Rock Cycle
A continuous process that describes how rocks transform from one type to another.
What is the rock cycle?
An inorganic, naturally occurring, crystalline solid with a definite chemical composition
What is a mineral?
Small pieces of rock or debris that all sedimentary rocks are made of.
What is sediment?
A substance that must cool and crystallize to form igneous rock.
What is magma?
The geologic process that causes the formation of metamorphic rocks.
What is heat/pressure?
The geological processes that turns sediment into sedimentary rock.
What is compaction and cementation?
The powder left on a white or black plate after scratching a mineral on it.
What is streak?
The geological processes that turn all rock types into sediment. (2 possible answers)
What is erosion and weathering?
The two categories of igneous rock, that describe where igneous rocks form.
What is foliated metamorphic rock?
The geological process that turns magma into igneous rock.
What is cooling/crystallization?
The way that a mineral reflects light.
What is luster?
What is organic sedimentary rock?
The type of igneous rock that forms close to Earth's surface.
What is extrusive igneous rock?
The type of metamorphic rock that does not have bands/has a uniform appearance.
What are non-foliated metamorphic rocks?
The geological process that turns an igneous or sedimentary rock into metamorphic rock.
What is heat/pressure?
A mineral with rough, uneven surfaces shows this characteristic.
What is fracture?
The geological processes (2) that turn sediment into sedimentary rock.
What is compaction and cementation?
The type of igneous rock that forms deep under Earth's surface.
What is extrusive igneous rock?
The process of rock changing into metamorphic rock due to high pressure and temperature that is spread over a large area.
What is regional metamorphism?
The geological processes required to transform metamorphic rock into sedimentary rock.
What is erosion/weathering, AND compaction/cementation?
The 4 characteristics of all minerals
What is 1. Definite chemical formula 2. Crystalline solid 3. Inorganic 4. Naturally occurring.
Another word (seen on the Gizmo) for compaction and cementation.
What is lithification?
A texture in igneous rocks where large crystals are visible, indicating slow cooling.
What is coarse-grained?
The process of rock turning into metamorphic rock due to the heat from nearby molten rock.
What is contact metamorphism?
