Recognized founder of the study of Geology and Scottish farmer
Who is James Hutton
100
Material comprised of tree sap that protects and preserves once living organisms.
What is amber
100
Process where a radioactive element "breaks" down into a stable element
What is decay
100
The largest division of geologic time
What is an Eon
100
An unconformity that results when a rock layer is partially or completely missing from the rock column.
What is a disconformity
200
Theory that suggests that Earth has been shaped by a series of global events.
What is Catastrophism
200
Any natural preserved evidence of animal activity such as a foot print.
What is a trace fossil
200
The time needed for 1/2 of the radioactive material to decay
What is half-life
200
The smallest division of geologic time
What is an Epoch
200
The process where material is worn down by wind, water, or other elements
What is erosion
300
Undisturbed rocks are laid in this pattern
What is horizontal
300
An important index fossil that was tri-lobed and is related to the present day horse-shoe crab.
What is a Trilobite
300
Name for the stable element that results from decay of the parent material
What is daughter isotope
300
The Epoch that the Earth is currently in that began 10,000 years ago
What is the Holocene
300
An unconformity that is caused when igneous rock pushes up the rock column between cracks and crevices.
What is an intrusion
400
Principle that states the oldest rock layer is at the bottom and the relative age decreases as you go towards the top of the rock column.
What is Principle of Superposition
400
a 3 dimensional object created when sediment fills and hardens in a hollow cavity left by a once living organism.
What is a cast
400
Type of radioacative material in ALL living things
What is Carbon-14
400
The major event that marks the begining of the Holocene
What is the last ice-age
400
This unconformity results when rock layers are disturbed and caused breakage of the layers. Movement of the layers also disturbs the original rock column
What is a fault
500
The process that involves the comparison of rock layers with others in a sequence to determine its age.
What is relative dating.
500
preserved animal dung (feces)
What is corpolite
500
Number of half-lives that have occured if there is 6.25% of parent isotopes and 93.75% isotopes remaining.
What is the 4th half-life
500
The age of the Reptiles (Dinosaurs)
What is the Mesozoic Era
500
The wall of a fault that normally slides down the opposite wall. The surface extends over the base
