How are Clouds Formed?, Water, Class 6 Science Video Lecture

hmm an alligator a sock that one looks
like a rat have you ever looked up in
the sky and seen shapes in the clouds
clouds can be big and fluffy like a
castle made of cotton candy or they can
be thin and wispy like little white
lines drawn in the sky but have you ever
wondered what the clouds are we know
there aren't real alligators or socks up
there but what makes a cloud a cloud
well they might not look like it but
clouds are just big clumps of water
droplets but how did those water
droplets get up there in the first place
water can exist in three different forms
a solid a liquid or a gas ice is just a
solid form of water and water in your
drinking glass is a liquid and you can't
see water when it's a gas which is
called water vapor but have you ever
heated a pot of water and notice that as
it boils the water level goes down the
water that's not there anymore has
evaporated or turned into gas it's
become a water vapor and floated up into
the air and that's basically how clouds
are made when the Sun shines down on the
water in oceans lakes and rivers it
actually pretty much the same way as
that pot on the stove it warms the water
enough to turn a little bit of that
liquid water into water vapor then the
water vapor rises into the sky and as it
goes higher the air gets colder
finally it cools down enough that it
turns back into a liquid again but this
time it sticks to tiny bits of things
floating around up there like dust dirt
and smoke as more water vapor float up
and bumps into those sticky wet specks
the droplets get bigger and bigger until
they're big enough to see now they have
formed clouds even though all clouds are
made of the same stuff they can look
pretty different there are actually
different kinds of clouds that
scientists look for based on how they
look and the type of weather that they
produce so let's play cloud spotter
again but this time with science first
we'll check out everyone's favorite the
cumulus cloud we love these guys because
they're the big puffy fluffy clouds that
can make us think of alligators or socks
or robotic rats they're usually bright
white and they're thick and dense enough
that when one passes in front of the Sun
it can cast a shadow
these clouds usually mean nice weather
but beware when you start to see a
cumulus cloud grow tall and turn dark
gray it can produce a big storm with
lots of thunder lightning and pouring
rain cirrus clouds are totally different
there's a super theme
wispy clouds hi this guy if a seers
cloud passes in front of the Sun you'll
hardly notice they're almost see-through
when you see these kinds of clouds in
the sky you're probably in for a nice
sunny day now take a look at these
stratus clouds they form something that
looks kind of like a blanket across a
big chunk of the sky they might look
flat and smooth or they may have a
pattern that looks bumpy or wavy stratus
clouds tend to block out a lot of the
sun's light so these clouds usually
bring a gray drizzly day but cumulus
Sears and stratus clouds are just the
beginning there are lots of different
versions of these three main types
depending on how high in the sky the
clouds form and the shapes that they
make you can be a cloud spotter too you
have a chance to check out cool clouds
every time you step outside so keep
looking up and pretty soon you'll be a
pro I telling you serious from your
Stratus as for squeeks and me we're
going to get back to these cumulus
clouds I think that one looks like the
giant squid thanks for joining us on
