About Rocks
The Rock Cycle
Sedimentary Rocks
Igneous Rocks
Metamorphic Rock
100
These are four of the most common rock forming minerals.
What are Quartz, Feldspar, Hornblende, Mica?
100
This process occurs when layers of sediment compress together to form a rock
What is compaction?
100
Sediments can be different things. Name three things that sediments can be.
What are rock fragments, mineral grains, plant and animal remains?
100
True or False: Igneous rocks are the most abundant types of rocks on earth.
What is true?
100
Metamorphic rocks undergo changes because of increases in these two things....
What are pressure and temperature?
200
When rocks form, they are a mixture of these four things.
What are minerals, mineraloids, glass or organic matter?
200
This process occurs when large sediments are glued together by minerals deposited between the sediments.
What is cementation?
200
Sediments can be different sizes. List the different sediment sizes in order from smallest to largest.
What are clay, silt, sand, gravel?
200
Igneous rocks are formed when this cools.
What is magma/lava or molten material?
200
Metamorphic rocks that have mineral grains that flatten and line up in parallel bands are called this....
What are foliated metamorphic rocks?
300
These are the three main types of rocks.
What are metamorphic, sedimentary, igneous?
300
If an igneous rock is subjected to immense amounts of heat and pressure over long periods of time, it will become this type of rock.
What is metamorphic?
300
There are three types of sedimentary rock--name them.
What are detrital, chemical and organic?
300
Gabbro, diorite and granite are examples of this type of igneous rock.
What are intrusive igneous rocks?
300
These are two examples of foliated metamorphic rock...
What are slate and gneiss?
400
This occurs when rocks break into smaller pieces either chemically or mechanically.
What is weathering?
400
If a metamorphic rock melts and becomes magma and then cools again, it will become this type of rock.
What is igneous?
400
Detrital sedimentary rocks have this kind of texture--it means rough and coarse.
What is clastic texture?
400
Because they cool slowly, intrusive igneous rocks have this type of mineral grains.
What is large mineral grains?
400
Non-foliated metamorphic rock have mineral grains that do this....
What is rearrange but do not show banding?
500
This process occurs when weathered rock moves to another location (usually by wind, water, glaciers or gravity)
What is erosion?
500
If an igneous rock is weathered and eroded to become sediments and then is compacted and cemented together over time it will become this type of rock.
What is sedimentary?
500
This type of sedimentary rock is made from the remains of once living organisms---an example is coal.
What is an organic sedimentary rock?
500
Igneous rocks that form at or above the earth's surface are called this type of igneous rock.
What are extrusive igneous rocks?
500
THese are two examples of foliated metamorphic rock.
What are quartzite and marble?
