Faults/Boundaries/forces

Question 1

What are 3 types of faults?

Answer 1

Strike-Slip, Normal, Reverse

Question 2

What kind of boundary is at a Strike-Slip fault?

Answer 2

Transform Boundary

Question 3

What kind of boundary is at a Reverse Fault?

Answer 3

Convergent Boundary

Question 4

What kind of boundary is at a Normal Fault?

Answer 4

Divergent Boundary

Question 5

The most sever type of earthquake occurs at an ____ fault

Answer 5

reverse

Question 6

You would expect to see a ____ as a result of an earthquake at a Reverse Fault

Answer 6

mountain

Question 7

You would expect to see a ____ as a result of an earthquake at a Normal Fault

Answer 7

valley

Question 8

Define an earthquake

Answer 8

An earthquake is caused when two plates snag against each other and after a long time release the pressure and energy built up.

Question 9

Define a Focus

Answer 9

The first area where the earthquake and shaking starts underground.

Question 10

Define and Epicenter

Answer 10

The area above the focus where the most damage and shaking occurs.

Question 11

Define a Primary Wave

Answer 11

The fastest and least damaging waves. P waves come first. Compress the rocks.

Question 12

Define a Secondary Wave

Answer 12

A secondary wave is the second most destructive and they are slower than p-waves. They come second. Move in an S-shape / rocks move perpendicular to the flow of energy

Question 13

Define a Surface Wave

Answer 13

The surface waves come third and are the most destructive and slow. They come third. Move over the surface outward from the epicenter. (Rayleigh / Love)

Question 14

Define the Richter Scale

Answer 14

Richter measures the strength of an earthquake but doesn’t tell the damage.

Question 15

Define the Mercalli Scale

Answer 15

The Mercalli measures the damage but not the strength of the quake.

Question 16

Wave: Speed: Fastest

Answer 16

Primary/P

Question 17

Wave:Secondary/S Speed:

Answer 17

Second Fastest

Question 18

Wave: Speed:Second Slowest

Answer 18

Rayleigh (Surface)

Question 19

Wave:Love (Surface) Speed:

Answer 19

Slowest

Question 20

Forces that changes rock shape or volume is called

Answer 20

stress

Question 21

Reverse faults have __________________ and folding that formed the Alps and Himalayas.

Answer 21

compression

Question 22

________________ pulls on crust which results in a normal fault.

Answer 22

tension

Question 23

__________________ fault squeezes rock to form the Rocky Mountains.

Answer 23

reverse

Question 24

Strike-slip fault has a ______________________ boundary.

Answer 24

transform

Question 25

Rocks become twisted and strained when they snag each other on a convergent boundary.

Answer 25

False

Question 26

In a normal fault, rocks above the fault surface are forced up and over rocks below the fault surface.

Answer 26

False

Question 27

The San Andreas Fault is an example of a reverse fault.

Answer 27

False

Question 28

Normal faults occur at a divergent boundary.

Answer 28

true

Question 29

Reverse fault has a ______________________ boundary.

Answer 29

convergent

Question 30

Normal fault has a ______________________ boundary.

Answer 30

divergent

Question 31

_______________ stress occurs at a normal fault.

Answer 31

tension

Question 32

_______________ stress occurs at a reverse fault.

Answer 32

compression

Question 33

_______________ stress occurs at a strike-slip fault.

Answer 33

shearing

Question 34

Normal faults ______________________ at an angle.

Answer 34

pull apart

Question 35

Reverse faults ______________________ at an angle.

Answer 35

push together

Question 36

Reverse faults ______________________ at an angle.

Answer 36

sliding past each other
