Formation Of Sedimentary Rocks
The formation of sedimentary rocks begins when __________ and ___________ produce sediments.
What is weathering and erosion?
This type of sediment particles are similar in size.
What is sorted?
When temperature and pressure combine and change the texture, mineral composition, or chemical composition of a rock without melting it, a __________ _______ forms.
What is metamorphic rock?
(Meta = Change; Morphe = Form)
Small pieces of rocks that are moved, deposited, and then glued together.
What are sedimentary rocks?
This is a course grained clastic rock that contains angular fragments.
What is breccia?
Sedimentary rocks usually form in _______.
What is layers?
The most common sedimentary rock which are formed from the abundant deposits of loose sediments that accumulate on Earth's surface. (formed from the erosion and transport of rock segments)
What is clastic sedimentary rock? (clastic = klastos = "broken")
__________ is formed by the metamorphism of limestone or dolmite.
What is Marble?
This is formed as incline layers of sediment are deposited across a horizontal surface.
What is cross-bedding?
A process that forms salt beds.
What is evaporation?
Lithification begins with _______________.
What is compaction?
This type of sedimentary rock is course-grained with rounded fragments.
What are conglomerates?
This texture of metamorphic rock is created by high pressure that is applied from opposite directions. The pressure created layers and bands where the long axes of their minerals are formed perpendicular to the pressure that altered them.
What is foliated?
This is the placement of a body of magma into a preexisiting rock.
What is intrusion? (ex: igneous intrusion)
The most abundant biochemical sedimentary rock; composed primarily of calcite and is formed from the remains of once living organisms.
What is limestone?
___________ occurs when mineral growth glues sediment grains together into solid rock.
What is cementation?
These are the layers of chemical sedimentary rocks that form from precipitated minerals when the concentrations of dissolved minerals in a body of water reach saturation due to the evaporation of water; crystal grains can precipitate out of the solution and settle to the bottom.
What are evaporites?
This occurs when molten material comes in contact with solid rock.
What is contact metamorphism?
This is the continuous changing/set of processes and remaking of rocks.
What is the rock cycle?
When temperature and pressure affect large regions of Earth's crust, they produce large belts of ________ _________.
What is regional metamorphism?
This type of bedding has the heaviest and coarsest material on the bottom.
What is graded?
The formation of chemical and biochemical rocks involve the process of _________ and ________ ___ ________.
What is evaporation and precipitation of minerals?
The type of metamorphism that occurs when very hot water reacts with and alters the mineralogy of rock is _______.
What is hydrothermal?
This is the percentage of open spaces between grains in a rock.
What is porosity?
NaCl is ______.
What is Halite/Rock Salt?
