Welcome to "Q-did you know ?".
I am Quisha who will accompany you on your journey to explore the world!
Humans are really small in front of nature.
Just a tsunami or a tornado will cause us countless losses.
But they are not yet the strangest and most frightening natural phenomenon.
Today, join me to find out the mystery of nature through the video of the
top 10 most horrible natural phenomena.
The first phenomenon will be truly terrifying.
Let's see what it is.
Number 10: “Cappuccino” coast
The phenomenon of the Cappuccino coast is
an extremely interesting phenomenon of nature.
The reason why this phenomenon is so-called because it can make a large coast flooded
with foam like Cappuccino cups in minutes.
The phenomenon of Cappuccino coast is the result when tidal waves mix seawater with
plankton and waste on the surface of the sea into the foam.
After that, the foam will follow the waves and drift to the shore.
The foam is so light that you can pick it up with your hands and blow away.
The phenomenon of Cappuccino coast is a very rare and interesting phenomenon.
The last time this happened was in August 2007 at Yamba beach, in New South Wales, Australia.
Earlier, the phenomenon of Cappuccino coast also occurred in Cape Town, South Africa.
Number 9: Fire rainbow
Mentioning this, you will surely imagine a
red arc in the sky, right?
In fact, it is not.
The fire rainbow is the appearance of a large colorful spectrum with the top color of red,
running parallel to the horizon, located far below the sun or the moon.
To put it simply, it is like someone burning a colorful strip of fire in the sky.
Recently, the image of a fire rainbow recorded in the sky of Malaysia created shock waves
among people.
Many people using social networks believe that this fire rainbow is an omen of apocalypse
or an impending disaster.
However, according to scientists, the fire rainbow crossing the sky is actually an optical
phenomenon and has appeared in other parts of the world.
The US National Aeronautics and Space Administration (NASA) calls this phenomenon with a softer
name, which is the iridescent cloud.
They also think that this phenomenon is relatively rare,
so the next time if you encounter this
phenomenon, you should quickly capture it!
Number 8: Bubble cloud
A perfect product of nature, and also completely
harmless, this meteorological phenomenon is called Mammatus cloud.
The "bubble clouds" that make up the spectacular scenery are called "Mammatus clouds" which
are rare as they are only created at medium altitudes and reflected by sunlight.
They look extremely strange, especially when they are seen so clearly.
These clouds will be seen more vividly when the sunset shines, creating beautiful colors.
Conventional clouds consist of water droplets, ice crystals or a mixture of both, and different
cloud shapes are made up of a number of factors such as temperature, water and ice ratio,
cloud height and inner wind speed.
However, while most clouds have thin, unclear margins, Mammatus clouds have unusually sharp
and clear boundaries.
Each "drop" of its can have a diameter of up to 1 mile.
They are also nearly opaque, making the cloud appear to be palpable.
And now is the most exciting part of today's video, which is "Ask and Answer"
A ferocious cloud like in apocalypse?

The reward for those who comment quickly with the rightest answers in the month is an extremely
cool "Apple Watch".
Let's go back to
Number 7: Colorful cloud
People often say "white as snow", but many times have humans witnessed strange phenomena
of snow with red, gray, black,...
Although very mysterious, scientists have gradually discovered the secret of this colorful
snow phenomenon.
Gray and black snow often occur due to environmental pollution.
A recent dark gray snowstorm in the city of Omsk, western Siberia is thought to be affected
by emissions from thermal power plants.
If you have the opportunity to climb the Nevada mountain in the US, you will come across the
image of red snow.
This phenomenon is also known as the "watermelon snow".
The watermelon snow is probably due to the watermelon's color and spongy appearance.
"Watermelon snow" is also known as "algae snow".
The red in the snow is formed by the microscopic algae Chlamydomonas growing underneath the snow.
Number 6: Tsunami
Tsunamis are one of the most frightening natural
disasters on Earth.
According to geologists, tsunamis come from earthquakes, geological movements both above
and below water, volcanic eruptions and the impact of meteorites on Earth.
Tsunamis have happened in many countries around the world, especially island nations like
Japan, the Philippines, Indonesia, etc.
