If you drop a brick into the Mariana Trench at a depth of 11,000 meters, the water pressure will shatter your imagination.
How Fast Does a Brick Sink in the Mariana Trench? Within Minutes
The Mariana Trench is known as one of the deepest underwater areas on Earth, with a depth of approximately 11,000 meters. If we 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 the Brick
Bricks are typically made from raw materials like clay, cement, and sand, giving them a certain density. Based on the density calculation formula, we can infer that the density of bricks is approximately 1.6 ~ 2.4 g/cm3. Due to the depth of the Mariana Trench, the underwater pressure is so immense that it can cause the brick to sink even faster.

The Role of Gravity and Buoyancy
When we drop a brick into the ocean trench, the first factor 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 it and inversely proportional to its mass. This means that the brick accelerates as it sinks. At the same time, buoyancy gradually increases, hindering the brick’s sinking speed.
Calculating the Time for a Brick to Sink in the Mariana Trench
Based on the density of the brick and the depth of the Mariana Trench, we can use physics formulas to estimate the time it takes for the brick to sink. However, accurately calculating the time for a brick to sink is nearly impossible due to the influences of buoyancy, the brick’s shape, and other complex factors that may arise.
The Fate of Bricks in the Mariana Trench: Crushed by Sea Pressure
The Mariana Trench, a deep-sea canyon located in the western Pacific, is world-renowned for its stunning depth and powerful oceanic forces.

Bricks, a common construction material used in buildings and other architectural projects, are carefully crafted by humans to form sturdy walls and foundations. However, at the bottom of the Mariana Trench, this solid structure will gradually be destroyed by the immense water pressure.
As the brick enters the Mariana Trench, it will encounter extreme water pressure. The depth of this ocean canyon exceeds 10,000 meters, equivalent to the height of 30 Eiffel Towers. At such depths, the pressure per square inch can reach over 1,600 atmospheres. The bricks will endure this tremendous water pressure, while their structures will continuously be compressed and deformed in such a harsh environment.
As the bricks sink to the ocean floor, the temperature of the surrounding water will significantly drop. At the bottom of the Mariana Trench, the water temperature is nearly freezing, typically around 0 degrees Celsius. This low temperature will adversely affect the brick’s structure. As the water temperature decreases, moisture freezes into ice within the brick, causing its volume to expand and leading to cracks and fragmentation. This accelerates the brick’s destruction, making it more brittle and fragile.

The marine environment in the Mariana Trench is also very hazardous. The seawater is rich in acids and corrosive chemicals that will penetrate the brick’s surface, destroying its internal structure and further weakening its durability. Under such conditions, bricks cannot withstand the erosion and corrosion from seawater and will eventually crumble into debris.
Bricks will also face threats from currents in the Mariana Trench and earthquakes. The strong and swift currents in the ocean will continuously impact the bricks, further damaging their structure. Additionally, the Mariana Trench is part of an active seismic region, and frequent seismic activity will cause even greater damage to the bricks.
