Why do
plates
move?

because of
convection currents
where are convection currents
where the inner core heats the mantle, causing magma to rise up
Which direction do
plates
move in?

Towards eachother (
destructive
)
Away (
constructive
)
What happens when the
plates
move?

The
oceanic crust
sinks under the
continental crust
because it's heavier
How does this movement cause an
earthquake
and/or a
volcano


As the
plates
move they get stuck and pressure builds up. When this is
released
it forms an earthquake
Destructive


plates
move towards eachother
Constructive


Plates
move away from each other
What are the
3ps


Predict
,
protect
,
prepare
Depth


A
shallow
earthquake means the shaking is more violent
Distance


A closer
earthquake
means the shaking is more violent
Secondary hazards


More secondary hazards means more
death
and destruction
What does
soft rock
do during
earthquakes


Soft rock
vibrates
more during an earthquake
Is it better to be awake or asleep during one
If people are asleep they are more likely to
die
Magnitude


The stronger the
earthquake
the more damage
Population density


The higher the population density the more
deaths
that will occur
Level of development


LICs
have less emergency services whereas
HICs
have more so HICs are more likely to
survive
