This image represents what process
The Rock Cycle
100
What type of igneous rock is formed from magma that cooled UNDERNEATH the earth's surface?
Intrusive igneous rock
100
What are small particles that make up sedimentary rock called?
Sediments
100
What word/words can you use to remember the properties of metamorphic rock? (think of the vocabulary lesson)
Morph (to change)
200
What type of rock forms from magma or lava?
Igneous rock
200
True or False: Igneous rock can only be the color black
False
200
How is the formation of sedimentary rock different from the formation of igneous rock?
Igneous rock is formed when lava or magma cools and becomes solid while sedimentary rock is formed when sediments are cemented or compacted together.
200
What two forces are required to create metamorphic rock?
Heat and pressure
300
What are the 3 major groups of rocks?
Igneous, sedimentary, and metamorphic
300
What word/words can you use to remember the properties of igneous rock? (think of the vocabulary lesson)
Ignite (to start on fire)
300
What is a common feature of sedimentary rock?
Distinct layers of minerals, lots of different colors, large pieces of different rocks stuck together
300
What kinds of rock can become metamorphic rock.
All types of rock
400
How is the rock cycle a form of recycling?
Preexisting rocks face certain conditions (heat pressure, erosion, etc.) that transform them into new rocks over time so that rocks are always being reused and renewed
400
Igneous rock + weathering to form sediments = ?
Sedimentary rock
400
What word/words can you use to remember the properties of sedimentary rock? (think of the vocabulary lesson)
Sedentary (to not move) or sedate (to calm or make unconscious from a drug)

Free points!
Woohoo!!!
500
What is the process by which Igneous rock transforms into sediment and becomes sedimentary rock?
Weathering or erosion breaks igneous rock into smaller sediments and these sediments are cemented together to form sedimentary rock
500
Free points!
YAYYYY!
500
Does sedimentary rock always form layers of sediment?
No (sometimes the sediments are all mixed together)
500
What happens to the minerals in rocks that undergo metamorphism?
The minerals change in structure.
600
True or False: The rock cycle follows a repeating pattern that always stays the same
False
600
What do you call a rock with large and visible crystals? (hint: fine or coarse grained)
Coarse-grained
600
Name the processes by which sediments become sedimentary rocks.
What is deposition, compaction, cementation, lithification?
600
Metamorphic rock is most likely to take how long to form?
Millions of years
