Is there a monster in the Mariana Trench?
Despite its immense distance from everywhere else, life seems to be abundant in the Trench. Recent expeditions have found myriad creatures living out their lives at the bottom of the sea-floor. Xenophyophores, amphipods, and holothurians (not the names of alien species, I promise) all call the trench home.
How cold is the Mariana Trench?
At the bottom of the trench, the water column above exerts a pressure of 1,086 bars (15,750 psi), more than 1,071 times the standard atmospheric pressure at sea level. At this pressure, the density of water is increased by 4.96%. The temperature at the bottom is 1 to 4 °C (34 to 39 °F).
Are there fish in the Mariana Trench?
In the Mariana Trench—7,000 meters below the ocean’s surface—these fish makes a living in total darkness and at crushing pressures that can reach 1,000 times more than at sea level. But the Mariana snailfish is not only abundant in this area; it’s the region’s top predator.
Has a megalodon been found in the Mariana Trench?
‘Megalodon 100 tonne shark’ filmed in Mariana Trench When you subscribe we will use the information you provide to send you these newsletters. The Megalodon has since gone extinct but shark experts worldwide are still discovering its monstrous teeth.
What is the mystery of Mariana Trench?
The depth of the Mariana Trench makes it one of the deadliest places on the planet. Forever covered in darkness, water temperature is below 0 degree Celsius. What makes it near impossible for life as we know it to exist is the extreme water pressure. 8 tonnes per square inch increases with depth.
Is there drilling in the Mariana Trench?
Fishing, drilling and mining are prohibited in the Marianas Trench National Marine Monument but because of its potential as a source of energy, its sanctuary designation is at risk for recall.
What does it look like in the Mariana Trench?
How deep is the Mariana Trench? The Trench sits like a crescent-shaped dent in the floor of the Pacific Ocean, extending over 1500 miles long with an average width around 43 miles and a depth of almost 7 miles (or just under 36,201 feet). For comparison, most ocean life lives above a depth of 660 feet.
What do you hear at the bottom of the ocean?
Most of the sounds the hydrophone records emanate from high up in the water or on its surface — such as the calls of sea lions, the wind and the pitter-patter of rain. But high-pitched sounds like dolphin clicks can’t travel as far.
Is water under silent?
But we can barely hear underwater sound when we’re standing in the air, because the water surface acts like an acoustical mirror from both sides. The dense, strongly-bonded molecules in water can’t push efficiently on the loose, freely-travelling molecules in air, so very little sound travels across the boundary.
What do you call the sound underwater?
Underwater acoustics is sometimes known as hydroacoustics. The field of underwater acoustics is closely related to a number of other fields of acoustic study, including sonar, transduction, acoustic signal processing, acoustical oceanography, bioacoustics, and physical acoustics.
Can humans hear underwater?
On land, humans hear through air conduction. Sound pressure waves cause tiny disturbances in the air that travel into the ear canal and vibrate the ear drum, which is connected to the three smallest bones in the body, the ossicles of the middle ear. But underwater, humans don’t hear using the normal channels.
Does space have sound?
Sound travels in waves like light or heat does, but unlike them, sound travels by making molecules vibrate. On Earth, sound travels to your ears by vibrating air molecules. In deep space, the large empty areas between stars and planets, there are no molecules to vibrate. There is no sound there.
Are explosions silent in space?
Sound needs a medium to travel (such as air), but space generally doesn’t have it. Therefore, sound can’t really propagate in space. So you can’t hear an explosion or any other sound in space.
Is a fart louder than a supernova?
Since there is no sound in space a fart is louder than a supernova(star exploding) The fart will make no noise also.
How loud is a supernova if we could hear it?
If you take as your maximum a sound that is loud enough to compress air to the density of a neutron star then that’s a maximum of 724 dB.
What is inside Sun?
The Sun, like others stars, is a ball of gas. In terms of the number of atoms, it is made of 91.0% hydrogen and 8.9% helium. By mass, the Sun is about 70.6% hydrogen and 27.4% helium.
What does our sun sound like?
The sound itself would be something like a dull roar, deForest says, because the sound waves coming at us would be composed of so many different frequencies. Imagine standing next to Niagara Falls all of the time (it would actually be even louder — Niagara clocks in at around 90 decibels).
