Rocks
How are rocks classified?
Based on how they're formed
Density =
mass/volume
How does metamorphic rock form?
Heat & Pressure
We determine a mineral's hardness by referencing the...
Mohs Hardness Scale
How many cats do I have? (Hint: I rehomed 2 kittens)
23
Trace fossil
List 2 properties of minerals
Streak, luster, fracture, cleavage, fracture, density, color, crystal structure, special properties
Igneous rock comes from the cooling of (two words!)...
magma or lava
This refers to the way a mineral's surface reflects light
luster
What is my favorite category of science?
Chemistry
Intrusive and Extrusive
Cleavage
What must any type of rock undergo in order to become metamorphic?
Heat and pressure
I found a rock sample. It is light, porous, and has no visible crystals. What type of rock do you think it is? (BE SPECIFIC!)
Extrusive igneous rock
Name two of my cats' names
Many possibilities
A type of metamorphic rock with bands present on it would be considered....
Foliated
nonliving
What must happen to any type of rock in order to become igneous?
Melting and cooling.
What are some ways to describe a mineral's luster? (at least two!)

Which cat terrorizes me 24/7, making it difficult for me to enjoy life?
Moo Moo
A type of igneous rock that formed by magma cooling and solidifying slowly over time would be...
intrusive (inside the earth!!!)
What are all 5 characteristics of minerals?
naturally occurring, inorganic, solid, chemical composition, crystal structure
How can any other rock become a sedimentary rock?
First, weathering and erosion will break the rock down into sediment. Then the sediment must be cemented and compacted.
If a mineral is scratched by a metal nail but not by a fingernail, what range could it be on the Mohs Hardness Scale?
2.5-6.5
