Where is the deepest photic zone?
The deepest layer of the ocean, below 19,686 ft (6,000 m), is called the hadal zone. All of these zones receive a constant rain of organic debris and wastes from the photic zone which serves as a organic material for the organisms living in the deeper volumes.
Is the photic zone shallow?
Coral reefs are characterized by high biodiversity and the structures created by invertebrates that live in warm, shallow waters within the photic zone of the ocean.
How much pressure is in the photic zone?
Photic Zone Food Chain The temperature in this region ranges around 100 to 30 degrees Fahrenheit, while the pressure ranges around 15 to 300 pounds per square inch. Such an environment is very conducive for life. Hence, you can find a wide variety of animals and plants in the photic zone biome.
What zone is complete darkness?
the aphotic zone After the aphotic zone, there's complete darkness. From 1,000 meters below the surface, all the way to the sea floor, no sunlight penetrates the darkness; and because photosynthesis can't take place, there are no plants, either.
What is in the photic zone?
Photic Zone is the top layer, nearest the surface of the ocean and is also called the sunlight layer. In this zone enough light penetrates the water to allow photosynthesis.
What’s below the photic zone?
The Disphotic Zone is found just below the Photic Zone and is known as the twilight layer. In this zone only a small amount of light penetrates the water. Plants do not grow here due to the insufficient amount of light. The darkness layer or Aphotic Zone is entirely dark meaning there is no light.
What is the depth of the open ocean?
about 12,100 feet As far as we know, the ocean is 36,200 feet (11,000 m or almost 7 miles) deep at its deepest point. On average, the ocean is about 12,100 feet (3,688 m) deep.
At what depth is there no light?
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 is the Mariana Trench?
36,201 feet 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 Mariana Trench, the peak would still be 2,133 meters (7,000 feet) below sea level. Show students NOAA's Mariana Trench animation.
How deep does the ocean go down?
35,876 feet The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 10,935 meters (35,876 feet) deep.
Is there anywhere deeper than the Mariana Trench?
2:339:32Scientists Have Discovered A Place Deeper Than The Mariana Trench …YouTube
How deep can humans go in the ocean?
That means that most people can dive up to a maximum of 60 feet safely. For most swimmers, a depth of 20 feet (6.09 metres) is the most they will free dive. Experienced divers can safely dive to a depth of 40 feet (12.19 metres) when exploring underwater reefs.
How deep is the ocean pitch black?
The Abyssopelagic Zone (or abyssal zone) extends from 13,100 feet (4,000 meters) to 19,700 feet (6,000 meters). It is the pitch-black bottom layer of the ocean.
Is it pitch black in the deep sea?
After the aphotic zone, there's complete darkness. From 1,000 meters below the surface, all the way to the sea floor, no sunlight penetrates the darkness; and because photosynthesis can't take place, there are no plants, either.
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 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).
Has anyone been to bottom of Mariana Trench?
The first and only time humans descended into the Challenger Deep was more than 50 years ago. In 1960, Jacques Piccard and Navy Lt. Don Walsh reached this goal in a U.S. Navy submersible, a bathyscaphe called the Trieste.
How deep has a human gone?
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).
Is there a door at the bottom of the Mariana Trench?

Can you fart while diving?
Farting is possible while scuba diving but not advisable because: Diving wetsuits are very expensive and the explosive force of an underwater fart will rip a hole in your wetsuit. An underwater fart will shoot you up to the surface like a missile which can cause decompression sickness.
Can you dive to the Titanic?
You cannot scuba dive to the Titanic due to its depth at 12,500 feet. Air consumption: one standard tank lasts 15 minutes at 120 feet. Supply for 12,500 feet would be impossible to carry even with a team. The deepest dive on record with special equipment, training and a support team is 1,100 feet.
How deep can you go in the ocean without dying?
For most swimmers, a depth of 20 feet (6.09 metres) is the most they will free dive. Experienced divers can safely dive to a depth of 40 feet (12.19 metres) when exploring underwater reefs.
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.

Has anyone scuba dived to the Titanic?
So, can you scuba dive to the Titanic? No, you cannot scuba dive to the Titanic. The Titanic lies in 12,500 feet of ice cold Atlantic ocean and the maximum depth a human can scuba dive is between 400 to 1000 feet because of water pressure. The increasing water pressure also restricts blood flow by constricting tissue.
Could the Megalodon live in the Mariana Trench?

Why have we not drilled or mined into Earth?
As depth increases into the Earth, temperature and pressure rise. Temperatures in the crust increase about 15 °C per kilometer, making it impossible for humans to exist at depths greater than several kilometers, even if it was somehow possible to keep shafts open in spite of the tremendous pressure.
What is hidden at the bottom of Mariana Trench?
But if you thought the trench could escape the global onslaught of plastics pollution, you would be wrong. A recent study revealed that a plastic bag, like the kind given away at grocery stores, is now the deepest known piece of plastic trash, found at a depth of 10,975 meters (36,000 feet) inside the Mariana Trench.
Why do divers enter the water backwards?
The Backward Roll Helps Keep Boats Stable While these boats may have a low center of gravity, a few divers standing on the gunwale will shake things up on board. By entering the water with a backwards fall, you minimize this rocking motion for everyone else on board.
