Good morning sir, good morning madam
I'm Vidhi
and we are going to present a model of melting of glaciers due to global warming.
as you can see that, this is the Sun
there are mainly 3 types of rays coming from the Sun
ultra violet rays, infrared rays and white light rays
ultra violet rays are very harmful to us and absorb by the ozon layer
infra red rays and white rays come towards the Earth
they have to pass through the layer of atmosphere
which is made up of different gases like
nitrogen, oxygen and other green house gases like
carbon dioxide methane etc.
when these rays pass through the layer of atmosphere
they can come in but can not go out
75% of100 are absorbed by the Earth
and 25% are reflected back to the sky
but
they are trapped
and the normal temperature of the Earth is maintained
but now these days there is much air pollution
and much gases are releasing
and the density of layer of atmosphere is increasing
and more rays are trapped inside
and the temperature of the Earth is increasing.
this increasing in the temperature due to gases
is called global warming
Now Fanil will speak
thank you
so with the help of this model
we want to create awareness for this major upcoming problem
of global warming
we are trying to convey that our Earth is crying
please stop air pollution
please save our Earth
and minimize this problem
otherwise it will dominate us and take our lives
Thank You
