1. Death icicles are the most terrifying killer on the ocean floor
The creatures that encounter it
have no choice but to die
are formed in the common sense of humans
Starting from the surface of the rivers, lakes and seas
, even if the weather is severely cold, the ice formed by
is thicker
the life under the ice
can still be well protected in the waters under the ice
to survive the harsh winter warm
However, in the 1960s,
scientists discovered death icicles
that reached the bottom of the sea in the polar waters
. These icicles quietly extend from under the ice to the seafloor
and ruthlessly kill the ice on the way. All life
This terrible anomaly shocked the scientific community
to affect human exploration of alien life
because in those alien planets
with higher salinity and lower temperature It is easy to form large-scale death icicles
and kill those fragile lives that could have survived under thick ice.
The real existence of death icicles
Let us have frozen ice in Europa and Enceladus
The planet’s search for extraterrestrial life
has become hopeless
The meaning of water for life
Scientists believe that water is just like
specially designed by God for life. Water is not only the best solvent and reaction for the chemical reactions of life. Place
The physical properties of water are the greatest protection for life.
Generally, the lower the temperature, the lower the density, the lower the density.
, but the maximum density of water is about 4 degrees Celsius. The maximum density of
is lowered.
So although ice is a solid form of water
, its density is lower than water br6 br This is why ice floats on the water surface
and even forms icebergs without sinking
If water is in a solid state like most substances, the density increases
, then the upper layer of ice will sink to the bottom
not only kills life on the bottom
but also on the surface The icing will continue to sink
, and the entire ocean will become a piece of ice
. Life will die out
life is lucky
ice does not seem to extend to the bottom of the sea
but death icicles The existence of
completely broke this lucky
, what exactly is this death icicle?
2. The quietest killer in the world,
. During World War II,
. The Soviets discovered that their mines
in the shallow sea of the Arctic Ocean would explode
inexplicably, which caused huge losses and waste to the navy and sailed on
. The submarine
under the ice of the Arctic Ocean is also often hit and scratched by some unknown hard objects.
, which often causes damage and destruction to the submarine.
hits the morale of the submarine force.
. At that time, there were reports that this was a seabed knot. _Span2span
However, experts believe that this is against common sense.
is impossible to exist. It was not until the 1960s that
. With the continuous advancement of photography and camera technology,
was finally taken from the sea. The huge icicles under the ice layer
that extend to the bottom of the sea
These icicles
are often caused by a sharp drop in the sea surface temperature
, especially when the temperature drops from ten degrees below zero
to minus At 30 degrees Celsius, the lower the temperature
, the larger the size of the icicles produced by
, the faster the speed
. These icicles extend to the bottom of the sea at a slow speed that seems to be silent,
, so that the fish and other seas on the bottom of the sea Creatures like shrimp
starfish
completely ignore this silent freezing
but when they come into contact with these icicles
it is too late
the icicles will suddenly freeze their bodies severely and suddenly
these animals will be I found that a part of my body was completely unable to move
, and then I froze my whole body
, and watched myself go to death
In this slow and cruel process,
death icicles will ruthlessly sweep away all the blocks. The life on its road
is even more terrifying. The death icicle does not stop freezing
when it touches the bottom of the sea, but accelerates ten times
and continues to expand the frozen area along the bottom of the sea. Area
in this area
is the restricted zone of life
So how exactly are the death icicles formed?
3. Death icicles,Is the most terrifying killer on the seabed
, wherever he went, marine life was frozen to death
Because of the "death icicles"
is of great significance for studying the environment of life
. Scientists from all over the world have started to talk about
. "Death icicles" conducted in-depth research on
and finally discovered the reason for its formation.
is a "salt water cooling cycle" mechanism.
. When the sea surface encounters a rapid drop in temperature, the ice layer formed by
is below minus 21.7 degrees Celsius. There is a temperature difference of nearly 20 degrees
. At this time, the seawater under the ice layer is minus 1.9 degrees
. This temperature difference causes the heat of the seawater to rapidly conduct to the sea ice layer
while the sea air continues Cooling
This kind of heat conduction will be extremely fast
, which will force the sea water to precipitate out the salt
to form super saline water
. The temperature of this super saline water can be lowered to a lower
density,
, and finally form icing
icing At the moment
will completely separate out the salt and impurities in the ice,
will form a saltier seawater
, which will form a chain reaction
and extend downward in a spongy manner,
will continue to absorb more salt water
and be like a ghost snake
It winds and follows the low temperature and salt water and continues to extend and freeze
When the death icicle touches the bottom of the sea,
The heat capacity of the seabed is much lower than that of the seawater. The heat loss rate is instantaneous. Accelerate
, and the ice on the seabed will be nearly ten times faster than in the sea.
The death icicles are like the fingers of the ice queen.
. The moment they touch the seabed, they will freeze the seabed
. Life has no time to escape.
Wherever it went
Leaving no vitality
It is conceivable that the environment of
is far inferior to Europa,
, Enceladus , and the saltiness of the harsh water of the frozen planet
is also far lower Other planets
in those sub-zero temperatures More than one hundred degrees
The ice layer is hundreds of kilometers thick, under the extraterrestrial ice layer,
The scale of death icicles
will be so magnificent
Here
I am looking forward to human beings set foot on those planets
to show us the alien underwater world Moment...
like me,please follow me!
See you next time!
