Earth Science Rock Cycle

The rock shown is composed primarily of large crystals that were formed by —

• cooling magma

• compacting shells

• weathering

• faulting

When granite is subjected to high enough amounts of heat and pressure to change it but not melt it, granite changes into —

• a metamorphic rock

• an igneous rock

• sediments

• a sedimentary rock

Of these igneous rocks, which would contain the largest crystals?

• Granite

• Obsidian

• Pumice

• Rhyolite

The two types of metamorphic rock are

• clastic & nonclastic

• extrusive & intrusive

• clastic & recrystalized

• foliated & nonfoliated

Which of these best describes intrusive igneous rock?

• solidifies from lava, cools quickly, large crystals

• solidifies from lava, cools slowly, small crystals

• solidifies from magma, cools quickly, large crystals

• solidifies from magma, cools slowly, large crystals

Pumice is an igneous rock that can float on water. Which of these is most likely pumice?

• A

• B

• C

• D

Metamorphic rocks that have a banded or layered appearance are called

• nonfoliated

• foliated

• clastic

• organic

ROCK is made of ________.

• water

• minerals

• air
