Unit 8 Rock

A student makes a cross-section clay model to represent the internal structure of a volcano that leads to the formation of two rocks (X and Y). The student records the processes that affect the type of rock that is formed in a table.

The image shows the rock cycle and the associated process leading to the formation of 2 kinds of rocks labeled rock 1 and rock 2.

What are the types of rocks formed?

• Rock 1 is intrusive igneous, rock 2 is an extrusive sedimentary.

• Rock 1 is extrusive igneous, rock 2 is an intrusive sedimentary.

• Rock 1 is intrusive sedimentary, rock 2 is an extrusive sedimentary.

• Rock 1 is intrusive igneous, rock 2 is an extrusive igneous.

Which section of rock is made of minteral crystals that cooled from magma?

• A

• B

• C

• D

Which rock was formed from exposure to extreme heat and pressure?

• A

• B

• C

• D

Rock type K was formed by deposition and cementation of weathered minerals. This rock then experienced significant heat and pressure to form rock type L, which subsequently melted and cooled slowly to form rock type M.

What is the identity of rock type M?

• extrusive igneous

• intrusive igneous

• metamorphic

• sedimentary

A student lists three processes that occur to a rock.

Assuming the rock finishes a fourth process of melting and slow cooling, what are the classifications of the rock after the first and fourth processes?

• 1: metamorphic; 4: sedimentary

• 1: metamorphic; 4: intrusive igneous

• 1: intrusive igneous; 4: sedimentary

• 1: intrusive igneous; 4: metamorphic

• 1,2,4,3

• 3,4,2,1

• 4,3,2,1

A student examines a cross section of an area with a rock layer labeled X.

Which is the best description of rock layer X?

• It is an igneous rock layer that is older than the sedimentary rock around it.

• It is an igneous rock layer that is younger than the sedimentary rock around it.

• It is a sedimentary rock layer that is older than the igneous rock around it.

• It is a sedimentary rock layer that is younger than the igneous rock around it.
