What are the 3 primary layers of the Earth defined by composition?
-Iron & Nickel
What are the 5 main layers of the Earth defined by physical properties?
Lithosphere - Solid Rock
Astenosphere - Melting
Mezosphere - Solid
Outercore - Liquid
Innercore - Solid
List, describe, and give examples of the 3 rock types.
Igneous - Rocks that form as magma cools and crystallizes.
Sedimentary - Formed by the lithification of sediments
-Sandstone, Limestone, Shale
Metamorphic - Formed from preexisting rocks by metamorphism(high temperature pressure)

The geologic processes we see in action on Earth today have worked in much the same way throughout the geologic past.
