The deepest point on the earth is dash in the pacific ocean

The deepest point in the sea is the Challenger Deep, located beneath the Pacific Ocean about 300 km (186 mi) southwest of Guam. According to measurements made in October 2010 by the US Navy survey ship USNS Sumner, the bottom of the Challenger Deep lies 10,994 m (36,070 ft) below sea level. Other surveys have measured roughly similar depths, with figures varying from 10,900 m (35,760 ft) (measured as part of the British Challenger II expedition in 1951) to 11,034 (36,201 ft) (measured by the Soviet research ship Vityaz in 1957). The Challenger Deep forms part of a large fault in the ocean floor called the Mariana Trench and was first discovered by the HMS Challenger – for which the feature is named – on 23 March 1875. The original depth soundings – done by lowering a weighted line into the sea – resulted in an estimated depth of 8,184 m (26,850 ft / 4,475 fathoms), which has been consistently revised down as measuring methods improve. Confusingly, the Royal Navy has had 8 ships called Challenger over the last 200 years, three of which were survey ships. Records change on a daily basis and are not immediately published online.

Point Nemo is the most remote place on Earth - the place farthest from land. It is locatedin the South Pacific Ocean and lies around 2,688 kilometers(1,670 miles) from the nearest land. It is called “Point Nemo” because “nemo” means “no one” in Latin. It is also the name of Twenty Thousand Leagues Under the Seas (1870) and The Mysterious Island (1875). Point Nemo is not only the middle of nowhere, it is also a spacecraft graveyard: the place where NASA and other space agencies crash their de-orbited satellites, Facts about Point Nemo 1. The oceanic pole of inaccessibility Point Nemo is also referred to as the oceanic pole of inaccessibility. This means that it is the place on the ocean that is furthest away from any land. A pole of inaccessibility refers to a place on Earth that is the most inaccessible to reach according to set criteria. On land, it often refers to the point that is farthest from the coastline. Poles of inaccessibility include: • The Northern pole of inaccessibility is located in the Arctic Ocean pack ice. This lies at85°48′N 176°9′W, about 626 miles (1,008 kilometers) from the nearest landmasses of Ellesmere Island (in Canada), Henrietta Island (in the East Siberian Sea), and Arctic Cape (in the Russian High Arctic). • The Southern pole of inaccessibility commonly refers to a location in a (former) Soviet Union research station in Antarctica, about 546 miles (878 kilometers) from the Terrestrial South Pole. • The Continental poles of inaccessibility: a p...

Mariana Trench The deepest point on the earth is Mariana Trench in the Pacific Ocean. More information: The deepest point ever recorded on the Earth is Mariana Trench (also known as Marianas Trench). It is situated between Guam and the Philippines in the western Pacific Ocean. It has shape of like- crescent type. It depth is around 11,034 meters. It deepest point is know as 'Challenger Depth'.

Ocean trenches are long, narrow depressions on the seafloor. These chasms are the deepest parts of the ocean—and some of the deepest natural spots on Earth. Ocean trenches are found in every ocean basin on the planet, although the deepest ocean trenches ring the Pacific as part of the so-cal led “ Ring of Fire” that also includes active volcanoes and earthquake zones. Ocean trenches are a result of tectonic activity, which describes the movement of the Earth’s lithosphere. In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plates meet. At many convergent plate boundaries, denselitho sphere melts or slides beneath less-denselithosphere in a process called subduction, creating a trench. Ocean trenches occupy the deepest layer of the ocean, the hadalpelagic zone. The intense pressure, lack of sunlight, and frigid temperatures of the hadalpelagic zone make ocean trenches some of the most unique habitats on Earth. How Ocean Trenches Form Subduction ZonesWhen the leading edge of a densetectonic plate meets the leading edge of a less-dense plate, the denser plate bends downward. This place where the denser plate subducts is called a subduction zone. Oceanic subduction zones almost always feature a small hill preceding the ocean trench itself. This hill, called the outer trench swell, marks the region where the subducting plate begins to buckle and fall beneath the more buoyant plate. Some ocean trenches are formed by subduction ...

