U2 P2 Review: The Rock Cycle

Rocks can be classified as igneous, metamorphic, and sedimentary. This classification is based on the 

• way rocks form. 

• use of the rocks. 

• size of the rocks. 

• hardness of the rocks.

What determines the texture (crystal size) of an igneous rock?

• the type of magma

• rate of cooling

• type of minerals

• types of sediments

When the mineral crystals in an igneous rock are large and easy to see, the rock is described as 

• extrusive.

• fine grained.

• intrusive.

• nonbanded.

To describe a rock’s texture, geologists determine

• the size, shape and pattern of the rock’s grains.

• how the rock formed.

• the color and density of the rock.

• how many minerals the rock contains.

  Rock that forms from the cooling of magma or lava is called a(n)

• sedimentary rock.

• metamorphic rock.

• igneous rock.

• chemical rock.

 An igneous rock containing small or no crystals is most likely a(n)

• Chemical rock

• Foliated rock

• Extrusive rock

• Intrusive rock

An intrusive igneous rock

• lacks crystal structure.

• formed from lava that erupted onto the surface.

• formed from magma below Earth’s surface.

• is fine-grained with small crystals.

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

• Metamorphic rock.

• Extrusive rock.

• Sedimentary rock.

• Igneous rock.
