Igneous Rock
This is molten rock found below the earth's surface.
What is magma?
tiny pieces of rock, sand, shells, etc. is called what
What is sediment?
Metamorphic rocks are formed due to _______ and _______.
Heat and Pressure
The interrelationship among three types of rocks by a series of process in which rock forms.
Rock Cycle
Igneous Rock are classified based on their _________ and ____________.
Texture and composition
Tell me about a lab we did in class that showed the different types of rocks and how they change.
Experiments include crayon lab
This is molten rock found above the earth's surface.
What is lava?
Weathered bits of rock and minerals are classified as:
A. Clastic
B. Bioclastic
C. Chemical
A. Clastic
Contact metamorphic rocks are formed when what flows through it
Magma
What type of rock is affected most by weathering?
Sedimentary
Igneous
Metamorphic
Sedimentary
Caused by slow cooling resulting in larger crystals.
A. coarse grained texture
B. fine grained texture
C. porphyritic texture
A. coarse grained
When did you observe igneous rock in the crayon lab that we did?
When the crayon was first observed as a whole cooled piece of wax
True or False: Igneous Rocks can change into metamorphic and sedimentary rocks.
True
Newer layers sedimentary rocks on the bottom. True or False.
False
Foliated
When sediments go under compacting and cementing processes they become which type of rock.
Sedimentary rocks.
True or False: Glassy texture has no crystals due to rapid cooling.
True
When did you observe metamorphic rock in the crayon lab that we did?
When heat and pressure were applied to the crayons.
Igneous rocks can be found
A. On the Earth's surface
B. Underneath the earth's surface
C. Both A and B are correct
C. Both A and B are correct
This type of sedimentary rock forms when dead plants or animals and is compacted and cemented in the rock as fossils.
Bioclastic/organic sedimentary rock
Regional Metamorphic rocks form mountains due to:
Tectonic Activity
What is erosion?
The removal of sediment from on place to another
Composition is high in silica and light in color.
A. Basaltic
B. Granitic
C. Ultramafic
B. Granitic
When did you observe sedimentary rock in the crayon lab?
When the crayon was compacted and cemented
True or False: Igneous rocks are formed when sediments break apart. If false, please correct the statement.
True or False?
When an agent of erosion loses energy and drops sediment
Deposition
Which experiment represented a Metamorphic Rock?
A. Using the blow drier, and applying pressure
B. Melting the chocolate and allowing it to cool
C. Breaking the pieces into smaller particles
A. Using the blow drier, and applying pressure
Igneous and metamorphic rocks are formed by what type energy process?
Earth's Interior: heat, magma, lava, pressure, plate tectonics
Combination between granitic light-color minerals and basaltic composition dark-colored minerals.
Andesitic
Erosion and weathering
