GEO 101-Midterm Exam #1 Actual study
set with Questions and correct/verified
Answers
Geology - ANSWER-Investigation of Earth MATERIALS and the PROCESSES that affect them over
GEOLOGIC TIME
Why do geologists rarely conduct experiments? - ANSWER-ENORMOUS range of TIME and SPATIAL scales
Reasons to use the scientific method - ANSWER-Communication: uniform across disciplines
Repeatable: cause and effect
Accountability
Mineral - ANSWER-Naturally occurring solid, formed by geologic processes, has a crystalline structure,
and a definable chemical composition
What is the most outer layer of Earth? - ANSWER-Atmosphere
Why is the athenosphere important? - ANSWER-It leads into plate tectonics
Compare the athenosphere to the lithosphere. - ANSWER-Athenosphere: gooey
Lithosphere: crunchy
What elements are present in the atmosphere? - ANSWER-Nitrogen, water, & carbon dioxide
What are silicic (vanilla) elements like? - ANSWER-Thick, light colors, & light
(i.e. S, Al, O)
What are maac (chocolate) elements like? - ANSWER-Thin, dark colors, & dense
(i.e. Fe, Mn, Mg)
What are the three main ideas to the Plate Tectonic Theory? - ANSWER-1.) Crunchy outer layer is broken
into pieces (plates)
2.) Plates move around on top of deformable asthenosphere
3.) Plates interact at boundaries
What action does a DIVERGENT plate boundary make? Give an example. - ANSWER-Moves away
Creates new crust: "LITHOSPHERE"
Example: Mid-Atlantic Ridge (mafic crust separating)
What is DIVERGENT RIFTING? Give an example. - ANSWER-Rips continents apart
Example: Red Sea Zone (Sinai Peninsula)--silicic crust separating
What actions does a CONVERGENT plate boundary make? Give an example. - ANSWER-Moves towards
each other
Destroys crust
What causes SUBDUCTION? - ANSWER-Mafic-silicic
Mafic-mafic
What causes NO SUBDUCTION? - ANSWER-Silicic-silicic
