The main three steps of processes that sedimentary rocks undergo.
What is deposition, compaction, and cementation.
100
Contains parallel layers of flat and elongated minerals.
What are foliated rocks?
100
Igneous rock that forms as magma cools underground
What are intrusive rocks?
100
The series of processes that change one type of rock into another.
What is the rock cycle?
100
Molten or liquid rock underground.
What is Magma?
200
Sedimentary rock that was formed by organisms or contains organisms.
What are biochemical rock?
200
Metamorphic rocks that have mineral grains with a random interlocking texture.
What are Nonfoliated rocks?
200
Igneous rock that forms when volcanic material erupts, cools and crystallizes on Earths surface.
What are extrusive rocks?
200
A broken piece of rock or fragment that makes up a clastic rock.
What are clasts?
200
Is always a mixture of minerals, organic matter, volcanic glass, or other materials.
What is a rock?
300
Sedimentary rocks that are made up of broken pieces of minerals and rock fragments.
What are clastic rocks?
300
The formation of a metamorphic rock caused by magma coming into contact with existing rock.
What is contact metamorphism?
300
Two characteristics to help identify igneous rocks.
What is grain size, and texture?
300
Any process that affects the structure or composition of a rock in a solid state as a result of changes in temperature, pressure, or the addition of chemical fluids.
What is metamorphism?
300
The sedimentary rock formed by fast moving rivers or streams that have polished the grains.
What is conglomerate rocks?
400
Sedimentary rock that forms when minerals crystallize directly from water.
What are chemical rocks?
400
Formation of metamorphic rock bodies that are hundreds of square kilometers.
What is regional metamorphism?
400
Causes rocks to be light or dark in color.
What is silica.
400
The mechanical and chemical processes that change Earth`s surface over time.
What is weathering?
400
Forms when lava cools to quickly to create grains.
What is volcanic glass?
500
A biochemical rock that is composed of the remains of plants and animals from prehistoric swamps.
What is coal?
500
The bending of rocks when rocks experience an increase in temperature and pressure.
What is plastic deformation?
500
Underground magma contains this.
What are dissolved gases?
500
The permanent change in shape by bending and folding.
What is plastic deformation?
500
The type of scientist that analyzes the composition of rocks.
