Rock Cycle, What?
Igneous
Sedimentary
Metamorphic
Just Because
100
A natural, solid mixture of minerals or grains...
What is a rock?
100
Igneous rocks form from...
What is the cooling and crystallization of molten rock above or below Earth's surface?
100
This type of sedimentary rock has broken pieces of minerals and rock fragments.
What are clastic rocks?
100
Process that affects the structure or composition of a rock in a solid state because of increased pressure and temperature.
What is metamorphism?
100
Andesite is an example of this type of rock (be specific!)
What is extrusive, igneous?
200
The fragments that make up a rock are called these...
What is a grain?
200
Volcanic material that erupts and cools and crystallizes on Earth's surface.
What is extrusive rock?
200
Process where minerals dissolved in water crystallize between sediment grains.
What is cementation?
200
Permanent change in shape by bending and folding.
What is plastic deformation?
200
An example of an igneous rock that cooled slowly. (Think Stone Mountain!)
What is granite?
300
Series of processes that change one type of rock into another type of rock.
What is the rock cycle?
300
An extrusive rock with fine-grained texture formed from quickly cooling lava.
What is volcanic glass? (Or what is obsidian?)
300
This type of rock forms when minerals crystallize directly from water. Give an example, too!
What is a chemical rock? An example could be limestone, rock gypsum, or halite.
300
This happens when magma comes in contact with existing rock.
What is contact metamorphism?
300
This happens when metamorphic rocks form over a large area deep inside Earth's crust and mantle...
What is regional metamorphism?
400
Rocks are classified in these two main ways...
What are texture and composition?
400
Igneous rocks that form as magma cools underground.
What is intrusive rock?
400
Sedimentary rock that was formed by organisms or contains the remains of organisms. Give an example, too!
What is biochemical rock? An example includes fossiliferous limestone, chert, or coal.
400
Three examples of metamorphic rocks.
What is slate, schist, and gneiss? (Marble is also an example.)
400
These characteristics are used to classify sedimentary rocks (like sandstone).
What is grain size and sediment?
500
Describe how an igneous rock can become a sedimentary rock OR a metamorphic rock.
An igneous rock (from lava or magma) could be uplifted, exposed to weathering and erosion, and then become a sedimentary rock. An igneous rock could become exposed to extreme temperature and pressure and become a metamorphic rock.
500
An example of an extrusive rock and an example of an intrusive rock.
What is granite (intrusive) and what is basalt (extrusive)?
500
Describe the process of how sedimentary rocks form.
What is erosion, transportation, deposition, compaction, and cementation?
500
State the difference between foliated and nonfoliated rocks.
Foliated rocks have parallel layers of flat and elongated minerals, while nonfoliated rocks have mineral grains with a random, interlocking texture.
500
How the three main types of rocks form... (Think about the rock cycle graphic organizer!)
Metamorphic rocks form from sedimentary rocks that are exposed to increased pressure and temperature. If the metamorphic rocks begin to melt into molten rock, they become igneous rocks. Igneous rocks can become exposed to weathering, erosion (water, wind, rain, ice) and break apart to become sedimentary rocks.
