Igneous
Igneous rock is formed when what cools/crystallizes?
What is magma?
Sedimentary rock that is made of broken pieces of other rocks.
What are clastic rocks?
Occurs when rocks come into contact with molten rock.
What is contact metamorphism?
Type of weathering the does not change the composition of the rock.
What is physical weathering?
This type of igneous rock forms when lava cools on the Earth's surface.
What is Extrusive igneous rock?
The two main types of weathering.
What are physical and chemical?
The process of dropping sediment in a new location.
What is deposition?
The continuous changing and remaking of rocks.
What is the rock cycle?
The only rock that fossils can be found in.
What are sedimentary rocks?
This determines the size of crystals that form in igneous rocks.
What is the cooling rate of the magma or lava?
The process in which mineral growth forms between sediment.
What is cementation?
Put the following in order from least to most compactible:
sand, clay, gravel
What is gravel, sand, clay?
Metamorphic rock needs these two things to form.
What are heat and pressure?
The process of moving broken down materials to a new location.
What is erosion?
This causes coloration of igneous rocks.
What is mineral content?
The four main types of erosion.
What are wind, glacial, water, and gravity?
The percentage of open spaces between grains in a rock.
What is porosity?
Metamorphic process that requires hot water.
For an Igneous rock to become a sedimentary rock, what needs to happen?
What is weathering, erosion, compaction, and cementation?
The term that describes the holes left in rocks by gas bubbles.
What is vesicular?
Form when inclined layers of sediment are deposited along a horizontal surface. Over time, these deposits can become lithified.
What is cross-bedding?
The process by which sediment is turned into sedimentary rock.
What is lithification?
Metamorphism that results from high temperature and pressure that affects are large area.
What is regional metamorphism?
The four main factors that affect magma formation.
What are temperature, pressure, mineral content, and water content?
