Mystery and research of the Mariana Trench
To understand all the strange things going on in the Mariana Trench, we must first understand its sheer size. It’s easy to think that this place is just a deep, water-filled hole, home to some terrifying bioluminescent creatures.
However, in reality, the Mariana Trench is really huge. The trench is about 2,550 km (1,580 mi) long but has an average width of only about 69 km (43 mi). The bottom of this trench is a much greater distance below sea level than Mount Everest is above sea level.
The Mariana Trench is the deepest trench in the world, located in the western Pacific Ocean, with a depth of about 11,000 meters. This trench contains many mysterious and shocking phenomena, one of which is that it swallows a huge amount of sea water, about 3 billion tons of sea water each year. This phenomenon has puzzled scientists for many years, they have conducted a lot of research but still cannot fully explain the cause.

The depth of the Mariana Trench makes it an important location for the exchange of hot and cold water between oceans. As temperatures change, these fluids move through the ocean and create circulation.
The Mariana Trench is considered a major component of the deep water cycle. Deep water is a body of water deep in the ocean, separated from surface water and circulating between oceans. According to scientists’ observations, seawater swallowed by the Mariana Trench may be related to this cycle. And they may be part of deep waters originating from Antarctica. This deep water circulates through the global deep water cycle and eventually enters the Mariana Trench.
The Mariana Trench may also be associated with biological activity in seawater. The distribution and migration of organisms in the ocean is influenced by many different environmental factors, such as water temperature, nutrients, and ocean currents. Seawater swallowed by the Mariana Trench can contain large amounts of biota, microorganisms and organic matter. Studying these organisms can help us better understand the role of the Mariana Trench and its ecosystem.
Ocean trenches are formed by the subsidence of seafloor plates due to tectonic activity. As the plates sink beneath the Earth’s crust, they create degassing reactions in seafloor sediments, releasing large amounts of gases and liquids into seawater. These gases and liquids can cause the Mariana Trench to swallow large amounts of ocean water and are linked to deep-sea geological processes. Photo: Zhihu
The Mariana Trench swallowing such a huge amount of water is a complex and confusing phenomenon. Scientists have done some research on this issue, but more research and experimental evidence are still needed to reveal the truth. The answer to this question not only has great significance for scientific research in the field of oceanography, but also provides important references for us to better understand the Earth’s deep-sea environment. Land.
Sea level rise and the Mariana Trench
As global climate change intensifies, sea level rise has gradually become a global problem. Among them, the Mariana Trench, the world’s deepest trench, also attracts a lot of attention.
As one of the deepest trenches in the world, the Mariana Trench has an important impact on sea level rise. Increased sea water volume causes sea levels to rise, which further increases the depth of the Mariana Trench.
As the ocean expands and water volume increases, ocean currents gradually erode the crust, forming deeper depressions.

Topographic features such as mountains, canyons, and cliffs on the seabed guide the flow of seawater, forming large and complex flow systems that absorb part of the seawater. Photo: ZME
The Mariana Trench will also slow down sea level rise to a certain extent. The water pressure difference and hydrodynamic effects deep in the trench cause some of the water to flow into the trench, thereby reducing the amount of water in the ocean. These factors combine to make the Mariana Trench an equalizer for rising sea levels.
The Mariana Trench not only slows down the rate of sea level rise through water pressure and hydrodynamic effects, but also affects the change in the morphology of the Earth’s crust through subsidence, thereby affecting the trenches. deep water at the bottom of the ocean. Scientific decoding reveals the principles behind this phenomenon, providing a basis for us to better understand sea level rise and reminding us to take effective measures to solve this global problem.
The connection between the formation of the Mariana Trench and rising sea levels can be explained by geological and hydrodynamic principles. The rise in sea level due to global climate change increases the amount of sea water, which in turn affects the pressure distribution in the earth’s crust. The Earth’s crust sinks at depth due to increased water pressure, and this subsidence further deepens deep-sea trenches on the ocean floor. Photo: Discovermagazine
