A soil associated with the hot and wet tropics is
Where does earth's core have a high iron content comes from studying what
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
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
What produces a record of seismic waves
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 location would have the most short-term risk of an earthquake
An Area along an active fault that has not had recent earthquake
activity(:
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
Which area is most likely to be the safest during a major earthquake
area with granite bedrock
The trace that records an earthquake from seismic instruments is called a
How do ancient glacial deposits in Africa India Australia and South America support the idea of continental drift
