SFSU ERTH 310 TEST GUIDE WITH
COMPLETE SOLUTION
According to the lecture, which definition below would be the best definition
of Geology? - ANSWER Geology is the scientific study of the Earth, Moon and
other terrestrial bodies including its origin and evolution, composition, and
the processes that act on them.
Choose the best definition for the scientific method below: - ANSWER A
systematic method that scientists use to aid in understanding phenomenon
better.
What are the key differences between a scientific hypothesis and a scientific
theory according to the lecture? Choose from the following: - ANSWER A
theory is an accumulation of many well-proven and well-accepted
hypotheses that explain why phenomenon occurs.
What are the key differences between a scientific theory and a scientific
law/principle according to the lecture? Choose from the following: - ANSWER
A law explains the process of a phenomenon, but not why it occurs like a
theory does.
According to the lecture, what energy source is Earth using primarily for its
internal processes? - ANSWER Radioactive decay
According to the lecture, what energy source is Earth using primarily for its
external/surficial processes? - ANSWER Solar energy
Which of the layers listed below is defined as a layer by composition? -
ANSWER Core
,Which of the layers listed below is defined as a layer by its physical
properties? - ANSWER Lithosphere
Of the choices below, which one represents 100% of the Earth's mantle? -
ANSWER Asthenosphere, Mesosphere and the ultramafic section of the
Lithosphere
Which layer from the choices below generates Earth's magnetic field -
ANSWER Outer Core
Which layer(s) from the choices below are defined by physical properties and
could be considered a ductile solid? - ANSWER Asthenosphere & Mesosphere
Which layer defined by physical properties is considered a liquid? - ANSWER
Outer Core
Which statement below best compares the lithosphere to the asthenosphere
according to the lecture? - ANSWER The lithosphere is a brittle solid and the
asthenosphere is a ductile solid
Which statement below best compares the crust to the lithosphere according
to the lecture. - ANSWER he lithosphere is defined by its physical property of
being brittle. The crust is defined by its composition (felsic, intermediate and
mafic)
A long, narrow linear or gently curving deep trench, earthquakes to depths of
several hundred kilometers, and volcanoes paralleling the trenches as islands.
- ANSWER Ocean-Ocean Convergent Boundary
A long, narrow linear or gently curving deep trench, earthquakes to depths of
several hundred kilometers, and volcanoes paralleling the trenches on
continents. - ANSWER Continent-Ocean Convergent Boundary
, A long, linear rise in the sea-floor with earthquakes and volcanic activity
found along its ridge. - ANSWER The correct answer is: Divergent Boundary
A land or seafloor region with many quakes right along the boundary line.
Depth of the earthquakes are shallow and the topography is not impressive
(no real large mountains or valleys). Volcanic activity is not common along
this boundary. - ANSWER The correct answer is: Transform Boundary
Transform Plate Boundary - ANSWER The correct answer is: W
Convergent Plate Boundary - ANSWER The correct answer is: Y
Island or Continental Volcanic Arc - ANSWER The correct answer is: U
Divergent Boundary - ANSWER The correct answer is: X
Shallow Focus Earthquakes - ANSWER The correct answer is: W, X, Y
Deep Focus Earthquakes - ANSWER The correct answer is: U
Ocean Trench - ANSWER The correct answer is: Y
Where do earthquake waves originate from? - ANSWER The correct answer
is: The Focus
Which type of wave below can travel through solids and liquids and is similar
to a sound wave? - ANSWER The correct answer is: P-waves
What does the S-P interval represent exactly? Choose the best answer below:
- ANSWER The correct answer is: It is the time interval between the arrival of
the P-wave and the arrival of the S-wave at a seismic station.
Eureka, CA: - ANSWER The correct answer is: 49 seconds
Elko, NV: - ANSWER The correct answer is: 72 seconds
