“Ahhh.. It's raining”
-
Hey! Have you ever wondered where the rain comes from?”
-
Or how the clouds are formed?
-
Well, this is what the water cycle is all about.
-
Come let's explore!
-
Zoooom In
-
When the sun heats up the rivers and oceans, water becomes water vapour and it rises up in the air.
-
This process is called evaporation.
-
It is the first step of the water cycle.
-
You too can see water vapour at home!
-
Just tell your mommy to heat some water.
-
And as the water gets heated, you'll be able to see the water vapour rising up in the air.
-
When the water vapour reaches up in the sky, it turns into tiny droplets of water.
-
These water droplets along with various gases and dust particles, come together to form clouds.
-
This is known as condensation.
-
Now, hold a cold lid over the vessel in which you heated water.
-
When you open the lid after sometime, you'll be able to see water droplets on the lid.
-
That's exactly what condensation is!
-
When the cloud becomes too heavy and it cannot hold any more water inside,
-
it bursts open to give out rain, hail or snow.
-
This is known as precipitation.
-
As it rains, water gets collected in oceans, lakes and rivers.
-
It even seeps through the soil and becomes ground water.
-
Thus water cycle is a continuous process of
-
evaporation, condensation and precipitation.
-
Did you know that even plants sweat?
-
That's called transpiration.
-
That's why it rains more in places with more trees,
-
like hill stations and forests.
-
Sometimes snow directly turns into water vapour
-
without melting into water.
-
That's called sublimation.
-
This happens a lot in cold countries.
-
Oh, I need to run now.
-
It's raining again.
-
So this is me zooming out, tune in next time for more fun facts.
