question

1 -How does stress in the crust change Earths surface

answer

compression tension shearing have beed changeing the shape of the earths surface for millons of years

question

1 where are faults usually found and why do they form

answer

compression and it forms moutains by pushing the rocks together

question

1 what land features result from the forces of plate movement

answer

over millions of years the forces of plates movement can change a flat plain into land froms such as synclines and anticlyne,folded moutains,fault block moutains,and platues

question

1 stress

answer

a force thats acts on rock to change the shape or volume

question

1 tension

answer

the stress that pulls the crust

question

1 compression

answer

the stress that squeezes the rocks

question

1 shearing

answer

the were the rocks go in oppposite direction

question

1 normal fault

answer

caused by tension so the rocks are pulled apart

question

1 hanging wall

answer

the rock that lies above fault line

question

1 footwall

answer

the rock that lies bellow the fault line

question

1 reverse fault

answer

has the same structre as a normal fault but the rocks/blocks are lieing in the opposite direction

question

1 strike-slip fault

answer

the rocks slide past each other in any motion

question

1 anticline

answer

the the land artches upward

question

1 syncline

answer

when the bends downward

question

1 plateau

answer

a large area of land that is located hight above sea level

question

1 how does shearing affect rock in earths crust

answer

it caues earthquakes and rubs the land together

question

1 what is the difference between a hanging wall and a footfall

answer

the footwall does not move while the haging wall moves up or down

question

1 what type of plate movement causes fault-block mountains to form

answer

compression

question

1 hows does tension change the shape of earths crust

answer

it pulls the land apart and makes valleys

question

1 compare the way that compression affects the curst to the way tension affects the crust

answer

compression forms mts tension forms vallys

question

1 why do faults often occur along plate boundaries

answer

because thats were the rocks move

question

1 what type of fault is formed when plates diverge or pull apart

answer

divergent

question

1 what type of fault is formed when plates are pushed together

answer

convergent

question

1 name five kinds of landforms caused by plate movement

answer

liquafraction land slides tsunamis fires mudslides

question

1 what are three landforms produced by compression in the crust

answer

moutains platues plains

question

1 what landform is produced by tension

answer

valleys

question

2 how does the energy of an earthquake travel through Earth

answer

seismic waves carry energy from the focus trought earths interior also it goes across the suface

question

2 what are the scales used to measure the strength of an earthquake

answer

ricter scale mercalli scale

question

2 how do scientists locat the epicenter of an earthquake

answer

they use sesmic waves

question

2 earthquake

answer

it is a shaking or trembling the results the movement of tocks under the surface of the earth

question

2 focus

answer

the point benethearths surface where the rocks break under stresswitch causes an earth quake

question

2 epicenter

answer

the point on the earth above the focus

question

2 p wave

answer

it compresses

question

2 s wave

answer

goes up and downvibrate from side to side and up and down

question

2 L wave

answer

move slowly rols like a wave motion and only goes on the land most desrutive

question

2 mercalli scale

answer

devloped to rate earthquakes acccording to the level of gamage at a given place

question

2 magnitude

answer

a nimber geoligest use to assign to an earthquake on the level of damage

question

2 richter scale

answer

based on the siz eof earthquakes sesmic waves

question

2 seismograph

answer

recods measurments of sesmic

question

2 moment magnitude scale

answer

uses both richter scale and mercilli scale

question

2 which type of seismic wave causes the ground to roll like ocean waves

answer

L waves

question

2 what kind of movement is produced by each of the three types of seismic waves

answer

vibrating

question

2 how is magnitude measured using the richter scale

answer

by giving a number of how big the earthquakes size is

question

2 what are the advantages of using the moment magnitude scale to measure and earthquake

answer

it gives total amount of the engery is realesed during an earth- quake

question

2 what type of data do geologists use to locate and earthquakes epicenter.

answer

where the crack is and where it is the most damaged

question

3 how do seismographs work

answer

they provided data to map faults and dectect changes in faults.

question

3 how do geologists monitor faults

answer

the graph dectects changes allong faults

question

3 seismogram

answer

the record of an earthquake's sesmic waves produced by a sesmograph

question

3 friction

answer

the force the opposes the motion of one surface as it moves across another surface

question

3 how does a creep meter work

answer

wires streeched across it horzotile so it measures the horozontil movement on the ground.

question

3 what four instruments are used to monitor faults

answer

tiltmeter creeep meters laser ranging meters gps satelites

question

what changes does and instrment mesure

answer

of the foult moves or any thing is tilting

question

3 why do geologists collect data on friction along the sides of faults.

answer

because earthquakes are caused by plates rubbing past each otherso if thats starting yo rub it could grow bigger

question

4 how do geologists determine earthquake reisk

answer

geolglist can determin earthquake risk by locating where faults are active and where past earthquakes have occured

question

4 what kinds of damage does an earthquake cause

answer

causes of earthquake damage icluding shacking liqufraction and after shock also tsunamis

question

4 what can be done to increase earthquake safety and reduce earthquake damage

answer

the best thing to do is to drop cover and hold

question

4 liquefaction

answer

when the ground is shaken so much that the soil turns into liquid mud

question

4 aftershock

answer

a smaller earthquake after the bigger one in the same place can be one hour orr days until there is and after shock

question

4 tsunami

answer

a large wave that forms from a earthquake under the water

question

4 base isolated building

answer

a building mouded on bearings desiged to absorb the energy of an earthquake

question

4 what area of the united states has the highest earthquake risk.

answer

hawaii anchorage los angles san fransico

question

4 what factors help geologists determine earthquake risk for a region.

answer

if there has been a earthquake there before many times, on a plate bouder

question

4 why does the risk of quakes vary across the United states

answer

beacuse some places are not near or on the bounderie of two plates

question

4 what are the 4 ways that earthquakes cause damage

answer

1~shacking 2~liqufraction 3~aftershocks 4~tsunamis

question

4 how does liquefaction cause damage during and earthquake

answer

the buildings sink and people get trapped

question

4 how might heavy rain before and earthquake affect the danger of liquefaction

answer

since the soil is already wet the shacking will make it even wetter and may sink down more

question

4 how can you protect yourself during an earthquake.

answer

drop cover and hold

question

what should you have ina an emergncy kit

answer

snacks ( non parishable) water blanckets clothes medicane gps walkey talky

question

what can happen during and earthquke

answer

fire brake out, flooods,houses collaps-sink,buildings fall

question

where would you go if you were outside in a earthquake

answer

stay there and go to a place where there is not a lot of things to fall dont go inside

question

where would you go if you were inside during a earthquake

answer

stay inside go under a sturdy table or door way make sure to get emergcy kit when earthquake is over
