Rocks & the Rock Cycle

How did the humans use rocks in the past?

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

which of the following does NOT cause magma to form?

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

Sedimentary rock is formed through the process of 

• Cementation
• Stratification
• Erosion
• Foliation

What has to increase for metamorphism to occur? 

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

What is process in which water, wind, and heat break down rock?

• weathering
• exfoliation
• cementation
• composition

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

• coarse grained
• large grained
• medium grained
• fine grained

What are the main categories of sedimentary rock?

• extrusive and intrusive
• clastic, chemical, & organic
• felsic and mafic
• foliated and non-foliated

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

• they stay the same
• they change into coal
• they change into minerals that are less stable
• they change into minerals that are more stable

During the rock cycle, what forms when the magma cools?

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

During the rock cycle, what forms when the magma cools?

• igneous rocks
