English: 
Aristotle Plato Socrates even Galileo
Galilei also asked insult answers and
today we still search
guess we have gotten too many answers
the mysteries of the universe will never
be fully known or discovered their ever
expanding and that keeps us asking we
will always search for something but
today we will answer one of the most
asked questions why is the sky

English: 
it's easy to see that we are under a big
blue sky but why blue
is a force bigger than us painting the
sky every day I will tell you
we've all looked at the Sun at some
point in our lives I know I know it's
bad for our eyes but we've all done it
it looks white doesn't it but guess what
it is actually made up of all the colors
of the rainbow
crazy right but trust me the light
contains seven colors red orange yellow
green blue indigo and violet
specifically in this quarter

when white light shines to a prison
the light is separated into all its
colors a prism is a specially shaped
crystal
the light you see is just one tiny bit
of all the kinds of light energy beaming
around the universe and around you light
energy passes through the ocean light
energy travels and waves to some light
travels in short choppy waves other
light travels in long lazy waves blue
light waves are shorter than red light
waves clouds on the other hand are made
of water droplets that are much larger
than the wavelengths of visible light
the way they scatter sunlight is

determined by how the light is refracted
and internally reflected by and
diffracted around the cloud droplets for
these particles the difference between
the scattering of blue and red light is
not really as large as it is for gas
molecules thus our eyes receive a
substantial amount of scattered light at
a visible wavelength causing clouds to
appear more white than blue especially
when viewed against a blue sky
background
sunlight reaches Earth's atmosphere and
is scattered in all directions by all
the gases and particles in the air blue

other colors because it travels at
shorter smaller waves this is why we see
a blue sky most of the time since
scattering by the atmosphere causes the
sky to be blue a planet with no
atmosphere cannot have a bright sky
for example photographs taken by the
Apollo astronauts on the moon show them
on the moon's surface bathed in sunlight
but a completely dark sky in all
directions away from the Sun it's scary
when it's dark
closer to the horizon the sky fades to a
lighter blue or white the sunlight
reaching us from low in the sky has
passed through even more air than the
sunlight reaching us from overhead as
the sunlight has passed through all this

English: 
air the air molecules have scattered and
re scattered the blue light many times
in many directions also the surface of
earth has reflected and scattered the
light all this scattering mixes the
colors together again
so we see more white and less blue
sometimes the whole western sky seems to
glow all mysterious
the sky appears red because small
particles of dust pollution or other
aerosols also scatter blue light leaving
more purely red and yellow light to go
through the atmosphere

I hope you understand now why the sky is
blue
but here's a question for you is the sky
blue on other planets to answer it all
depends on what's in the atmosphere for
example Mars has a very thin atmosphere
made mostly of carbon dioxide and filled
would find dust particles these fine
particles scattered light differently
than the gases and particles in Earth's

atmosphere photos from NASA's Rovers and
Landers on Mars have shown us that at
sunset there's actually the opposite of
what you'd experience on earth during
the daytime the Martian sky takes on an
orange or reddish color but as the Sun
sets the sky around the Sun begins to
take on a blue gray toe
so here are some important points from
the lesson if you want to study you can
do flashcards with them the sunlight
contains all of the rainbow colors the
light is reflected like in a prism
sometimes the whole western sky seems to
glow
no atmosphere means there will be no
coloring in the sky
