Rocks
All natural, solid mixture of minerals or grains.
What is a rock?
Igneous rocks that form when magma cools underground.
What is an Intrusive Igneous Rock?
An example of a Biochemical sedimentary rock.
What is Limestone?
Metamorphism that occurs when magma causes existing rock to change.
What is contact metamorphism?
A series of processes that changes one type of rock into another.
What is the rock cycle?
The fragments that make up a rock.
What is a grain?
Igneous rocks that form from volcanic material on earths surface.
What is Extrusive Igneous Rocks?
Sedimentary rocks that are made of broken rocks and minerals.
What are Clastic sedimentary rocks?
Metamorphism associated with mountain building.
What is regional metamorphism?
Metamorphic rocks form as a result of exposure to this.
What is extreme heat and pressure?
Igneous, Metamorphic, & Sedimentary.
What are the 3 types of rocks?
Igneous rocks with small, hard to see crystals.
For example, Obsidian.
What are extrusive igneous rocks.
Chemical sedimentary rocks often have this type of texture.
What is interlocking crystalline?
The permanent bending and folding of rocks without melting.
What is plastic deformation?
This is the result of pressure from the above layers or rock forcing the grains closer together.
What is compaction?
The grain size and how they fit together, used to determine the environment the rock formed.
What is texture.
Rocks with large, interlocking crystals.
For example, granite.
What is intrusive igneous rocks.
Sedimentary rocks that from when minerals crystallize from water.
What are chemical sedimentary rocks?
Metamorphic rocks that contain parallel layers of minerals.
What are foliated rocks?
The is the result of water leaving mineral deposits in between the grains of rock.
What is cementation?
The type of minerals or grains present in a rock, used to determine where a rock forms.
What is composition?
Igneous rock that has holes due to the release of gas.
What is pumice?
Sedimentary rocks that are made from the remains of organisms.
What is Biochemical Sedimentary Rocks?
Metamorphic rocks that have interlocking mineral grains.
What are nonfoliated rocks?
This rock type forms when a melted rock cools and crystallizes deep beneath Earth's surface or on Earth's surface.
What is Igneous rock?
