When a piece of the ocean floor cracks, one side of the crack will sink beneath the other side. As it sinks, it pulls the rest of its plate with it. The sinking sea floor grinds against the other side of the crack and tears parts off. The result is a long, deep trench. This process is how the Mariana Trench formed.

What type of rock is the Mariana trench made out of?
The Mariana Trench, the deepest part of the world's oceans, primarily consists of sedimentary rocks and oceanic crust, which is mainly basalt. The trench is formed by the subduction of the Pacific Plate beneath the Mariana Plate, leading to the creation of various geological features, including abyssal plains and deep-sea sediments. Additionally, the trench contains sediments that have accumulated over time, including organic material and minerals.
What kind of plate was the marianas trench made on?
The Mariana Trench is on two tectonic plates: The Pacific Plate and the Mariana Plate. The Pacific Plate is beneath the Mariana Plate by subduction.
What are the key differences between the Kola Superdeep Borehole and the Mariana Trench?
The Kola Superdeep Borehole is a man-made hole drilled into the Earth's crust, reaching a depth of about 7.5 miles. The Mariana Trench is a natural trench in the ocean floor, known as the deepest point on Earth, reaching a depth of about 36,000 feet. The main difference is that the Kola Superdeep Borehole is on land and drilled by humans, while the Mariana Trench is underwater and formed by natural geological processes.
Why is Jacques piccard important?
he was important because him and don walsh made it down to the mariana trench no human had been before.
The Mariana Trench - Last Exploration with man crew submarine?
In January 1960, Jacques Piccard and Lt. Don Walsh of the US Navy made the descent in the submarine Trieste to the floor of the Mariana trough
How long did James Cameron go in the mariana trench?
James Cameron descended to the Mariana Trench on March 26, 2012, in a submersible named Deepsea Challenger. He reached a depth of about 10,908 meters (35,787 feet) and spent approximately three hours exploring the trench floor. This historic dive made him the first person to reach the deepest part of the ocean solo.
How was the depth of the mariana trench measured?
The Mariana Trench was first measured by HMS Challenger in 1875 using sounding lines. The depth recorded by that method was 4,475 fathoms (8,184m). The first sonar measurement was made by another oceanographic survey ship of the same name, in 1951. The depth reported by that expedition was 10,911 meters.
What physical geographic features made invading Iwo Jima Difficult?
The physical geographic features that made invading of Lwo Jima difficult are Mount Suribachi, Ogasawara Islands,and Mariana Islands.
The deepest hole in the world naturally made?
Mariana Trench In Pacific Ocean, 36,200 ft deep.Deepest cave is Voronya Cave in Abkhazia, Georgia (European, not American which is 7,190 ft deep.
Why is the deepest part of the Mariana trench call challengers deep?
The deepest part of the Mariana Trench is called Challenger Deep in honor of the HMS Challenger expedition, which took place from 1872 to 1876. During this scientific voyage, researchers conducted significant oceanographic studies and made the first measurements of ocean depths. The name reflects the expedition's pioneering role in deep-sea exploration and its contributions to our understanding of the ocean's depths.
How thin is the earth's crust at the mariana trench?
The surface of the earth is made up of two layers:- the oceanic crust and the continental crust. The oceanic crust is between 6-10km in thickness while the continental crust may be up to 70 km thick. by SVM
Who invented the trench coat?
The trench coat was made as an alternative to the great coat worn by French and British soldiers in WW1. Thomas Burberry made the first trench coat in 1920.
