Minerals & Classifying Rocks/Rock Cycle Retest

If you have any additional questions about the test, please see your teacher so they can go over it before you start the retest. Do you have any questions?

The diagram is a model of the rock cycle. Which of these BEST explains a problem using this type of model for the rock cycle?

• It does not show how fast rocks can change.

• It does not show the three major rock types.

• It does not show that rocks can melt.

• It does not show that weathering changes rock.

When a sedimentary rock changes shape under heat and pressure, but does not melt completely, it becomes which of the following types of rock?

• igneous

• magma

• metamorphic

• volcanic

Limestone, a sedimentary rock, can be found in the bedrock of some inland states in our country that scientists believe were once covered by an ocean. Which of these BEST explains the relationship between oceans and limestone formation?

• Magma erupts into ocean floors and is hardened by water into limestone.

• Organic matter settles and accumulates on the bottom of the ocean to limestone.

• Water erodes the bedrock at the bottom of the ocean and reduces it to limestone.

• Ocean mass bears down heavily on igneous rock and compresses it into limestone.

Rocks that are located deep within the Earth's crust would be identified as --

• layered

• metamorphic

• sedimentary

• thermic
