Metamorphic Rock

Any rock formed when another rock is changed by heat or __________ is a metamorphic rock.

• pressure
• arrangement

Metamorphic rock can form out of other metamorphic rock.

• true
• false

Geologists classify metamorphic rocks according to the __________ of the grains making up the rocks.

• pressure
• arrangement

The deeper a rock is buried in the crust, the greater the pressure on that rock.

• true
• false

How do metamorphic rocks form? 

• Heat and Pressure
• Compaction & Cementation
• Cooling of Magma
• Sediments & Glue

What do we call the group of metamorphic rocks that have visible layers or bands of minerals within them?

• Sedimentary
• Stratified
• Foliated
• Unfoliated

How is a sedimentary rock made?

• By intense heat and/or pressure
• By compacting and cementing
• Cooling and solidification of lava or magma

How is a igneous rock made?

• By intense heat and/or pressure
• By compacting and cementing
• Cooling and solidification of lava or magma

What are the two main types of metamorphic rocks and how are they different?

• intrusive and extrusive; intrusive rocks are formed inside the earth and extrusive rocks are formed on the surface
• foliated and nonfoliated; foliated rocks do not have visible bands/layers and nonfoliated rocks do have visible bands/layers
• intrusive and extrusive; intrusive rocks are formed on the earth's surface and extrusive rocks are formed in the Earth
• foliated and nonfoliated; foliated rocks have visible bands/layers and nonfoliated rocks do not have visible bands/layers

When metamorphic rocks are formed, the extreme heat is usually caused by the _______.

• gravity in the atmosphere
• collision of tectonic plates
• the fiery hot magma in the Earth's mantle
• weight of the mountains
