Oceanic- under ocean, thin, more dense
Lithosphere
Tectonic plate, crust, upper mantle
Asthenosphere
Where convection currents take place

Mantle
Semi liquid rock, thick, silly putty material
Outer Core
Liquid
Nickel
Iron
Inner Core
Solid
Iron
Nickel
Divergent Boundaries
Exists between two tectonic plates that are moving away from each other
Convergent Boundaries
Area where two or more lithospheric plates come together/collide
Transform Boundaries
Occurs when two tectonic plates move past one another
Normal Fault
When hanging wall moves below your foot wall
Reverse
Footwall move below your hanging wall
Strike Slip
Slide past each other
Focus
Where an earthquake is started, located sort of in the middle
