MARIANAS /JAPAN TRENCH
The Marianas/Japan Trench is a converging
plate-subduction- boundary that is oceanic to
oceanic.
 The Pacific plate (ocean) is sub ducted
underneath the Mariana/Philippine Plate
(ocean)

JAPAN
A subduction zone – ocean to ocean (or
continent debate)
 The Pacific plate sub ducts into the Eurasian

HAWAII ISLANDS
Molten Magma breaks through crustal plate to
create these islands
 Created from a “hot spot”
 Plate involved is the Pacific Plate

PACIFIC N.W, CASCADE VOLCANOES
Convergent plate boundary by an oceanic
and continental plate
 Part of the Pacific Ring of Fire
 The Juan de Fuca subducts underneath the
North American Plate

SAN ANDREAS FAULT
A continental and oceanic transform plate
boundary (slides past each other)
 The Pacific Plate and the North American Plate
are involved

PERU-CHILE TRENCH

A converging plate boundary that is created
by the Nazca Plate subducting under the South
American Plate
MID ATLANTIC RIDGE, ICELAND
Divergence
 Boundary between plates where new oceanic crust is being created on the
floor of the Atlantic Ocean. It marks the boundary between the Eurasian
Plate and the North American Plate and it separates the African Plate from
the South American Plate.

AFRICAN RIFT VALLEY
A diverging (continent moving away from
continent)plate boundary
 The Arabian and African plates

HIMALAYAN MOUNTAINS
Continent to Continent plate – COMPRESIION
(FOLD MOUNTAINS just LIKE Rockies and in
Europe the ALPS)
 Eurasian and Indian Plate involved
 Indian plate pushing up against Eurasian plate

ALEUTIAN ISLANDS
A convergent subducting (ocean to ocean)
plate boundary
 The Pacific Plate subducts the North American
Plate

JAVA TRENCH
Converging plate boundary
 Indo-Australian (oceanic) is subducting beneath
the Eurasian plate (oceanic)
