3  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

6 Japan

7  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)

8  The trench is deep enough that Mt. Everest could fit in its place

13  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

17  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.

18  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

19

20  The ridge played an important in the break up of Pangaea

23  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

26  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 Cascade Volcanoes' North America British Colombia Washington Oregon Northern California

27

28  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

31  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

32  Transformation- fault boundary  2 plates are sliding horizontally past one another.  Usually appear in ocean floors but a few occur on land such as California
