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
Almost all fossils found have been of one specific species- not of intermediate links.
Why does the fossil record offer evidence for the idea that God created each plant and animal individually?
Because the life forms at the bottom were simpler life forms than those at the top.
Why is the geological column considered evidence for evolution?
The geological column is fueled by many assumptions and is never found in geology in its complete form
Why is the geological column not really evidence for evolution
No
Is it possible to go somewhere in the world and see all major layers of the geological column
Strata can form within a matter of hours.
What do the data from Mt. St. Helens tell us about the time it takes to form stratified rocks
No
If you see a canyon with a river flowing at the bottom of it, should you assume that the river eroded the canyon?
Forming strata or new geological structures.
What two things did the Mt. St. Helens eruption have that a major flood would also have?
Sometimes we find bones or other fossils that still have soft tissue on them - hard to explain if the fossil is millions of years old
Uniformitarian Problem
Uniformitarians must imagine the existence of paraconformities
Uniformitarian problem
