Slip, Slide and Collide
How Do Tectonic Plates Move?
3 Types of Plate
Boundaries
(1) Divergent (constructive)
Convergent (destructive)
Transform (conservative)

Divergent = Constructive
(2)Divergent plates separate and new crust is
formed to fill in the gap left by the two
divergent plates.
Where are Divergent
Plate Boundaries?
(3)Mid Atlantic Ridge- runs
along the Atlantic Ocean
between the Americas and
Africa/Europe.
(They are getting farther apart
every year!)
(4) Draw a constructive
Divergent Plate Boundary.

Transform= Conservative
(5) Transform Plates
move past one
another, sliding.
They do not destroy
or create land.
Where are
Transform Plate
Boundaries?
(6) San Andres
Fault in
California.
(7) When the
plates move
past one
another they
create
earthquakes.
(8)Draw a conservative
Transform Plate Boundary.

Collide Convergent Plate Boundary
(destructive)
Convergent Plates animation
Convergent = Destructive
(9) Subduction- the process by which two
plates collide and one plate is drawn
underneath the other.
The Older Plate
normally goes
underneath the
younger plate
because it is
heavier.
Convergent Plates and Subduction
(10) Convergent Plates are destroyed when
one goes underneath the other.
Convergent Plate Boundary
Convergent can either be
(11)
• continental-oceanic,
• oceanic-oceanic
• continental-continental
Where are Continental –
Continental Plate Boundaries?
The Himalayas in India. The two plates
collided and pushed one plate up to create
the mountains.
Where are Oceanic- Oceanic Plate
Boundaries?
Mariana Trench
• off the coast of Japan and the
Philippines.
Islands
• Underwater volcanoes form new
land masses
Where are Oceanic- Continental
Plate Boundaries?
Volcanoes- found all along the “Ring of Fire”
where active volcanoes are found because of
subducting plates melting and becoming magma
for volcanoes.
(12) Draw a destructive
Convergent Plate Boundary.

In 50 Million years, scientist believe that the world
will look like this!
