Sedimentary
What is sediment?
Small pieces of rocks that are moved and deposited by water, wind, gravity, and glaciers.
What is metamorphism?
Metamorphism means that it has been changed
What is erosion?
The removal and transport of sediment.
What are three grain types of a clastic rock?
Coarse, medium, and fine.
What is an example of an intrusive igneous rock?
Diorite
What are sediment features?
Angled/round fragments and ripple marks.
What are two common minerals in metamorphic rocks?
2 common minerals in metamorphic rocks are sillimanite and garnet
What is weathering?
A physical and chemical process that breaks rocks into smaller pieces.
What is the sediment type in each type of grain?
Coarse=pebble
Medium=grain of sand
Fine= particles of silt
What causes sediment to drop?
When a sediment is dropped on the ground to the bottom of a body of water?
How is sediment squeezed together?
Sediment is squeezed together by the weight of overlying sediments forcing the sediment grains closer
What conditions are necessary for metamorphism?
Immense heat and pressure, the heat necessary for metamorphism comes from earth's internal heat, deep burial or, igneous intrusions nearby. And the pressure required comes from deep burial or compression from mountain building
Eroded material is almost always carried...
Eroded material is almost always carried downhill.
What are two kinds of rocks in the clastic family and each type of grain?
Coarse=conglomerate breccia
Medium=sandstone arkose
Fine=siltstone
What is lithification?
The physical and chemical process that transform sediments into sedimentary rocks?
What are three types of sedimentary rocks?
Clastic, biochemical, and chemical.
_______ texture is classified by layers and bands of minerals.
_________ metamorphic rocks are composed mainly of minerals that form with blocky crystal shapes.
Foliated texture is classified by layers and bands of minerals.
Non-foliated metamorphic rocks are composed mainly of minerals that form with blocky crystal shapes
Which of these thee common minerals (quartz, feldspar, and mica) will be resistant to chemical weathering the most?
Quartz.
Whats an example of a rock in the clastic family with a very fine grain?
Shale
How is cross-bedding formed?
Corss-bedding is formed as inclined layers of sediment are deposited across a horizontal surface.
Sediment gets cemented together by minerals such as.
Calcite and Silica.
_______ metamorphism is the process that affects large areas of earth's crust producing belts classified as low medium or high grade depending on pressure on the rocks , temperature, and depth below the surface
_______ metamorphism is the local effect that occurs when molten rock meets solid rock.
Regional metamorphism is the process that affects large areas of earth's crust producing belts classified as low medium or high grade depending on pressure on the rocks , temperature, and depth below the surface
Contact metamorphism is the local effect that occurs when molten rock meets solid rock.
