Total questions: 15
Worksheet time: 8mins
The composition of Earth's interior affects
how long an earthquake will last
the speed and direction of seismic waves
the location of an earthquake's focus
Earthquakes generally occur at plate boundaries, where
stress on rocks is greatest
the most rock is found
stress on rocks is low
To find the distance to an earthquake's epicenter, scientists
chart the lag time between preshocks and aftershocks
use radio wave detection devices
analyze the arrival times of the P waves and the S waves
To locate the epicenter of earthquakes, scientists use computers to
Analyze hypotheses and theories
perform triangulations based on data from seismograph stations
detect vibrations
If you are in a car during an earthquake, you should
drive toward a bridge
stop the car in a safe place
get out and run!
What happens to tsunamis as they move toward shore?
They die out
They increase in height
They decrease in height
During a major earthquake, buildings
always remain standing
do not move
may sway or collapse
Which method is NOT used to predict earthquakes?
detect changes in rock
monitor natural gas seepage
assess building damage
At what location does the first motion of an earthquake occur?
the focus
the seismic gap
the mantle
A foreshock is
a major earthquake
a small earthquake
another name for seismic gap
Why do earthquakes usually occur at plate boundaries?
The rock on the edges of tectonic plates is soft and gives in easily to various pressures
Rock in environments near tectonic plate boundaries experience great stress
The boundaries between tectonic plates have been seismically active for millions of years
What is the epicenter of an earthquake?
The location along a fault where the first motion occurs
a seismic wave that travels along the surface of Earth
the point on Earth's surface directly above the earthquake's focus
Which of the following can affect how a building responds to seismic waves?
the type of roof a building has
the type of ground beneath the building
the type of electrical system the building has
What is elastic rebound?
the sudden return of deformed rock to its undeformed shape
the gradual return of deformed rock to its undeformed shape
the sudden return of undeformed rock to its deformed shape
Which of the following do scientists study in their efforts to forecast earthquakes?
seismic gaps, rock changes, foreshocks
bird migration, animal behavior patterns, human behavior patterns
the solar system, air testing, rock samples
