Uniformitarianism
Geologic process that are happening now also happened in the past
Superposition
States the bottom layer is the oldest and younger layers are laid on top
Angular
older rock on the bottom is no longer horizontal and has an angle to it
What are the three things that make a fossil an index fossil?
Live a short amount of time, are abundant, lived in many different places
What is my favorite topic to teach in science/social studies?
Rocks
Unconformity
gaps in the rock record due to layers of rock being eroded away
Inclusions
Small pieces of rock inside another rock are older than the rock around them
nonconformity
older rock is eroded and a different type of rock is laid on top
Put the groupings of the geologic time scale in order from least to greatest
Epoch, period, era, eon
What will I be teaching next year?
MATH!!!
Fault
Cross-cutting relationships
When a fault cuts through rock layers the fault is younger
disconformity
when a horizontal layer of rock is eroded and another horizontal layer of rock is laid on top
What is the geologic time scale?
A model of Earth's history from its creation
How old am I?
33
Geology

If I could travel anywhere, where would it be?
Belize
Key Bed
A rock layer used as a marker
Lateral continuity
All rock layers were laid as continuous layers
