2 A seismogram show is that P waves travel
It shows that P waves travel faster than S waves.
Where does earth's core have a high iron content comes from studying what
What can a travel time graph be used to find
A travel time graph can be used to find the distance from the
epicenter of an earthquake.
The san francisco earthquake of 1906 occurred along what fault
How much of an increase in wave amplitude is seen from an earthquake measuring 5.4 on the Richter scale compared to one measuring 4.4
Violent shaking from an earthquake can cause soil and rock on slopes to move and cause a
Violent shaking from an earthquake can cause soil and rock on
slopes to fail and cause a landslide
How many earthquakes have occurred in Hawaii
Which seismic waves compress and expand rocks in the direction the waves travel
The amount of shaking produced by an earthquake at a given location is called the
The amount of shaking produced by an earthquake at a given
location is called the intensity.

What is an earthquake's magnitude a measure of
An earthquake's magnitude is a measure of how strong it is
A succession of ocean waves set in motion by a submarine earthquake
The succession of waves is called a tsunami.

What produces a record of seismic waves
Why does the study of meteorites helps scientists to know about the interior of the earth
The study of meteorites help scientists study the interior of
the earth because it is believed that the meteorites are made up of
the same material as earth.
Which is not a factor in calculating the moment magnitude of an earthquake
magnitude of past earthquakes in the area
What is the difference of the P waves and S waves used to locate an earthquake's epicenter
P waves, also called primary waves, are the first waves to be
registered on a seismograph. The S waves, or secondary waves, are
the second and slower wave to register on the seismograph. When
locating an earthquakes epicenter seismologists take the first
reading of the P wave, and then take the reading from the S wave.
At the station of where the earthquake was recorded, seismologists
draw a large circle from where the earthquakes epicenter could be.
TO exactly located the earthquakes epicenter there needs to be at
least 3 dfferent staions where the earthquake hit to determine its
epicenter using the S and P time interval.

Which area would likely suffer the most damage from magnitude 6.8 earthquake
area with older brick structures
Why was Alfred wegeners idea that tidal forces might cause continental drift refuted as impossible
It would stop earth's rotation.
Showed that the tidal forces needed to move continents would
stop earths rotation.
What was the reason wegeners continental drift hypothesis was rejected
His evidence was incorrect.
The release of stored energy from rocks that are deformed by stress is called elastic

Is this statement true or false P waves and S waves are two kinds of seismic waves.
The Richter magnitude of an earthquake is determined from the
measurement of the amplitude of the largest seismic waves
