Chemistry Basics
This is the building block of minerals
Elements
True or False: All minerals have at least one cleavage planes when they break.
False!
This type of rock forms from cooling lava or magma.
What is Igneous?
This is the process of squeezing sediments and removing the water.
What is compaction?
In this class, tests and quizzes are worth ____% of your total grade
60%
These are all three of the subatomic particles of an atom WITH their charges & locations listed
What are Proton (positive, nucleus), Neutron (neutral nucleus), & Electrons (negative, outside of nucleus)
This is the resistance of a mineral to being scratched & the scale used
What is hardness & the Moh's scale
Between these options:
Extrusive Igneous Rock
Intrusive Igneous Rock
Metamorphic Rock
Which is the only one that can form on the surface of Earth?
What is Extrusive Igneous rock?
A metamorphic rock can become magma through this process.
What is melting?
This process was modelled in our rock candy cycle lab by the cooling of the molten starbursts after you took them off the hot plate
What is crystallization.
This is an atom that has gained or lost an electron or multiple electrons
What is an Ion?
This is the color of the powdered mineral.
What is streak?
Igneous rocks that are dominated by dark colored mineral grains that you can see without magnification are called: (2 things)
What is mafic & Coarse Grained
This is the major process in the formation of clastic sedimentary rocks. (it's not compaction!)
What is cementation?
This is a piece of evidence on a sedimentary rock that indicates the rock formed along a body of water, such as the rocks in missoula forming along the glacial lake missoula
What are ripple marks?
This is the smallest particle of an element that still retains all the element’s properties.
What is an Atom?
A mineral that doesn't have any cleavage planes is said to have this.
What is fracture?
In sedimentary rock layers, this is the layer that is the oldest in undisturbed rock layers.
What is the bottom?
This rock-forming process occurs when hot magma forces its way into rock.
contact metamorphism
These two things are the drivers of weathering, erosion and deposition
the sun & gravity
The atomic mass is the sum of these two things
What is the # protons + # neutrons?
These are the 5 criteria of a mineral
What are:
1. solid when formed
2. has a repeating 3D crystal structure
3. has a specific chemical composition
4. Naturally occurring
5. Inorganic
An igneous rock that has grains too small to see without magnification is said to have formed from this substance.
What is lava?
A metamorphic rock can become sediment through this process.
What is weathering?
This type of rock is formed from the precipitation of minerals out of water solution as the water evaporates. Be specific.
What are chemical sedimentary rocks?
