8th Grade Chapter 4 Assessment

How did humans use rock in the past?

• to play sports
• to write
• to tell time
• to make tools

Which of the following does NOT cause magma to form?

• an increase in the pressure on rock
• a rise in temperature in rock
• a chance in the composition of rock
• a decrease in the pressure on rock

Sedimentary rock is formed through the process of

• stratification
• foliation
• solidification
• ionization

What has to increase for metamorphism to occur?

• weathering and erosion
• temperature and pressure
• melting and cooling
• compaction and cementation

Besides weathering and erosion, what other forces shape Earth's surface features?

• deposition and uplift
• exfoliation and foliation
• melting and temperature
• composition and texture

When magma cools quickly, what kind of texture does rock have?

• course-grained (large mineral crystals)
• medium-grained
• large-grained
• fine grained (microscopic mineral crystals or non at all)

What are the main categories of sedimentary rock?

• extrusive and intrusive
• clastic, chemical, and organic
• felsic and mafic
• foliated and nonfoliated

When temperature and pressure change, what can happen to the minerals in rocks?

• They stay the same
• They fragment and loosen
• They bind closer together
• They change into other minerals

During the rock cycle, what forms when magma cools?

• igneous rock
• sedimentary rock
• metamorphic rock
• foliated rock

What do scientists call the rock that is formed when magma cools?

• igneous rock
• sedimentary rock
• metamorphic rock
• foliated rock
