Gen Science Module 8 Flashcards
Fossils that are assumed to represent a certain period in earth’s past.
Index Fossils
A theoretical picture in which layers of rock from around the world are meshed together in a single, unbroken record of earth’s past.
Geological Column
A theory stating that all life on this earth has one or a few common ancestor(s) that existed a long time ago.
The Theory of Evolution
Because of the different animals from different places on earth all together in one place
why is the Cumberland Bone Cave important when it comes to the question of uniformitarianism versus catastrophism?
No
Do fossils require millions of years to form
an unconformity that geologists think should exist but doesn’t
What is a paraconformity
They are used to determine which fossils are from which time period in earth’s past
How are index fossils used by uniformitarian geologists
Specific species on the left, and different kinds of creatures span more than one time period on the right.
How is the geological column structured?
The geological column is not intact anywhere on earth
Uniformitarian problem
Things that were assumed to be extinct were found to not be extinct
Uniformitarian problem
Uniformitarians believe that rocks take millions of years to form, but the Mt. St. Helen’s eruption proved otherwise
Uniformitarian problem
some fossil structures look as if they had been formed over some time
Catastrophist problem
White Cliffs of Dover
Catastrophist problem
explanation of how unconformities can exist between certain layers of rock formed in the Flood.
Catastrophist problem
no fossils of intermediate links
Why does the fossil record offer no evidence for evolution
