 What is an Oceanic Trench?
◦ Oceanic trenches are topographic depressions of the sea
floor, relatively narrow in width, but very long.
◦ These oceanographic features are the deepest parts of the
ocean floor.
◦ These are the distinctive features of the convergent plate
boundaries.
◦ Oceanic lithosphere moves into trenches at a global rate of
about 3 km2/yr.

 The Mariana Trench is the deepest part of the world's oceans.
 Pacific plate subducting beneath Philippine sea plate
 It is located in the western Pacific Ocean, an average of 124
miles or 200km to the east of the Mariana Islands, Philippines.
 The trench is about 2,550 kilometers (1,580 mi) long with an
average width of 69 kilometers (43 mi).
 It is a crescent-shaped scar in the Earth's crust.
 Its maximum depth is 11,034 m(36,201 ft).

 The Tonga Trench is an oceanic trench located in the south-
west Pacific Ocean.
 It is the deepest trench of the Southern Hemisphere and the
second deepest on Earth.
 The Tonga Trench is the northern half of the Tonga-Kermadec
subduction system which extends 2,550 km (1,580 mi)
between New Zeeland and Tonga.
 The maximum depth of Tonga Trench is 10,882 m (35,702 ft).

 The Philippine Trench (also Philippine Deep, Mindanao
Trench, and Mindanao Deep) is a submarine trench to the east
of the Philippines.
 Philippine sea plate subduct beneath Philippine mobile belt
 It has a length of approximately 1,320 kilometers (820 miles)
and a width of about 30 km (19 mi) from the center of the
Philippine island of Luzon.
 The maximum depth of Philippine Trench is 10,545 m
(34,596 ft).
Major oceanic trenches
 The Kuril–Kamchatka Trench or Kuril Trench is an oceanic trench in
the northwest Pacific Ocean.
 It extends from a triple junction with the Ulakhan Fault and
the Aleutian Trench near the Commander Islands, Russia, in the
northeast, to the intersection with the Japan Trench in the southwest.
 The trench formed as a result of the subduction zone, which formed in
the late Cretaceous, that created the Kuril island arc as well as the
Kamchatka volcanic arc.
 Its maximum depth is 10,542 m (34,587 ft).
