This story is an English language news item from CGTN. CGTN is a Chinese state-funded broadcaster.
China is the third largest country in the world by area and the largest country in the world by population. Properly known as the People’s Republic of China, the political territory of the country includes Tibet and Hong Kong. The capital is Beijing.
The Mariana Trench is the deepest oceanic trench on Earth.
It is located in the western Pacific Ocean about 200 kilometres (124 mi) east of the Mariana Islands. The maximum known depth is 10,984 metres (36,037 ft) (6.825 miles) at a point known as the Challenger Deep.
If Mount Everest were placed into the trench at this point, its peak would still be under water by more than two kilometres (1.2 mi).
At the bottom of the trench the water column above exerts a pressure of 1,086 bars (15,750 psi), more than 1,071 times the standard atmospheric pressure at sea level. At this pressure, the density of water is increased by 4.96%. The temperature at the bottom is 1 to 4 °C (34 to 39 °F).
In 2009, the Marianas Trench was established as a United States National Monument.
Microbes have been found within the mud at the bottom of the trench.
The Pacific Ocean is the largest and deepest of Earth’s oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean in the south and is bounded by the continents of Asia and Australia in the west and the Americas in the east
