ACING EAPS 100, EXAM 2 WITH ESSENTIAL A+
QUESTIONS AND ANSWERS
These wave(s) can pass through the core
P wave
These wave(s) cannot pass through the core
S waves
Surface waves
When does reflection occur?
Reflection occurs when a seismic wave reaches a rock layer boundary and does not
cross over. Instead, the energy of its seismic wave is redirected back into the rock layer
it has been traveling through
When does refraction occur?
Refraction occurs when a seismic wave crosses a rock layer boundary, but changes
direction in the process.
If a wave refracts toward the plate boundary, which plate is more rigid?
The bottom plate is more rigid.
Three of the following statements are wrong. One is correct. Which of the
following statements is correct?
P and S waves travel through liquids, but P waves do not travel through solids.
P and S waves travel through liquids, but S waves do not travel through solids.
S waves travel through solids, but only P waves travel through liquids.
P waves travel through solids; S waves do not.
S waves travel through solids, but only P waves travel through liquids.
What is the primary reason for the elevated position of the oceanic ridge system?
The oceanic lithosphere at the ridge is hotter than the older lithosphere that is farther
form the ridge. Because the hotter lithosphere at the ridge is less dense than the cooler
lithosphere farther away, lithosphere is more elevated at the ridge, sinking as it cools
while moving away from the ridge.
How are deep-ocean trenches related to plate boundaries?
, Deep-ocean trenches are sites of plate convergence where an oceanic plate subducts
under another plate.
Where are tectonic plates located?
Earth's surface
What are the three types of plate boundaries?
divergent, convergent, transform
Which of the following statements about earthquakes with magnitude greater
than 4.0 is correct?
Earthquakes with magnitude greater that 4.0 occur in a pattern than correlates
loosely with plate boundaries.
Earthquakes with magnitude greater that 4.0 occur in a pattern than correlates
closely with plate boundaries.
Earthquakes with magnitude greater that 4.0 occur in a pattern than correlates
loosely with hot spots.
Earthquakes with magnitude greater that 4.0 occur in a pattern than correlates
closely with hot spots.
Earthquakes with magnitude greater that 4.0 occur in a pattern than correlates closely
with plate boundaries.
Which plate boundary type is not associated with volcanic eruptions?
transform
Which phenomenon can explain the presence of volcanoes in the middle of the
Pacific Ocean?
hot spots
Which type of plate boundary is most closely associated with uplifting
continental regions and mountain building?
convergent boundaries
rank the three different plate boundary types in terms of the severity of the
earthquakes they produce, from highest to lowest
convergent, transform, divergent
Most earthquakes near coastlines occur along this type of boundary
