L8 : Rainfall: Floods and Drought - Water Part, Science, Class 6 Video Lecture

hello friends this video on waterpark 8
is brought to you by example.com no more
fear from example so now that we have
spoken so much about the water cycle it
becomes important to talk about
rainwater now green one please a very
crucial especially in the filling India
so here it is important because
agriculture is largely dependent on
hands now as I mentioned before that
quite a departure to take things for the
crops to get cultivated properly they
need to be watered
correct that means water need to be
given to the plants so in India we
largely depend on rainfall so that our
fields that water that agriculture is
dependent on rain
so if there is moving there will be no
offical till Eclipse so independence so
then you are getting source to yourself
like another importance of faith from
use that feels ready those latex
revolutions and we need water for so
many buttress is no dating right so if
they are filled it up with water so that
will be better for us support sunlight
box supports all life forms as I said
what it is important for all life forms
now men these same fulfills their water
bodies agree will sleep solutions it
also supports a huge number of aquatic
life and we become can users which lead
in these water bottles
so that means rainfall is very very
important now when we talk about
rainfall
what becomes more important to discuss
is that sometimes there is excess of
paper sometimes there is no rainfall at
all now both of these situations are not
very not good to have situations so
rainfall can cause problems luckily this
more rainfall at all that can result in
a drought if it is too much of rainfall
that can resultant flux and in both of
these cases are huge damage to life and
property takes place so when there is a
plug there is so much of water
everywhere
buildings collapse there is loss of
property organisms died lot of huge loss
of life as well similarly when it when
the justice reverse scenario happens
that there is no rainfall at all in that
case there is a very very to an effect
effect on the agriculture so we do not
have enough crops so when there is not
enough crops we do not have enough food
to eat so that is also a lot of people
die out of hunger a lot of diseases
spread out you can grout to lack of
rainfall also impacts us excessive
rainfall also impacts us now let us
quickly look at the problems that can
happen due to instance of rainfall that
is flood and its harmful effects as a
result of floods there could be soil
erosion what is soil erosion category of
the upper layer of soil by water it's so
much of what it is flowing over there
shall face what happened since the top
layer of soil is being carried away by
the water so top layers of soil are
patent away with water so what happens
as a result of this now the top layers
of soil and comparatively move for Danny
so the four time layers are carried away
that means the soil which you are left
with is no no more than four times so
they will no support the root of plants
so that the soil erosion is a bad thing
to happen secondly destroyed forest
ecosystem let me cite the corners we
have huge remove trees we have future
with animals insects birds and so many
organisms which are mutually within in
the future but do you plant the trees
category like a water the entire
vegetation is flying so your animals
dying so in the end how an ecosystem
within the forest is destroyed complete
loss of property because huge will be
whose offices everything get broken
daily gets carried away when water crop
yields and
and say it we felt it pretty quick I do
we need water but if you put too much of
water than they ever get you can feel
also that what happens if they die it
drops or the clamps they go completely
underwater
so even with excess of water it ends
what are we locking then the plants also
tend to try religious towns and cities
destroyed the invalid establishment of
humans get affected lots of species in
your life so happens some species of
animals which are already there may be a
few of them in system even they die as a
result of flood and there we lose that
species forever or something - Adam
Schneider particular species of an
animal they recite in the wood filler
area and found only the vertical edge of
the implication but duty love in that
location you ended up having all those
variables feel so as a result this will
lead to the loss of species so you might
ask here what is a species so species
refuse to a group of organisms that can
in turn so what do we mean by that let's
say we talk about dogs so they are
carrying multiple species of dogs so
those types of dogs which an individual
intending give rise to a new organism
are they and mutually made to give next
their young ones they are said to belong
to us the scalar species so group of
organisms which can integrate amongst
themselves so we can say that X again is
attack dog solutions definitely know
this may lead to similar types of
animals fall under the category were
same species
now let us look at streets value that is
the army vet drought so in this case
what route water level will get lowered
because it's more rainfall since already
know okay so moving one that will smooth
ground water because groundwater Donis
moves around what is the name for a
little food in one round water level
will get lower so you can understand
their side try to dig below the surface
of the earth in an area which gives
sufficient rainfall and try to do the
same activity in love which did not
receive rainfall for a couple of months
in the past so like you will know the
difference
so the first a square there is
sufficiently when you'll see that very
quickly you will lose that 11 ready to
be able to water rather than say in case
that is increase of and really moving
for the last few months you will see
that collectively need to dig a lot to
reach a level where there is water and
sometimes it might be diminishing can be
so severe that you keep on digging it
but you do not get trails of any water
this to our forest system so that there
will be no water settles we'll all be
dry as I said the glance will also cry
up plants will values valuables which
they will also guide to then IQ system
really will get spoiled water level
decreases in water bottles in born
sleeves and labels sometimes due to
drought they might even dry out
completely you do not see it in the
water bottles that is going so I think
saying that maybe water class then water
gets to between the swipe patterns now
my name is moving one at all it's
obvious
there is water that is actually into
this white that is why in the wheels
drive new rock regulation in slack of
humans because it is going to be
depending on green one it's not extinct
so I did is moving one at all for a long
time and that is the rock that equation
will get and we're asleep and there will
be trotted off so what can isn't
remotely understand right so we see that
good floods and droughts out there
things and that is when it is a
important back rate for a transcript at
they write water so it shouldn't be so
so now that we saw that waiting what if
it happens in excess and is it
disastrous in the form of flood
similarly if you doesn't happen at all
since long and it can be equally
disastrous before now as a result of
flooding drought who are the common
victims and witnesses so the common
victims are forests if you look at the
animals living in the forest the birds
insects even the tiny organisms the
plants all these life forms are
adversely impacted as a result of flood
and drought so that is why it is saying
that it is very important to making the
right amount of water on this earth
because what it is something which is
very very gracious very very useful for
the survival of all life forms thank you
