OCEAN FLOOR ADVENTURE
By:
Aaron ChuDaniel Johnson
Japan
Europe
Iceland California
TRENCH Trench: A cut in the ground
Can be up to 7300 or more meters deep
Typically form in locations where tectonic plates subduct under another
Parallel to adjacent island arcs or mountain ranges of the continental margins
Closely associated with and found in subduction zones
OUR ADVENTURE
BEGINS!
DAY 1
MARIANA TRENCH
Japan
Deepest part of the earth 11,000 meters deep
Formed by ocean-to-ocean subduction 1 plate (piece of
lithosphere) moves underneath another
Located in the Pacific Ocean East of the 14 Mariana
Islands 11"21' North latitude and 142"
12' East longitude (near Japan)
The trench is deep enough that Mt. Everest could fit in its place
Jellyfish
Football Fish
Scary Dragonfish
DAY 2
IZU BONIN-MARIANA ARC
Japan
IZU-BONIN-MARIANA ARC
IZU-BONIN-MARIANA ARC Volcanic island arc
2800 km south from Tokyo 1100 km long and 300 to 400 km wide
Contains Izu Islands , Bonin Islands, and Mariana Islands
Convergent boundary Crust is destroyed and recycled back into the interior of the Earth
as one plate dives under another Often known as “Subduction zones”
Formed as a result of subduction of the western Pacific plate
TO ICELAND!
DAY 3
ICELAND
Japan Europe Iceland
ICELAND DIVERGENT PLATE Mid-Atlantic Ridge
runs beneath Iceland North American Plate
moves west, while the Eurasian Plate moves east
Iceland is slowly being split in 2 pieces
Result of this is divergent boundary New crust is created as
2 or more plates pull away from each other.
MID-OCEAN RIDGE Mid-Ocean ridge
Underwater mountain range, formed by plate tectonics
Seafloor spreading occurs during this process Process in which the ocean
floor is extended when two playes move apart.
Mid-Atlantic Ridge includes a deep rift valley Runs along the axis of the
ridge along nearly its entire length
Mid-Atlantic ridge
65,000 kilometers
Between 22° and 23°N and 44°30′ to 46°20′W
Formed by the movement of the Earth's tectonic plates.
The ridge played an important in the break up of Pangaea

PALEOMAGNETISM
Paleomagnetism Study of the record of the Earth’s magnetic
field in rocks.
• Paleomagnetists study the Paleomagnetic stripes in the mid ocean ridge to see the.. Iron rich basaltic lava erupted along mid-
ocean ridges
Iron within the basalt is permanently oriented by the magnetic field of the Earth
DAY 4
CALIFORNIA
Japan Europe Iceland
California
CASCADE VOLCANOES' Cascade Volcanoes
Extends about 1,100 km
Formed due to subduction along the Cascadia subduction zone
Series of volcanoes in North America
Extends from southwestern British Colombia through Washington and Oregon to Northern California

North America
British Colombia
Washington
Oregon
Northern California
VOLCANIC ARC Cascade Volcanoes' = Volcanic arc’s
Volcanic Arc Chain of volcanoes positioned in an arc
2 types Oceanic arcs : forms when oceanic crust subducts
beneath another oceanic crust
Continental arcs: forms when oceanic crust subducts beneath continental, creating an arc-shaped mountain belt
SAN ANDREAS SHORT FILM
http://www.youtube.com/watch?v=IKmJEVZDI6c
SAN ANDREAS FAULT In California lays the
San Andreas fault 800 mi. long Tectonic boundary
between the Pacific plate and the North Atlantic plate
35°07'N, 119°39'W
The fault is a transformation fault boundary
TRANSFORMATION-FAULT BOUNDARY
Transformation-fault boundary2 plates are
sliding horizontally past one another.
Usually appear in ocean floors but a few occur on land such as California
