Geology GE 2000 Exam 2 Questions and
100% Correct Answers
ka, ma, ga - CORRECT ANSWER-thousands, millions, billions

Catastrophism - CORRECT ANSWER-sudden & obvious to humans

Gradualism - CORRECT ANSWER-NOT obvious to humans (ex: Glaciers, plate
tectonics)

Uniformitarianism - CORRECT ANSWER-"The present is the key to the past" Earth is
shaped entirely by the same forces still in operation today, acting over a very long
period of time.

Relative Age/Time - CORRECT ANSWER-- Younger vs. Older
- the sequence of events
- "common sense" rules

Absolute Age/Time - CORRECT ANSWER-Numerical Age, Radiometric Dating

Principles for determining relative age - CORRECT ANSWER-1. Principle of
Superposition
2. Principle of Original History
3. Principle of Original Lateral Continuity
4. Principle of Cross Cutting relationships
5. Principle of Baked Contacts
6. Principle of Inclusions
7. Principle of Faunal Succession

Superposition - CORRECT ANSWER-Rock layers become younger from bottom to top

Original Horizontally - CORRECT ANSWER-Sediments were originally deposited
horizontally: sediments settle out of a fluid due to gravity and accumulate in a horizontal
fashion

Strata, after - CORRECT ANSWER-___ inclined at steep angles must have been
disturbed ___ formation.

Original Lateral Continuity - CORRECT ANSWER-Strata layers extend laterally until
they thin to nothing (pinch out) at the edge of the depositional basin.

Strata - CORRECT ANSWER-continue in all directions or until they thinned out to
nothing or they meet the boundary of their basin

, Cross Cutting relationships - CORRECT ANSWER-Younger rocks intrude older rocks

Baked Contacts - CORRECT ANSWER-igneous rocks metamorphose the surrounding
rocks and must be younger than the rocks it metamorphoses

Inclusions - CORRECT ANSWER-any piece of a rock that has become included in
another rock must be older than the host rock

Faunal Succession - CORRECT ANSWER-Fossil life has changed through time and
occurred in a definite order.
To use, the organism must have been:
+ Widespread
+ lived during a relatively short period of time
+ been abundantly preserved

Uncomformities - CORRECT ANSWER-Problem with relative dating
- "Interruptions" in the sequence
- Gaps in the geologic record due to erosion or deposition
- Not everything is preserved!

3 Main Types of Uncomformities - CORRECT ANSWER-Disconformities, Angular
Uncomformities, Noncomformities

Disconformities - CORRECT ANSWER-hard to recognize - occurs between layers of
sedimentary rocks

Angular Uncomformities - CORRECT ANSWER-obvious time break, diff. angles

Noncomformities - CORRECT ANSWER-boundary between sedimentary rocks and
crystalline rocks (igneous or metamorphic)

Grand Canyon - CORRECT ANSWER-Which rock formation has all 3 types of
conformities

1889 - CORRECT ANSWER-90 m.y. estimate of earth's age based on time needed to
get salt concentration to where it is now

1896 - CORRECT ANSWER-radioactivity was discovered

Isotope - CORRECT ANSWER-Elements with different
- # of neutrons
- Atomic weights
- Symbols (i.e. 12C, 13C, 14C)

Radioactive Isotope - CORRECT ANSWER-- Unstable
