When we talk about the deepest parts of the ocean, we must understand that the ocean represents the unknown, the vast, mysterious place full of life and danger. It also happens to host some of the deepest points on Earth. The depths are so great that light takes years to reach here. No matter whether looking for something fun to do with friends or family, or just interested in what lies under the ocean, these 10 deep areas form a great location to see what lies beneath.
1. Deepest Parts of the Ocean: Challenger Deep, Mariana Trench
The Challenger Deep is the deepest part of the ocean, located in the Pacific Ocean. It’s 11 km deep — that’s about 3300 feet deeper than Mount Everest! It was discovered in 1960 by the US Navy and named after HMS Challenger, an oceanographic research vessel that disappeared during World War I.
2. Deepest Parts of the Ocean: Mariana Trench
The Mariana Trench is the deepest place in Earth’s oceans, located in the Western Pacific Ocean. It’s about 11 miles (18 kilometers) deep and has a width of about 6 miles (10 kilometers). The trench is named after the Marianas Islands group and other places that lie along its western rim, including Guam, Saipan, and Tinian.
The water at this depth is cold—about 8°C (46°F)—and contains almost no dissolved oxygen because there are no photosynthesizing plants or animals there to use it up as they grow. In fact, most life forms cannot survive without some kind of surface contact with air above or below them!
3. Deepest Parts of the Ocean: Tonga Trench
The Tonga Trench is a long, narrow oceanic trench in the south-central Pacific Ocean. It extends from about 10°S to 20°S and reaches its greatest depth at about 10,924 m (35,885 feet). The trench is bounded by two tectonic plates: the Pacific Plate to the north and east and South America’s Nazca Plate to its south.
Tonga Trench is a subduction zone where two converging plates meet at a deep point along their margins. Subduction zones result when one plate slides beneath another; they are typically found at mid-ocean ridges where three converging plates meet together or underneath continents such as Africa’s West African Rift Valley or Eurasia’s Fennoscandian Shield.[1]
4. Deepest Parts of the Ocean: Philippine Trench
The Philippine Trench is located in the western Pacific Ocean and has a depth of 11,033 meters. It is one of the deepest parts of our planet, which means it’s home to some pretty incredible creatures.
The trench itself was formed when two tectonic plates collided with each other around 60 million years ago. This collision created a mountain range that extends from Japan to New Guinea and is known as the Yokosuka Escarpment (Yokosuka being its Japanese name). The Philippine Trench on this side of this mountain range is deeper than most places on Earth!
5. Deepest Parts of the Ocean: Kuril-Kamchatka Trench
The Kuril-Kamchatka Trench is the deepest part of the ocean, located in the Pacific Ocean near Japan. It’s about 10,994 meters deep (6 miles), which makes it so deep that it’s hard to reach with conventional submarines or ships. However, scientists have been able to study this area using robots that can travel thousands of feet below sea level.
The Kuril Islands surround this trench on three sides: Hokkaido Island in Japan; Sakhalin Island in Russia; and Kamchatka Peninsula in Russia and/or Alaska (depending on who you ask). These islands are home to many active volcanoes—which means that when an earthquake occurs there could be serious consequences for nearby areas like Tokyo or Sendai City!
6. Deepest Parts of the Ocean: Kermadec Trench
The Kermadec Trench is located in the South Pacific Ocean and is the deepest part of any trench on Earth. It’s also one of the most remote places on our planet, with no nearby landmasses to drive ships or boats into it.
The deepest part of this trench is 7,924 meters (25,000 feet) below sea level; that’s more than three miles down! That makes it nearly twice as deep as any other oceanic trench—and it holds plenty of surprises beyond just being so far down: like how stunningly blue and alive it looks when viewed from above during an expedition aboard Google’s Nautilus submarine.
7. Deepest Parts of the Ocean: Izu-Oeno Trench
The Izu-Oeno Trench is located in the Pacific Ocean, off the coast of Japan. It’s one of the deepest parts of our planet and has been explored by humans for centuries. Its depth makes it a perfect place for researchers to study marine life and ecosystems in their natural environment (as opposed to being on land).
The first person who discovered this trench was an American scientist named John Strong Jr., who happened upon it during his research into earthquakes back in 1894. He guessed that there must be something extraordinary about this area if no one had ever seen anything like it before—so he took some samples back with him!
8. Deepest Parts of the Ocean: Japan Trench
The Japan Trench is a long submarine trench in the Pacific Ocean, located off the coast of Japan. It’s about 10,994 m (35,814 ft) deep and it’s been named for its location on Earth’s tectonic plate boundaries between Eurasia and North America. In fact, it’s so deep that it could be considered one of the deepest places on our planet!
The bottom of this trench has never been explored by humans because there are no roads leading down into this remote section of the ocean floor—and even if there were roads leading down here; they wouldn’t last long because they’d get covered in mud after just one trip through them once every few years due to constant flooding by stormy weather conditions like hurricanes blowing across these waters all year round
9. Deepest Parts of the Ocean: Puerto Rico Trench
The Puerto Rico Trench is located east of the island of Puerto Rico, at a depth of 8.5 miles (14 kilometers). It’s one of the deepest points in the ocean and scientists have been studying it for years.
The trench itself has been formed by tectonic plate movement—the shifting plates that make up Earth’s crust—and it’s part of a chain known as the Mid-Atlantic Ridge line where two tectonic plates meet. This area was once thought to be relatively flat, but recent studies show it dips down into an abyssal plain filled with seawater that reaches depths over 6 miles (10 km).
10. Deepest Parts of the Ocean: South Sandwich Trench
The South Sandwich Trench is a subduction zone located at the boundary between the South American Plate and the Antarctic Plate. This trench has an average depth of 7,235 m (23,749 ft) and lies between Cape Horn and Antarctica. It was first discovered by English naturalist Edward Bransfield in February 1838 after he had set out on an expedition aboard HMS Acheron (1837).
The deepest point here is also known as “the Abyss” or “the Profundity” because it looks like nothing else on Earth: it’s pitch black with no bottom glow whatsoever!
11. Deepest Parts of the Ocean: Peru–Chile Trench
The Peru–Chile Trench is located in the Pacific Ocean between Peru and Chile. It was discovered in 1960 by a US Navy expedition led by Jacques Piccard, who was testing submarine technology at the time. The trench is 10,200 meters deep—that’s about 33 miles!
The water here is very cold (about -2°C). This can be attributed to its high pressure due to being so far down on the ocean floor. The pressure causes gases like oxygen and nitrogen to dissolve into it instead of escaping out through bubbles or other openings that might exist at lower levels where there’s more sunlight available for photosynthesis; this makes up most of what we call “oceanic” waters today.”
These are the ocean’s deepest parts
The Challenger Deep is the deepest part of any ocean on Earth. In fact, it’s so deep that it’s deeper than all but two other places: Anadir and Mariana Trench in the Western Pacific Ocean near Guam. The Challenger Deep measures 11,000 meters (36,200 feet) below sea level—that’s six times more than Mount Everest! It’s also more than twice as deep as Lake Baikal or Lake Michigan.
