What are the three most common ways Minerals form?
Cooling of melted Earth materials
Evaporation
Precipitation

What are four common ways we identify Minerals?
Hardness, Luster, Color, Streak, and Cleavage & Fracture, (Magnetism, reacting with acid, density, and taste)

Why is color not always a reliable property to identify minerals with? Provide an example.
Some minerals such as quarts can have multiple natural colors.
500
What is the Moh's Hardness Scale?
A standardized scale used to have references with everyday objects to how hard a mineral is.
500
What is The Rock Cycle?
The natural cycle of rocks turning from Igneous Rocks to Sedimentary Rocks to Metamorphic Rocks depending on the environmental conditions.
