200
Principle of Relative-Age Dating that states:

Correlation
300
Principle of Relative-Age Dating that states:
"If a rock layer contains pieces of rock from a different layer, the pieces of rock are older than the layer they are in."

DAILY TRIPLE! (200 points each!)
Give 3 criteria for a fossil to be considered an "index fossil."
1) they existed for a relatively short time
2) they were abundant (lots of them)
3) they were found in many locations across Earth (different continents)
300

Unconformity
300
This era of time is known as being the "age of the dinosaurs."
Mesozoic
400
A/an __ unconformity occurs when rock layers get forced up and are no longer horizontal.
angular
400
Principle of Relative-Age Dating that states:
"Most rock-forming material is deposited in flat layers."

Superposition
400
Principle of Relative-Age Dating that states:
"Sediments are deposited in large sheets in all outward directions."
Ex: layers across a canyon were once connected
