You might expect the waters of the Mariana Trench to be frigid since no sunlight can reach it. And you’d be right. The water there tends to range between 34 to 39 degrees Fahrenheit. But what’s surprising is how hot the water can get, too.
The temperature at the bottom is 1 to 4 °C (34 to 39 °F). In 2009, the Marianas Trench was established as a US National Monument.
On 23 January 1960, two explorers, US navy lieutenant Don Walsh and Swiss engineer Jacques Piccard, became the first people to dive 11km (seven miles) to the bottom of the Mariana Trench.
How cold is the Mariana Trench in Celsius?
The thermocline varies in thickness from about 1,000 feet to 3,000 feet. Below this point water cools more slowly. At areas like the Mariana Trench (or the Marianas Trench; both spellings are commonly found) the water temperature ranges from 34-39 degrees F (1-4 degrees C).
Why is it so cold in the Mariana Trench?
Cold water has a higher density than warm water. Water gets colder with depth because cold, salty ocean water sinks to the bottom of the ocean basins below the less dense warmer water near the surface.
Has a megalodon been found in the Mariana Trench?
The Carcharocles megalodon, better known as the megalodon, was the world’s biggest-ever shark, whose name means big tooth.
The pressure from the water would push in on the person’s body, causing any space that’s filled with air to collapse. (The air would be compressed.)

Why is Mariana Trench so deep?
One reason the Mariana Trench is so deep, he added, is because the western Pacific is home to some of the oldest seafloor in the world—about 180 million years old. Seafloor is formed as lava at mid-ocean ridges. When it’s fresh, lava is comparatively warm and buoyant, riding high on the underlying mantle.
Why is it called Mariana Trench?
The Mariana Trench was first pinpointed in 1875 during the undertaking of a global circumnavigation. It was found by utilizing sounding equipment on the HMS Challenger. It was named for the nearby Mariana Islands.

Do Megalodons still exist 2020?
There is no record, they completely vanish. The only valid conclusion is megalodon became extinct. This shows the evolution of the megalodon, from a small Cretaceous shark to the apex predator of the Pliocene. After the Pliocene, megalodon fossils are no longer present.
