• Rock 
• Composition
• Texture

• Rock
• Compostion
• Texture

Rock that cools slowly beneath the earths surface. Large, visible crystals.

• Intrusive
• Extrusive 
• Foliated
• Nonfoliated

Rock that cools quickly at the earths surface. Small fine-grained crystals.

• Intrusive
• Extrusive
• Foliated
• Nonfoliated

Pressure and specific temperatures in the rock causes the mineral grains to realign and form parallel bands.

• Intrusive
• Extrusive
• Foliated
• Nonfoliated

Pressure and heat form rocks that are not in planes or bands. Usually made primarily of quartzite and marble.

• Intrusive
• Extrusive
• Foliated
• Nonfoliated

Formed when sediments are buried, compacted, and cemented together with calcite or quartz.

• Clastic
• Chemical
• Organic

Formed when water evaporates and minerals precipitate and form crystals.

• Chemical
• Organic

Formed from the remains of once living plants and animals. Fossils.
