Earthquakes pt 2

Question 1

list the effects of earthquakes

Answer 1

damage to homes and structures
tsunami
new land
ash
climate change
disrupt society

Question 2

p wave

Answer 2

first wave of energy
push and pull
compression/longitude
travels through body of earth

Question 3

s wave

Answer 3

second wave of energy
transverse/side to side
cant travel through liquid
moves through body of earth

Question 4

surface wave

Answer 4

travels along surface

side to side

Question 5

what are three ways in which the earth’s plates move

Answer 5

collide (convergent)

seperate (divergent)

slide (transform)

Question 6

how do mountains form

Answer 6

continental plates converge (ex. Himalayas)
divergent plate boundary (ex. mid-atlantic ridge
volcanic activity
oceanic and continental plates converge, creates subduction zone and uplifting

Question 7

why do earthquakes occur along a fault

Answer 7

transform plates grinding past each other

Question 8

why are there so many ridges and cracks along the san andreas fault

Answer 8

ductile–land bends before breaking -> ridges that form

Question 9

how do scientist know the inside of the earth is made of layers

Answer 9

secondary wave cant move through liquid
primary wave can

study of earthquake seismic waves

Question 10

what evidence do scientists have to support the idea that the continents were once one large landmass
what caused the large landmass to seperate

Answer 10

shapes of continents fit together
convection currents move plates and cause seafloor spreading
geological features (mountains, glaciers, fossils)
plate tectonic theory

Question 11

what are the causes of earthquakes?

Answer 11

shifting tectonic plates
movement along faults
large and sudden releases of energy
magma movement
landslides
