Rank the four main layers
of the earth from least
dense to most dense.

What causes the plate
tectonics to move?
Earthquake Map
Divergent Boundary
•
Where two plates are moving apart
•
Land feature formed: mid-ocean ridges (by sea - floor
spreading)
•
Rift occurs when two continental plates pull apart
•
New crust forms because magma pushes up and
hardens between separating plates. Creates new
crust.
Convergent Boundary - Oceanic and Oceanic
Collide (O-O)
•
When Two Oceanic plates collide.
•
Creates Subduction Zone and Volcanic Arc Destroys some crust
Convergent Boundary - Continental and
Oceanic Collide (C-O)
•
An Oceanic and Continental Plate Collide
•
Creates Subduction Zone - Destroys some crust
Convergent Boundary - Continental and
Continental Collide (C-C)
•
Two plates come together and collide
•
Creates Folded Mountains
Transform Fault Boundary
•
Where two plates slide past each other.
•
Crust is neither created nor destroyed
•
Earthquakes occur frequently along this type of
boundary.
Examples:
•
The San Andreas Fault is a
transform fault boundary and
has been the site of many
earthquakes.
