GEO 401: Test One Review (Dr.
Befeus) Questions and Answers
(100% Correct Answers) Already
Graded A+
Superposition Ans: layers stacked sequentially, young layers

cover old layers
Guru01 - Stuvia
Original Horizontality Ans: Principle stating that sedimentary
Expert
rocks are deposited in horizontal or nearly horizontal layers.
Any changes from that was produced by geological forces
Cross-Cutting Relationships Ans: Principle stating that a fault
or intrusion is younger than the rock it cuts across.
Uniformitarianism Ans: A principle stating that current
geologic processes can explain past geologic events.
What does uniformitarianism suggest? Ans: The present is the
key to understanding the past in terms of geologic processes.
Topography Ans: Contour lines are levels of equal elevation
Climate Ans: Range in weather conditions for an area over a
period of decades
Climate Change Ans: Long term change for a region
, 2
Global Warming Ans: An increase in the average temperature
of the earth's atmosphere compared to the baseline
temperature
Greenhouse Gases Ans: Gases such as carbon dioxide (CO2),
methane (CH4), nitrous oxide, water vapor (H2O), and ozone in
the atmosphere which are involved in the greenhouse effect.
Greenhouse Effect Ans: Natural situation in which heat is
retained in Earth's atmosphere by carbon dioxide, methane,
water vapor, and other gases and can't not get out

3. Ice is melting from ice sheets and glaciers
4. Sea level is rising by around 3 mm/year
5. More extreme weather
6. Climate zones are shifting ploewards
7. CO2 is rising in the atmosphere
Proxy Ans: Signature of change preserved in rock records (Ex:
Fossils, trees, Ice cores)
