fossils
The type fossil is formed from the actual remains of an organism.
What is a body fossil?
The largest division of geologic time.
What is an eon.
The theory of the movement of earth's lithospheric plates.
What is plate tectonic theory?
This is what the laws of superposition are used for.
What is to determine the order of layers of crust/age?
The best example of cast fossils.
What is a trilobite?
The era in which dinosaurs were dominant on earth.
What is the Mesozoic era?
The 3 types of plate boundaries.
What is convergent, transform, and divergent?
This law states that if rock layers are tilted or folded then those layers are older.
What is law of original horizontality?
This is a fossil that is tracks, burrows, or prints.
What is trace fossil?
The time period in which simple mosses, ferns, and cone bearing plants made up the majority of the earth.
What is Paleozoic era?
This boundary is where earthquakes typically occur.
What is transform boundary?
This law states that is layers go across other layers then they are younger
What is law of cross cutting relationships?
How can fossils help us understand the environment of ancient earth?
What is telling us about life on earth during the time period.
The type of dating that requires carbon half lives to be present and measured.
What is absolute dating/carbon dating?
What is as the plates move away so does the crust with them.
This law states that the layers near the tops of the section are the younger layers.
What is law of super position?
The significance of index fossils in dating rock layers.
What is researchers can identify relative age of rock using organisms that lived for short period of time.
The difference in relative and absolute dating.
What is shifts entire landscape slowly over time or rapidly during a major geologic event?
The layer that is the youngest.
What is B?
