100
This is used to order things by comparison.
Relative Dating
100
Breaks in Earth's crust
Faults
100
Why are faults always younger than the rock layers they cut through (other than crosscutting)
The rock must be their first in order to be split.
100
When fossils are covered with smaller pieces of rock over time...
Buried in sediment
100
This is the slow-flowing layer Earth's surface.
Mantle
200
This states that older rock is found towards the bottom of rock layers and younger rock is found towards the top.
Superposition
200
Anticlines and Synclines
Folding
200
What type of rock always forms an intrusion?
Igneous
200
This is when sticky tree sap covers an organism and hardens.
Trapped in Amber
200
This is how metamorphic rock forms.
Heat and Pressure
300
These are remains of living things that have been preserved over time.
Fossils
300
Rock layers become slanted due to this.
Tilting
300
What is true about fossils and the layer of rock they are found in?
They are the same age.
300
This is when sticky pools of tar harden around an organism.
Trapped in Asphalt
300
This is the most dangerous location of an earthquake.
Epicenter
400
This is an ordered arrangement of rock layers that geologists use to compare different rock layers.
Geologic Column
400
This is when there is a "gap" in a series of rock layers.
Unconformity
400
How are rock layers that are undisturbed normally distributed?
Horizontally/evenly
400
This is when minerals replace the tissue of a once living organism.
Petrified
400
What are the three types of volcanoes?
Shield, Cinder Cone, Composite
500
This law states that any fault or intrusion must be younger than the rock layers they cut through.
Crosscutting
500
When magma rises up through rock layers and hardens.
Intrusion
500
What process is most responsible for rock layers forming?
Deposition
500
This prevents bacteria from growing on an organism and prevents decay
Frozen
500
What process drives plate tectonics?
Mantle Convection
