Describe the Process of Subduction at a Deep Ocean Trench

A region where this process occurs is known as a subduction. Then the oceanic crust sinks back into the mantle through a process called subduction.

There it sinks under lighter crust.

. The process shown in this diagram is. It returns to molten rock becoming part of the mantle again. When the oceanic plate is forced below the continental plate it melts to form magma and earthquakes are triggered.

A subduction zone and its occurrence can be traced from the formation of mid-ocean ridges. This trench was created as a result of the subduction of the oceanic Plateau plate beneath the continental Okhotsk plane. The deep trench was created due to the bending of the plate which was going down.

Deep-sea trench also called oceanic trench any long narrow steep-sided depression in the ocean bottom in which occur the maximum oceanic depths approximately 7300 to more than 11000 metres 24000 to 36000 feet. They typically form in locations where one tectonic plate subducts under another. Philippine Trench also called Philippine Deep Mindanao Trench or Mindanao Deep is a submarine trench in the floor of the Philippine Sea of the western North Pacific Ocean bordering the east coast of the island of Mindanao.

Oceanic subduction zones almost always feature a small hill preceding the ocean trench itself. Ocean trenches are driven by. Whats an ocean trench.

Results from a survey of the seafloor off the European coast reveal the depths our garbage can reach. The explanation of subduction perhaps makes the process sound relatively smooth with one plate slowly sinking and falling off into the mantle layer below. Water and land meet.

Molten material rises from the mantle and erupts through the mid-ocean ridge. First of all subduction causes deep ocean trenches. At some points the oceanic crust bends downward and forms a deep-ocean trench.

The lava spreads out pushing older rocks aside. When the leading edge of a dense tectonic plate meets the leading edge of a less-dense plate the denser plate bends downward. The process by which the Earths crust is destroyed is called subduction and it most commonly occurs at the deep ocean regions of the world where ocean trenches are formed.

The Puerto Rico Trench is the deepest in Atlantic Ocean. It is home to the Challenger Deep which at 10911 meters 35797 feet is the deepest part of the ocean. Bottles plastic bags fishing gear and various crap have been found as deep 45 kilometers.

Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate the heavier plate dives beneath the second plate and sinks into the mantle. Deepest point - Milwaukee Deep The Puerto Rico Trench is located on the boundary between the Caribbean Sea and the Atlantic Ocean. The deepest trench in the world the Mariana Trench located near the Mariana Islands is 1580 miles long and averages just 43 miles wide.

Through the process of subduction old dense crust is pushed toward a deep-ocean trench. Subduction accounts for the geophysical process where one of the tectonic plates on the Earths surface slides beneath the other. In subduction one tectonic plate a large portion of the Earths crust slides under another.

These mid-ocean ridges are a range of volcanic hills found underwater. The oceanic trench is associated with a complex transition between the Lesser Antilles subduction. Subduction allows part of the ocean floor to sink back into the mantle over tens of millions of.

The oceanic crust on the plate sinks back to the mantle at. The point at which this happens is called the subduction zone. Usually one of the converging plates will move beneath the other a process known as subduction.

Look at the diagram and then answer the following questions. There it sinks under lighter crust. Subduction is a powerful process that changes the shape of continents recycles plate material to create new rock builds volcanoes and ocean trenches causes earthquakes and generates tsunamis.

Lithosphere layer below the ocean goes below land. The abyss which reaches the second greatest depth known in any ocean was first. The process by which the ocean floor sinks beneath continental crust at a deep-ocean trench and back into the mantle is known as.

A deep ocean trench with parts A through D labeled. Describe the process of sea-floor spreading. Subduction happens when two convergent boundries come together and 1 slides under the other causing a deep ocean trench.

The Tonga Kuril-Kamatcha Philippine and Kermadec Trenches all contain depths greater than 10000. Lithosphere layer below land stops at lithosphere layer below ocean. Ocean trenches are long steep-sided depressions on the ocean floor extending for thousands of miles in length and as little as a few miles across.

At a subduction zone a plate forms a trench as it sinks under the other plate. Deep trenches are features often formed where tectonic plates are. Most scientists however describe subduction as a rough scraping activity that is characterized by high amounts of friction as the two plates rub past each other.

Deep ocean trenches are formed during a process known as subduction. Describe the process of subduction at a deep-ocean trench. At its deepest point the trench lies at 9000 m under the sea making it one of the deepest trenches on the entire planet.

Subduction is a geological process in which the oceanic lithosphere is recycled into the Earths mantle at convergent boundaries. If two tectonic plates collide they form a convergent plate boundary. This place where the denser plate subducts is called a subduction zone.
