Rocks

A rock formed from fragments of other rocks is a(n)

• Metamorphic Rock
• Sedimentary Rock
• Extrusive Rock
• Igneous Rock

An igneous rock containing large crystals is most likely a(n)

• Chemical Rock
• Foliated Rock
• Extrusive Rock
• Intrusive Rock

You find a rock in which the grains are arranged in parallel bands of white and black crystals.  The rock is probably a(n)

• Igneous rock
• Sedimentary rock
• Metamorphic rock
• Extrusive rock

The three groups of rocks are classified by

• How they form
• Color
• Grain size
• Chemical Composition

Fossils are only found in

• Sedimentary rocks
• Foliated Metamorphic rocks
• Igneous Rocks
• Nonfoliated Metamorphic rocks

What two processes form sedimentary rocks?

• compaction and cementation

• heat and pressure

• compaction and pressure

• cooling magma

Erosion, wind, and weathering form this type of rock.

• sedimentary

• igneous

• metamorphic

As rock gets buried through tectonic movement, the pressure and heat causes these types of rocks to form.

• sedimentary

• igneous

• metamorphic

Igneous rock is formed when

• magma cools

• erosion layers rock

• Rock composition changes do to plate burial
