the Philippine trench.
The third deepest point in the world, the Galathea Depth in the Philippine trench, is 10.54 km below sea level. Also known as Mindanao Trench, this submarine trench is located in the Philippine Sea and spreads in a length of 1,320km and 30km in width in the east of the Philippines.

What are the top 5 deepest ocean trenches in the world?
The Five Deeps Expedition was the first to reach the deepest point in each of the Earth’s five oceans: the Puerto Rico Trench in the Atlantic, South Sandwich Trench in the Southern Ocean, Java Trench in the Indian Ocean, Challenger Deep in the Pacific and Molloy Deep in the Arctic.
What are the 3 deepest parts of the ocean?
The deepest place in each ocean are the Molloy Hole in the Fram Strait (Arctic Ocean; 5669 m, 79.137° N/2.817° E), the trench axis of the Puerto Rico Trench (Atlantic Ocean; 8408 m 19.613° N/67.847° W), an unnamed deep in the Java Trench (Indian Ocean; 7290 m, 11.20° S/118.47° E), Challenger Deep in the Mariana Trench
What is the 2nd deepest trench in the world?
The Tonga Trench is an oceanic trench located in the southwestern Pacific Ocean. It is the deepest trench in the Southern hemisphere and the second deepest on Earth after the Mariana Trench.
How deep are the three deepest trenches in the ocean?
What Is An Oceanic Trench And Which Are The Deepest Oceanic Trenches In The World?
| Rank | Name | Depth (feet) |
|---|---|---|
| 1 | Challenger Deep | 36,197 |
| 2 | Tonga Trench | 35,702 |
| 3 | Galathea Depth | 34,580 |
| 4 | Kuril-Kamchatka Trench | 34,449 |
Why is the ocean blue?
The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.
What is the deepest thing on Earth?
The Mariana Trench, in the Pacific Ocean, is the deepest location on Earth.
Which ocean is coldest?
The Arctic Ocean
The Arctic Ocean | National Geographic Society.
At what depth is the ocean dark?
Such a minuscule amount of light penetrates beyond a depth of 200 meters that photosynthesis is no longer possible. The aphotic zone exists in depths below 1,000 meters. Sunlight does not penetrate to these depths and the zone is bathed in darkness.
How deep has a human gone in the ocean?
35,853 feet
Vescovo’s trip to the Challenger Deep, at the southern end of the Pacific Ocean’s Mariana Trench, back in May, was said to be the deepest manned sea dive ever recorded, at 10,927 meters (35,853 feet).
How many trenches are there?
Of the Earth’s 20 major trenches, 17 are found in the Pacific basin, a vast area rimmed by trenches of both marginal and island arc varieties. Marginal trenches bound the west coast of Central and South America from the Gulf of California to southern Chile.
Which ocean is the warmest?
the Pacific Ocean
Looking at the entire oceans, however, the Pacific Ocean is by far the warmest overall ocean because it has about four times the intense sun-heated surface area in the tropics compared with the Atlantic Ocean.
Is there anything deeper than the Mariana Trench?
The deepest place in the Atlantic is in the Puerto Rico Trench, a place called Brownson Deep at 8,378m. The expedition also confirmed the second deepest location in the Pacific, behind the Challenger Deep in the Mariana Trench. This runner-up is the Horizon Deep in the Tonga Trench with a depth of 10,816m.
Are there monsters in the Mariana Trench?
Despite its immense distance from everywhere else, life seems to be abundant in the Trench. Recent expeditions have found myriad creatures living out their lives at the bottom of the sea-floor. Xenophyophores, amphipods, and holothurians (not the names of alien species, I promise) all call the trench home.
How cold is the Mariana Trench?
34-39 degrees F
At areas like the Mariana Trench (or the Marianas Trench; both spellings are commonly found) the water temperature ranges from 34-39 degrees F (1-4 degrees C).
How old is Mariana Trench?
“In order for this to sink back into the earth, it has to bend downward, and these are very gentle bends.” One reason the Mariana Trench is so deep, he added, is because the western Pacific is home to some of the oldest seafloor in the world—about 180 million years old.
Why is the ocean salty?
From precipitation to the land to the rivers to the sea
The rain physically erodes the rock and the acids chemically break down the rocks and carries salts and minerals along in a dissolved state as ions. The ions in the runoff are carried to the streams and rivers and then to the ocean.
What color is the sky really?
bluish violet
As far as wavelengths go, Earth’s sky really is a bluish violet. But because of our eyes we see it as pale blue.
Can you filter ocean water to drink?
Humans cannot drink saline water, but, saline water can be made into freshwater, for which there are many uses. The process is called “desalination”, and it is being used more and more around the world to provide people with needed freshwater.
What are the deepest things?
8 of the deepest places Earth can offer

- Mariana Trench. The first ever dive to the bottom of the ocean.
- Dormant volcano, Iceland. You can visit inside Thrihnukagigur Volcano.
- Mponeng, South Africa.
- Lake Baikal.
- Bentley Subglacial Trench.
- Red Sea, Egypt.
- Majlis al Jinn cave.
Who lives at the bottom of the earth?
The three most common organisms at the bottom of the Mariana Trench are xenophyophores, amphipods and small sea cucumbers (holothurians), Gallo said. “These are some of the deepest holothurians ever observed, and they were relatively abundant,” Gallo said.