1. Build background on the deepest place on Earth. Have a whole-class discussion. Ask: • What is the highest point in the world and where is it located? (Mount Everest at approximately 8,850 meters, or 29,035 feet; located on the borders of Nepal and China) • What is the deepest location on Earth and where is it located? Elicit student responses. Then explain to students that the Mariana Trench is the deepest part of the ocean and the deepest location on Earth. It is 11,034 meters (36,201 feet) deep, which is almost 7 miles. Tell students that if you placed Mount Everest at the bottom of the 2. Have students locate the Mariana Trench on a map. Show students the NG Education interactive map and invite a volunteer to pinpoint the location of the Mariana Trench, which is just to the east of the Mariana Islands. Ask: The Trench is in what ocean? (the Pacific Ocean) Have students note the nearest bodies of land—Guam and the Mariana Islands. Tell students that the Trench is 2,500 kilometers (1,554 miles) long and 70 kilometers (44 miles) wide. 3. Discuss who has jurisdiction over the Mariana Trench. Review the concept of jurisdiction. Tell students that jurisdiction is the power or right to exercise authority. Have students look at the location of the Trench again. Ask: Who do you think has jurisdiction over, and therefore responsibility for, the resources of the Mariana Trench? Explain to students that according to the 4. Have students identify how researchers can access the Tr...

It’s a known fact that the oceans do not have even terrains and there are some points which are deeper than others. The deepest region of the earth’s ocean is the Challenger Deep. Situated on the floor of the Pacific Ocean, this is a valley on the southern part of the Mariana Trench. Mariana Trench is a 43mi broad crescent-shaped region on the floor of the Pacific Ocean. The Challenger Deep has a depth of approximately 36,070ft (with an error of +/-130ft). Mariana Trench The Mariana Trench is situated at the boundary of two converging plates, where two oceanic lithosphere plates collided resulting in one of them descending into the Earth’s mantle. Ocean trenches form some of the most profound valleys on the ocean. An ocean trench is a downward flexure that is formed at the boundary where two lithosphere plates collided. The Marianas Trench was first measured by a British survey ship known as HMS Challenger in 1875 and the highest depth measured was 26,850ft. In 1951, a second HMS Challenger discovered a deeper point on the Marianas Trench using the echo-sounding technique, which was approximately 35,760ft deeper. In 2009, researchers on RV Kilo Moana doing sonar mapping determined that it was 35,994ft deep with a 72ft error. The most recent measure by the Coastal and Ocean mapping center of the United States in 2010 concluded that the Challenger Deep is 36,070ft deep with a potential error of 130ft. Exploring the Challenger Deep Don Walsh and Jacques Piccard were the first...

The crescent-shaped trench is in the Western Pacific, just east of the Mariana Islands near Guam. The region surrounding the trench is noteworthy for many unique environments, including vents bubbling up liquid sulfur and carbon dioxide, active mud volcanoes and marine life adapted to pressures 1,000 times that at sea level. The Challenger Deep, in the southern end of the Mariana Trench (sometimes called the Marianas Trench), is the deepest spot in the ocean. Its depth is difficult to measure from the surface, but in 2010, the National Oceanic and Atmospheric Administration used sound pulses sent through the ocean and pegged the Challenger Deep d at 36,070 feet (10,994 meters). A 2021 estimate using pressure sensors found the deepest spot in Challenger Deep was 35,876 feet (10,935 m). Other modern estimates vary by less than 1,000 feet (305 m). Who owns the Mariana Trench? The Mariana Trench is 1,580 miles (2,542 km) long — more than five times the length of the Grand Canyon. However, the narrow trench averages only 43 miles (69 km) wide. Because Guam is a United States territory and the 15 Northern Mariana Islands are governed by a U.S. Commonwealth, the U.S. has jurisdiction over the Mariana Trench. In 2009, former President George W. Bush established the Mariana Trench Marine National Monument, which created a protected marine reserve for the approximately 195,000 square miles (506,000 square km) of seafloor and waters surrounding the remote islands. The monument includ...
