Plate Boundaries Earthquakes
Volcanoes
The outer most layer of the
Earth
The Crust
The layer of the Earth under the
crust that is a thick, hot liquid.
The Mantle
A very hot layer inside the Earth
that is made up of liquid iron
and nickel.
The outer core
The solid centre of the Earth.
The inner core.
The reason why digging or
drilling to the centre of the Earth
is impossible?
It is WAY TOO HOT! Also,
there is too much pressure.
The name of the first guy to
hypothesis Plate Tectonics?
Alfred Wegener
The name of the first
supercontinent
Pangaea
Wegener used these leftovers
from plants and animals to
support his theory.
Fossils
Wegener also thought these,
including mountains and coal
deposits, supported his theory.
Landforms
Though Wegener thought of his
theory in the 1920’s, the idea
wasn’t widely accepted until this
in the 1960’s.
New technology led to the
discovery of sea-floor spreading
and mid-ocean ridges.
There are two different forms of
crust on Earth.
Heavy and dense OCEANIC
crust (mostly basalt) and lighter
CONTINENTAL crust (mostly
granite).
Plates due to this movement in
the mantle.
Convection currents
Where plate boundaries come
together two things can happen.
Convergent boundaries: can
result in a subduction zone
(when one plate is oceanic and
sinks below a continental plate)
or create large mountain ranges
(when two continental plates
collide)
When to plates move away from
each other, it is known as this.
Divergent Boundary
Two plates moving along each
other, but in opposite directions
causes this type of fault.
Transform fault
The sudden release of energy
caused by the movement of
plates.
An earthquake.
Small earthquakes constantly
take place at these boundaries
where new crust is being formed
as plates move apart.
Divergent boundary (like at the
Mid-Ocean Ridge)
The earthquakes we feel in
Victoria are caused by the
release of energy from this type
of plate boundary.
Convergent boundaries
A large, sometimes destructive,
wave generated by an
underwater earthquake.
Tsunamis
The three types of seismic
waves.
P, S, and Surface Waves
The name for any opening in the
Earth’s crust through which
molten rock and other materials
erupt.
A volcano.
Young and active volcanoes, that
often erupt underwater are
common at these plate
boundaries.
Divergent plate boundaries.
Highly explosive, large
volcanoes that release steam, ash
and lava are common at these
plate boundaries.
Convergent plate boundaries
where there is a subduction
zone.
Volcanoes that form in places
that are NOT plate boundaries
form at these.
Hotspots
British Columbia has these kinds
of volcanoes.
Convergent, divergent and
hotspot.
