The average depth of the world's oceans is approximately 3,347 meters.
The deepest part of the World Ocean is the Mariana Trench in the Pacific Ocean. The deepest reaches 11,034 meters. It is located near the Philippines and was formed after the subduction of the Pacific plate under Eurasia. Plate.
With their bare hands, some people have created depths greater than 400 meters. They quickly sank with the help of ropes and heavy objects, and quickly floated with the help of airbags, but without oxygen or pressure relief. equipment, this was essentially excluding the use of diving equipment. Wear a wetsuit and use oxygen. Safe diving depth is approximately 400 meters.
If you want to dive deeper, you must use special oxygen, which is a mixture of oxygen and rare gases. You can dive deeper, but the risk is stillincreased ore, mainly because blood dissolves other gases.
Classification of ocean depth:
The depth of the ocean is divided into 5 layers of water: the upper ocean layer ( above 200 meters), middle ocean layer (200 meters to 1,000 meters), deep ocean layer (1 kilometers to 4 kilometers), abyssal ocean layer (4 kilometers to 6 kilometers), ultra-abyssal ocean layer ( less than 6 kilometers).
Depending on the intensity of sunlight passing through it, the layer of water from the surface of the ocean to a depth of 200 meters is called the upper layer of the ocean. Sunlight penetrates here through the sea water and the water is brighter. , and the sea water is azure and blue. The layer of water from 200 meters to 1000 meters deep is called the middle layer of the ocean. The sunlight here cannot completely penetrate the sea water, lThe light is very weak and the sea water is very weak. black and blue.
The layer of water from 1,000 meters to 4,000 meters is called the semi-abyssal layer. There is no sun here, it is dark and it is a dark world below 4,000 meters, it is the abyssal layer. and it's even darker here, but most fish in the semi-abyssal and abyssal layers have luminous organs to help them find food and move around in dark, lightless environments.
