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 dogs do I have?

Igneous rock comes from the cooling of (two words!)...
magma or lava
This refers to the way a mineral's surface reflects light

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.
