Minerals
A naturally occurring homogeneous substance
What is a mineral
Made when sedimentary and igneous rocks are changed by heat and or pressure
What are Metamorphic Rocks?
The only rocks to form from hot liquid
What are igneous rocks?
Most are composed primarily of the weathered remains of other rocks
What are sedimentary rocks?
Remains of prehistoric life are found in almost exclusively/ always in sedimentary rocks
What are fossils?
Minerals are ____ because the substance was not forms by or from a living thing

What is compression and cementing?
The basic structure of most rocks and minerals are:
What is silicon and oxygen
The way light is reflected from the freshly cut surface of a mineral
What is luster?
When rocks are altered at or near the Earths surface, as the result of contact with magma or lava.
What is contact metamorphism
Obsidian that cooled so quick that the crystals had no time to form
What is volcanic glass?
Naturally occurring cements that hold sediments together Usally composed with large sized sediments
What is cementation?
Is a ratio of the density of a substance to the density of water
