RockCertain metamorphic rocks are

important materials for building and sculpture◦Marble (from limestone)

Fine, even grain – can be cut into thin slabs or carved into many shapes

Easy to polish – buildings and statues◦Slate

Variety of colors Splits easily into flat pieces – flooring,

roofing, outdoor walkways, chalkboards
