ESS Quiz questions 2023/85 Question and
Answers/ Graded A+
What is the wavelength of a wave? - -The length of a single oscillation of a wave
-Which travel faster: P waves, S waves, or surface waves? - -(body) P & S waves
-Which layer in the Earth is liquid iron? - -Outer core
-How many numbers does it take to describe an earthquake hypocenter in space and
time? - -4
latitude
longitude
depth
time
-A wave is a disturbance that: - -travels far through a medium while particles of the
medium move only a small distance back and forth
-What is the period of a wave? - -Time it takes for one cycle of the wave to pass a point
in space.
-Indicate which of the following is an example of a reflected wave. - -An image in a
mirror
-Which kind of fault moves in response to horizontal TENSION? - -A normal fault
-Does a fault slip more in the middle of a rupture or at the edges? - -the middle
-What powers plate tectonics? - -The cooling of the Earth
, -Which is an example of a refracted wave? - -Distortion of straw viewed through the
side of a glass of water.
-What are the three styles of tectonic boundaries? - -Convergent, Divergent, Transform
-How long does it take for a P wave to go from an earthquake's source to the far side of
the Earth? - -15 minutes
-Define just one of these three terms - an earthquake focus, epicenter, or hypocenter. -
-Earthquake focus:
The location where the earthquake BEGINS. The ground ruptures at this spot, then
seismic waves radiate outward in all directions.
Epicenter:
The point ABOVE the focus of an earthquake
Hypocenter:
The point UNDER the focus of an earthquake
-Which kind of fault moves in response to horizontal COMPRESSION? - -A thrust or
reverse fault
-What was the average survival rate within the tsunami inundation area for the 2011 M9
earthquake in Japan? - -92%
-Why are there GPS devices on the Viaduct freeway in downtown Seattle? - -The city is
watching for sinking, which triggers inspections of the road
-Which is NOT an essential ingredient of a seismometer? - -A deep borehole
