Despite immense pressure, the water in the deepest parts of the ocean, like the Mariana Trench, remains incredibly cold, typically between 1-4°C (34-39°F). This is because sunlight cannot penetrate these depths, and cold, dense surface waters eventually sink to fill these abyssal plains, creating a perpetually frigid environment.
The Mariana Trench in the western Pacific Ocean plunges to nearly 36,070 feet (10,994 meters) at its Challenger Deep. If Mount Everest were placed at this spot, its peak would still be over a mile underwater.
The Mariana Trench, nearly 11,000 meters deep, experiences pressures over 1,000 times that at sea level. This crushing force is roughly equal to stacking 50 jumbo jets on top of a person, yet life still thrives there, adapted to extreme conditions.
