Aim: How do the different types
of plate boundaries differ?
Do Now:
Name the three different types of
plate boundaries. (Use the pictures
to help you name them.)
Box #1:
Convergent zone
Convergent zone
• Occurs when 2 plates collide.
Example 1. Continental-Continental: When two
continental plate collide mountains are formed.
Continental-Continental convergent
zones
Example 2.
Subduction Boundaries: Ocean plate goes under
less dense plate.
• Deep focus quakes.
• Trenches
• Volcanic island
Mariana’s Trench
• The Mariana Trench is located in the Pacific
Ocean, just east of the 14 Mariana Islands
near Japan.
• It is the deepest part of the earth's oceans,
and the deepest location of the earth itself.
• It was created by ocean-to-ocean subduction.
Food for thought……
If mount Everest reaches an altitude of 29,035‘
above sea level…..
And the Mariana’s trench is 36,201’
If we had the ability to take Mount Everest and
turn it upside down and place it in the Mariana
trench….Would it fit?
YES
With 7,166 feet of water above it!!! WOW
That’s 1.3 miles from Hicksville high school to
northern state parkway!!!
Box #2
• Divergent Zones (Di means to break into 2)
• Divergent zones have 2 plates are moving
apart, spreading at the center
• A. Mid-Ocean Ridges. (most are these types)
Example: Iceland.
• B. Continental Rifting: Magma rises forming a
rift and eventually forms a sea.

3rd Box
Transform fault
• A transform fault is a plate boundary that
slides past one another.
• Example:
San Andréa's fault, California
Take out a piece of paper…
Put your name, period and date on it..
The students who gets this question correct will
receive 3 extra points on their next quiz….
How many tectonic plates
does the Earth contain?
