- Marine Zone: are divisions of the ocean. Oceanographers divide the ocean into two basic parts; the pelagic or open ocean, and the benthic or sea floor. The pelagic is divided into five broad zones according to how far down sunlight penetrates:ote: The word kai refers to the ocean and all its parts. Unlike the science point of view where the divisions of the ocean are due to the penetration of light, the Hawaiians division of the ocean depended on the life forms in the depths of the ocean.

The Earth's Layers Lesson #1 Because of this the continents ride on the denser oceanic plates. The crust and the upper layer of the mantle together make up a zone of rigid, brittle rock called the Lithosphere. The layer below the rigid lithosphere is a zone of asphalt-like consistancy called the Asthenosphere. The asthenosphere is the part of the mantle that flows and moves the plates of the Earth.

Layers of the Ocean Epipelagic Zone- The surface layer of the ocean is known as the epipelagic zone and extends from the surface to 200 meters (656 feet). It is also known as the sunlight zone because this is where most of the visible light exists. With the light come heat. This heat is responsible for the wide range of temperatures that occur in this zone.

- Stable subduction zones involve the oceanic lithosphere of one plate sliding beneath the continental lithosphere or oceanic lithosphere of another plate due to the higher density of the oceanic lithosphere. That is, the subducted lithosphere is always oceanic while the over-riding lithosphere may or may not be oceanic. Subduction zones are sites of high rates of volcanism, earthquakes, and mountain building.

Oceanic Crust: Definition, Composition & Facts Oceanic crust is the part of the Earth's crust that makes up the seafloor. It's thinner, denser, and simpler in structure than the continental crust. Oceanic crust is also younger, on average; from its birth at a mid-ocean ridge to its end at a subduction zone is no more than 250 million years.ragments of the oceanic crust sometimes become stranded high and dry on top of a continent due to uplift. It is partly thanks to these ancient ophiolites that we understand as much as we do about the composition of this layer of the Earth's lithosphere.

- The process by which the oceanic crust is pulled under the continental crust is called subduction and the zone at which this occurs at the plate boundaries is called the subduction zone. At the subduction zone where the oceanic crust sinks beneath the continental crust a deep oceanic trench or valley is created.These can be many of thousands of kilometres long and 8 to 10 kilometres deep making them the deepest part of the ocean floor.t the subduction zone where the oceanic crust sinks beneath the continental crust a deep oceanic trench or valley is created.

- At a compressional or destructive boundary the plates are moving towards each other. This usually involves a continental plate and an oceanic plate. The oceanic plate is denser than the continental plate so, as they move together, the oceanic plate is forced underneath the continental plate.The point at which this happens is called the subduction zone.As the oceanic plate is forced below the continental plate it melts to form magma and earthquakes are triggered. The magma collects to form a magma chamber [magma chamber: A region under the surface of the Earth where hot molten magma collects. ] .This magma then rises up through cracks in the continental crust.his usually involves a continental plate and an oceanic plate. The oceanic plate is denser than the continental plate so, as they move together, the oceanic plate is forced underneath the continental plate.

Hadal zone: Ten things you never knew about the ocean's deepest places We scientists like to categorise things and the ocean depths are no exception. Depths from the surface to 0.2km is known as the littoral zone, from 0.2km to 3km, the bathyal zone, and from 3km to 6km, the abyssal zone. Anything deeper than that is the hadal zone. The hadal zone is largely comprised of deep trenches caused by tectonic plate subduction that drive the vast abyssal plains steeply down to depths of 11,000 metres in places.

What Is a Subduction Zone? Oceanic crust is denser than continental crust. At a subduction zone, the oceanic crust usually sinks into the mantle beneath lighter continental crust. If the same kind of crust collides, such as continent-continent, the plates may crash together without subducting and crumple together like crashing cars.

Oceanic trench Oceanic crust is formed at an oceanic ridge, while the lithosphere is subducted back into the asthenosphere at trenches. The oceanic trenches are hemispheric-scale long but narrow topographic depressions of the sea floor. They are also the deepest parts of the ocean floor.Oceanic trenches are a distinctive morphological feature of convergent plate boundaries, along which lithospheric plates move towards each other at rates that vary from a few mm to over ten cm per year.he greatest ocean depth to be sounded is in the Challenger Deep of the Mariana Trench, at a depth of 11,034 m (36,201 ft) below sea level.

Ocean Trenches Mariana Trench Trenches form in some areas when two oceanic plates converge forming a subduction zone. The Pacific Plate is subducting beneath the Mariana Plate forming Mariana Trench. The Pacific Plate is older and colder than the Mariana Plate.cean Trenches. Introduction. Ocean trenches are natural tectonic plate boundaries between two crustal plates. When a continental plate converges with an oceanic plate a subduction zone forms. The heavier oceanic plate subducts beneath the lighter continental plate forming a trench.

Earths Layers The Earths layers inside our planet are divided into three major areas. The areas are the lithosphere, mantle and core. Research carried out by seismologists since this original division have further divided the Earths layers based on the type of rock and speed earthquake waves travel through them.ithosphere. The lithosphere includes the crust and part of the upper mantle. This layer contains rigid rocks that move around the Earth about the speed our fingernails grow. The crustal plates as they move apart form divergent boundaries.
