An Igneous rock deep within the Earth experiences extreme temperature and pressure. After a long period of time it becomes which rock?

• Magma

• Igneous

• Metamorphic

• Sedimentary

What are the 3 major types of rocks?

• Igneous, Metamorphic, Sedimentary
• Metamorphic, Igneous, Cementation
• Brown, Red, Gray
• Streak, Hardness, Breakage

The process in which sediment are fused or glued together.

• Melting

• Friction

• organic rock
• cementation

True or False: Once a rock is sedimentary, it cannot become an igneous rock.

• True
• False

A never ending process by which rocks are changed from one type to another.  

• weathering and erosion
• rock cycle
• heat and pressure
• pressing and cementing

What process is used to form sedimentary rocks?

• Lava cools and hardens to form a rock.
• Bits of sand and gravel form layers that turn into rock from pressure.
• Extreme heat and pressure from inside the Earth turn rocks into new rocks.
• Magma trapped under the Earth's surface cools and solidifies.

This type of rock is formed when you cool melted rock.

• Sedimentary
• Igneous
• Metamorphic
• Lava Rock

You can see layers in this rock.  Could be sand, or pebbles.

• Sedimentary
• Igneous
• Metamorphic
• Sand Rock

Which force plays a major role in the formation of metamorphic rock?

• Acceleration

• Friction

• Pressure

• Centrifugal force

Sedimentary rock forms

• When meteors fall to the earth.
• When magma cools.
  
• In layers.
• In the core of the earth.
