A soil associated with the hot and wet tropics is

laterite

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

meteorites

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

San Andreas 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

Ten times

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

1,526,578

Which seismic waves compress and expand rocks in the direction the waves travel

P Waves

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.

The tsunami warning system protects coastal areas around the

pacific ocean

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.

A building that settles unevenly after an earthquake is evidence of

It may be a sign of liquefaction.

What produces a record of seismic waves

seismogram-

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 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

shock

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

magnitude

Is this statement true or false P waves and S waves are two kinds of seismic waves.

True

The Richter magnitude of an earthquake is determined from the

measurement of the amplitude of the largest seismic waves

How do ancient glacial deposits in Africa India Australia and South America support the idea of continental drift
