Describe the
different types of
plate boundaries
Addie and Alex have an assignment about Plate Boundaries, they
will research their assignment in their phone App which is “Science
Adventure”
The Science Adventure App alerted Gene a “malfunction emoji” and his
friends Jailbreak and Hi-5.
Gene! Science Adventure
has alerted us
Oh, really? Maybe Alex and
Addie have an assignment.
Let’s help them!!!
Oh, No!! I
hope there’s
no bot in that
App
The friends decided to go to Science Adventure App to help Alex and
Addie.
What are plate boundaries?
Plate tectonics constantly move around the
planet.
The border between two tectonic plates is
called Boundary.
Different Movement of plates boundaries:
1. Moving toward each other
2. Moving apart from each other
3. Sliding past each other
What are the
different kinds of
plate boundaries?
Convergent boundary
Transform-fault Boundary
Divergent Boundary
What is
convergence
boundary?
Convergent Boundary
- Where plates move towards each
other
Three types of Convergent boundary:
Oceanic- continental convergence
Oceanic-oceanic convergence
Continental- continental convergence
Oceanic- continental Convergence
It is a collision of
continental and
oceanic crust,
where subduction
process happens.
Subduction
happens when
denser crust
(Oceanic) sinks
towards the mantle
Volcanic Arc
Trench
Subduction causes the magma to rise causing
the formation of geological features like
volcanic arc and trenches
The geological event that might happen is
earthquake
Oceanic- Oceanic Convergence
It is a collision of
oceanic and oceanic
crust, where
subduction process
also happens.
Forming geological
features like
trenches that is
parallel to
volcanic island arc
The geological
events that
could happen
is earthquake
and tsunamis
Many parts of
the Philippines
originated
from oceanicoceanic
convergence
Continental-Continental Convergence
When two
continental plates
converge, collision
zone is from. No
subduction process
happened, the
pressure is released
by pushing the
crusts upward
No trenches, volcano
and no island arc.
Geological feature
that can be only
form is mountains
Geological event
that
can
happen
Himalayas Peak is the
during
the
collision
product of continental is
shallow
continental
earthquake
convergence
So, mountains, volcano and
trenches are products of
convergent boundary, how
about the divergent
boundary?
Divergent Boundary
- Where plates moves away from
each other
As the Plates separate, underwater
mountain ranges is formed which is called
ocean ridges. Rocks on ocean ridges are
cooled molten material formed from the
mantle as it ooze up and fill the gap. It
spread 2 to 20 cm per year
Mid Atlantic
Ridge is an
example of
ocean ridge
which causes
the divergence
between the
South American
Plate and
African Plate
While splitting of plates on the crust
causes the formation of rift valley
Ahh, the marks under the
ocean is due to divergent
boundary. What about the
last type of boundary?
Transform Fault Boundary
- Where plates slide past each other
Transform faults join two segments of
mid oceanic ridges
Mid-oceanic
ridge
Mid-oceanic
ridge
Geological
Feature that
can be formed
is fault line
Geological
event that
might happen
San Andreas Fault is one of is earth quake
the most active fault lines
in the world
So, fault system is a product
of transform fault boundary
But , how about the
Hawaiian Island I heard
there is no boundaries there
but the volcanoes are every
where
Hawaiian Islands
This island is
located at the
center of the
ring of fire,
but there is
no plate
boundaries
there.
Hawaiian Island was created by the
an intraplate activity
(Hot Spot volcanism) which describes
volcanic activity that occurs within
tectonic plates and is generally NOT
related to plate boundaries.
The molten material is coming out in
the hot spot is from the mantle
called magma/mantle plume.
As the plate
moves, older
volcano move
from the source of
magma and
eventually dies,
but new volcano
will be formed on
the hot spot
That’s how plate
boundaries give
rise to geological
feature and
events
Let’s test what you have
