Earthquakes And Volcanoes

Front 1

Three different kinds of stress can occur in the crust

Back 1

Tension,compression,and shearing

Hint 1

Works over of millions of years to change the shape and volume of rock

Front 2

Pulls on the crust,stretching rock so it becomes thinner in the middle

Back 2

Tension

Hint 2

Type of stress

Front 3

Squeezes rock until it folds or breaks

Back 3

Compression

Hint 3

Type of stress

Front 4

Pushes a mass of rock in two opposite direction

Back 4

Shearing

Hint 4

Type of stress

Front 5

When enough of stress builds up in rock, creating a

Back 5

Fault

Hint 5

Is a break in the rock of the crust where rock surfaces slip past each other

Front 6

Most faults occur along

Back 6

Plate boundaries

Hint 6

Where the forces of plate motion push or pull the crust so much that the crust break

Front 7

There 3 types of faults

Back 7

Normal,reverse, and strike-slip faults

Front 15

Shearing creates

Back 15

Strike-slip faults

Front 16

Over millions of years the forces of plate movement can change a flat plain into landforms such as

Back 16

Anticlines and syniclines, folded mountain,fault-block,mountains and plateaus

Front 17

Shearing creates

Anticlines and syniclines, folded mountain,fault-block,mountains and plateaus

Front 19

A gold in rock that bends upcountry an arch is an

Back 19

Front 20

A gold in rock that bends upward into an arch is an

Back 20

Anticline

Front 21

A gold in rock that bends upward into an arch is an

Back 21

Anticline

Front 22

A gold in rock that bends downward to forms valley is a

Back 22

Syncline

Front 23

Anticline founded on many parts of the earth that fold are the cause of

Back 23

Compression

Front 24

A large area of flat land

Back 24

Plateaus

Front 25

The point beneath the earths surface where rock under stress breaks to cause and earthquake us called the

Back 25

Focus

Front 26

Was developed to rate earthquakes according to the level of damage

Back 26

Mercalli scale

Front 27

Is the rating of an earthquakes magnitude based on the size of the earthquakes seismic waves

Back 27

The richer scale

Front 28

The seismic waves are measured by a

Back 28

Seismograph

Front 29

Is an instrument that records and measures dormice waves

Back 29

Seismograph

Front 30

A rating system that estimates the total energy released by an earthquake

Back 30

Moment magnitude scake

Front 31

Arrives at a seismograph first

Back 31

P waves

Front 32

A wave right after the p wave

Back 32

S wave

Front 33

After the p wave and the S waves is the

Back 33

Surface wave

Front 34

The single point where the three circles

Back 34

Intersect

Front 35

Is the record of an earthquakes siesmic waves produced by a pattern of lines called a

Back 35

Seismogram

Front 36

An earthquake is the shaking and trembling that results from

Back 36

Movement of the rock beneath the earths surface

Front 37

Causes of earthquake damage include

Back 37

Shaking,liquefaction, aftershocks and tsunamis

Front 38

Liquid mud soft soil refers to

Back 38

Liquefaction

Front 39

A earthquake and then another right afterwards is called

Back 39

Aftershocks

Front 40

The point in the surface directly above the focus is called the

Back 40

Epicenter

Front 41

During an earthquake vibrations calked

Back 41

Seismic waves move out from the focus in all directions

Front 42

Categories of the three seismic waves

Back 42

P waves,s waves and surface waves

Front 43

Compress and expand the ground like an accordion

Back 43

P waves

Front 44

Vibrate from side to side and up and down

Back 44

S waves

Front 45

When both p waves and S waves reach the surface sometimes become

Back 45

Surface waves

Front 46

Move more slowly that p waves and S waves

Back 46

Surface waves

Front 47

Three commonly used methods of measuring earthquakes are the

Back 47

Mercado scale the rut her scale and the moment magnitude scale

Front 48

Large waces
