What does 0 represent on the geologic time scale
Present time
Law of Superposition
The youngest layer is on the top and the oldest layer is on the bottom
Principle of original horizontally
Sediment is deposited horizontally
Principle of cross-cutting relationships
younger features cut through older features
Principle of lateral continuity
Sedimentary beds originate as continuous layers that extend in all directions
Unconformities
breaks in the rock record
Angular unconformity
tilted rocks are overlain by flat lying rocks
Nonconformity
Metamorphic or igneous rocks are below
younger sedimentary rocks are above
Disconformity
Strata on either side are parallel
Inclusions
one rock contained within another (rock containing inclusions is younger)
What type of plate boundaries create deep earthquakes?
At convergent boundaries because subduction zones are created.
Lithosphere
the "plate" layer
Asthenosphere
where the plates float on
Crust
two first layers
Mantle
next three layers after the crust
Oort Cloud
where comets come from and are long period
Kuipers Belt
where comets come from and are short period
Tropic of Cancer
23 degrees North
