Rocks and rock cycle

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

• metamorphic rock

• extrusive rock

• sedimentary rock

• igneous rock

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

• chemical rock

• extrusive rock

• foliated rock

• intrusive rock

A sedimentary rock formed from pieces of other rocks is called a(n)

• organic rock

• chemical rock

• clastic rock

• compacted rock

A deposit of organic limestone on land probably formed millions of years ago as a(n)

• extrusive rock

• coral reef

• chemical rock

• metamorphic rock

A metamorphic rock in which the grains line up in parallel bands is a

• clastic rock

• nonclastic rock

• nonfoliated rock

• foliated rock

In the rock cycle, the process by which an igneous rock changes to a sedimentary rock must begin with

• cementation

• deposition

• erosion

• compaction

Relationship between an igneous rock's texture and where it is formed is..

• a rock that cooled slowly underground would be pumice

• rock that cooled slowly underground produced small crystals

• rock that cooled quickly on surface, produced small crystals

• rock that cooled quickly on surface, produced large crystals

water can pass easily through sandstone and not shale because....

• more space between the grains of the sandstone

• more space between the grains of shale

what type of rock is formed by evaporation?

• coal

• shale

• halite (rock salt)

• gneiss

What 2 forces cause metamorphic rock to form?

• weathering and erosion

• sediment and deposition

• melting and erosion

• heat and pressure
