Slip, Slide and Collide

How Do Tectonic Plates Move?

3 Types of Plate Boundaries

(1) Divergent (constructive)

Convergent (destructive)

Transform (conservative)

Slip Divergent Plate Boundary(Constructive)

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 = 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 BoundaryConvergent 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.

will look like this!