But not everyone knows about the most terrible tsunami in history that happened in Lituya
Bay, Alaska, USA.
On the night of July 9th, 1958, a 7.7-8.3 Richter scale earthquake caused a massive
landslide on the northeast coast of Lituya Bay.
This has led to a tsunami as high as 524m, the largest tsunami in Earth's history.
The unbreakable power of the tsunami has caused millions of trees along the banks of the bay
to be uprooted and swept away as well as seriously damaged the three unfortunate boats anchored
in the bay.
Number 5: Penitentes
Do you remember that the Titanic got wrecked
on an iceberg?
So how scary it is if you encounter a Penitentes!
The phenomenon of crystallization of ice into sharp blocks growing side by side forms a
giant Penitentes, only found at high altitudes.
The height of each iceberg varies from a few centimeters to 2 meters or more.
The white, sparkling Penitentes has fascinated researchers since Darwin.
This great naturalist saw and described them for the first time.
The mechanism of forming a Penitentes is quite complicated, due to many factors: the melting
process of the ice here and sublimation there making the ice surface uneven.
The wind accelerates the difference, making the ice surface more and more concave.
The uneven solar radiation reflected on the concave-convex surface promotes the difference
to the maximum, making this place a deep bottom with a sharp peak at the other place, and
gradually forming a Penitentes.
Number 4: Solar storm
A solar storm or solar wind is a stream of
charged particles released from the upper atmosphere of stars.
Solar storms are responsible for magnetic storms and are directly related to the aurora
phenomenon of the Earth and on other planets.
As solar storms reach the Earth, the magnetic field can change its shape to form a process
called a geomagnetic storm, which affects electronic devices.
In 1859, a huge solar wind approached the Earth, causing some telecom poles and rails
to spark, creating aurora phenomenon in areas such as Havana, Cuba.
This phenomenon was observed and recorded, which was later called Carrington event.
In 1989, the solar wind landed on Earth and also caused Quebec and northeastern America
to lose power for 9 hours.
The Solar Storm also greatly affects the health of people.
During the period of strong storms, people with cardiovascular disease, high blood pressure
are at risk of having a heart attack, stroke, hypertension, etc.
Number 3: Volcanic lightning
Have you ever asked, "what would happen if
two of the worst phenomena of nature encounter with each other?"
In fact, this phenomenon paints a masterpiece of art that could be no more wonderful.
Scientists still do not have a satisfactory answer to this strange reunion.
The most plausible explanations are that the positively charged ejecta was released to
the outside and had been energized quickly, so they fired up into lightning bolts with
the intensity of thousands of volts.
To get these photos, the photographers had to be extremely brave.
What a true passion when they even dare to exchange their lives, guys!
Number 2: Whirlpool
Whirlpools are a natural phenomenon occurred
when the two opposing currents meet and curl, often found in narrow straits with large amounts
of accumulated water due to tidal forces.
With its suction, the whirlpool can wash away nearby objects and sink them into the water,
especially people or ships.
Because of that terrifying power, the whirlpool has become the inspiration for many adventure
movies.
In reality, scientists from Switzerland and the United States have also discovered many
large whirlpools in the Atlantic Ocean.
These gigantic ocean whirlpools are surrounded by dense swirling currents, making everything
sucked in unable to escape.
These "ocean black holes" exist for a long time, constantly moving seasonally and have
an area of up to 260 square kilometers.
Number 1: Supercell And this is the answer to the "Ask and Answer".
If mankind has a superman, then in nature, the supercell is the most terrible natural
phenomenon where the air-water flows from the bottom during a big thunderstorm.
They can appear anywhere in the world, lasting 2-3 hours, sometimes split into two storms
with opposite directions.
Super-thunderstorms often produce hail, or heavy showers, strong winds, and when directed
downwards, they bring large ice cubes.
The biggest thunderstorm known is the super thunderstorm Derecho.
In 2012, a massive and fierce system of "super thunderstorm Derecho" formed from storms and
strong winds, leaving a trail of destruction across the Midwest and Mid Atlantic, though
it rarely happened in the Atlantic.
Because of this phenomenon, the state of Virginia experienced a huge electricity cut.
The cable was broken while trucks crashed and 13 people were killed.
