Mariana Trench - What's mysterious about the deepest part of the ocean?

If you throw a brick into the Mariana Trench at a depth of 11,000m, the water pressure will shatter your imagination.

How quickly bricks sank into the Mariana Trench: within minutes

The Mariana Trench is known as one of the deepest underwater areas on Earth, with a depth of about 11,000 meters. If you drop a brick from above, how long will it take for the brick to sink to the bottom of the trench?

Density and sinking speed of bricks

Bricks are generally made of raw materials such as clay, cement and sand and have a certain density. According to the density calculation formula, we can deduce that the density of bricks is approximately 1.6~2.4 grams/cm3 . Due to the depth of the Mariana Trench, the underwater pressure is so great that it can cause bricks to sink faster.

The role of gravity and water resistance

When we drop a brick into an ocean trench, the first thing that comes into play is gravity . According to Newton's second law, the acceleration of an object is directly proportional to the force acting on the object and inversely proportional to the mass of the object. This means that the brick will accelerate as it sinks. At the same time, the resistance to water will gradually increase, hindering the speed at which the brick sinks.

Calculate the time it takes for a brick to sink into the Mariana Trench.

Based on the density of the brick and the depth of the Mariana Trench, we can use physics formulas to calculate the time it takes for the brick to sink. However, calculating the exact time it takes for a brick to sink is almost impossible , due to the influence of water resistance, the shape of the brick, and other complex factors that may occur.

Fate of Mariana Trench Bricks: Crushed by Sea Pressure

The Mariana Trench, a deep-sea canyon in the western Pacific Ocean, is world-famous for its stunning depths and powerful ocean forces.

Bricks, a building material commonly used in buildings and other structures, are carefully constructed by humans to form strong walls and foundations. However, at the bottom of the Mariana Trench, these strong structures are gradually being destroyed by the immense water pressure.

When the brick enters the Mariana Trench, it will encounter tremendous water pressure . The depth of this ocean canyon exceeds 10,000 meters, equivalent to the height of 30 Eiffel Towers. At such a deep depth, the pressure per square inch can reach more than 1,600 atmospheres. The bricks will withstand this terrible water pressure, and their structure will be continuously compressed and deformed in such a harsh environment.

As the bricks sink to the bottom of the deep ocean, the temperature of the surrounding water drops dramatically. At the bottom of the Mariana Trench, the water temperature is near freezing, often around 0 degrees Celsius. This low temperature will have a negative impact on the structure of the bricks. As the water temperature drops, moisture freezes into ice inside the brick, causing it to expand in volume and crack and crumble. This will accelerate the destruction of the bricks, making them more brittle and prone to breaking.

Low temperatures in the Mariana Trench will adversely affect the structure of bricks.

The marine environment in the Mariana Trench is also very dangerous. The seawater is rich in acids and corrosive chemicals that will penetrate the surface of the tiles, destroying the internal structure and further weakening the durability of the tiles. In such conditions, the tiles cannot withstand the erosion and corrosion from the seawater and will eventually crumble into pieces.

The bricks will also face threats from currents in the Mariana Trench and earthquakes. Strong, fast-moving ocean currents will constantly impact the bricks, further damaging their structure. Additionally, the Mariana Trench is part of an active seismic zone, and frequent seismic activity will cause further damage to the bricks.
