ocean floor adventure

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

British Colombia

Washington

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

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
