Plate Tectonic/Earthquake

Question 0

What is the motion of p waves

Answer 0

Push pull

Question 1

What are the three types of earthquake waves

Answer 1

Primary (P) secondary (S) surface (L)

Question 2

What is the motion of S waves

Answer 2

Up down

Question 3

What is the motion of l waves

Answer 3

Up down & side to side

Both

Question 4

Define and explain reverse faults

Answer 4

Happen at convergent boundaries, block of rock above fault moves up

Question 5

Define and explain normal faults

Answer 5

Happen at divergent boundaries rock above fault moves down

Question 6

Describe strike-slip fault

Answer 6

Happens at transform

Question 7

What’s an epicenter

Answer 7

Location on earths surface directly above the earthquakes focus

Question 8

What’s a focus

Answer 8

Where rocks move along fault energy is released from focus

Question 9

Why are there shallow and deep earthquakes in the world

Answer 9

Because of different plate boundaries, deepest at convergent, shallowest at divergent

Question 10

Seismometer

Answer 10

Measures and records ground motion and can be used to determine the distance which sound waves travel

Question 11

Seismogram

Answer 11

Graph with circles

Question 12

Seismograph

Answer 12

Graph used to find circles

Question 13

What is plate tectonics

Answer 13

Earths surface is made of rigid slabs of rock or plates that move with respect to each other

Question 14

Oceanic crust

Answer 14

More dense, basalt

Question 15

Continental

Answer 15

Less dense granite

Question 16

Why does subduction occur

Answer 16

Because one plate is denser so the denser plate sinks

Question 17

Features found at divergent boundaries

Answer 17

Oceans
Mid ocean ridge
Ex: Great Rift Valley in East Africa

Question 18

What is a divergent boundary

Answer 18

Plates moving away from eachother

Question 19

What is a transform boundary

Answer 19

Plates moving side by side in opposite directions

Question 20

What features are found at transform boundaries

Answer 20

Faults
Earthquakes
Ex: San Andreas fault system

Question 21

What features at cc

Answer 21

Mountains (non volcanic)

Ex: Himalayas

Question 22

What features at o-c

Answer 22

Volcanoes
Trench
Ex:Andes mtn range

Question 23

What are the features at oo

Answer 23

Volcanoes (island arc)
Trenches
Ex: Aleutians islands

Question 24

What are the 3 types of continental crust

Answer 24

Continental continental
Continental oceanic
Oceanic oceanic

Question 25

How do plates move

Answer 25

Bc convection (circulation of material cause by differences in temp and density) and slab pull and ridge push

Question 26

What is slab pull

Answer 26

As a slab of rock sinks it pulls the rest of the plate with a force called slab pull

Question 27

What is ridge push

Answer 27

Rising mantle material at mid ocean ridge creates the potential for plates to move away from the ridge with a force called ridge push

Question 28

How many instruments are needed to locate an epicenter

Answer 28

3

Question 29

Which type of fault occurs at the mid Atlantic ridge

Answer 29

Reverse

Question 30

The lines produced on paper from earthquake waves are called

Answer 30

Seismogram

Question 31

Primary wave props

Answer 31

Fastest

Can travel through all material

Question 32

Secondary wave props

Answer 32

Only can travel through solids

Question 33

Surface wave props

Answer 33

Most destructive

Can’t travel through liquid
