What is precipitation ?

Precipitation means falls of water , snow , solid , Iiquid state from clouds to ground .


70.8 % part of the earth's surface is full of water .  The distribution of this water is very uneven .
At , some places , the water storage is limited while it is ample at other places .
We see and experience the different forms of condensation .

These forms of condensation occur due to water vapour in the atmosphere .

As the atmospheric conditions change , we see changes in the forms of condensation .
On winter mornings , we find dew which are falled on leafed and all other objecta which were under sky at night .
In areas located at higher altitudes , snowfall occurs ;  while it rains in other places . 
Some places experience dense fog while some places experiences hailstones suddenly and face crop destruction . 


Rainfall  :-  1) We generally get water in the form of rainfall . 
2) The temperature of the air with water vapour reduces when it goes higher .
3) Condensation of the vapour occurs .
4) Clouds form when the condensed    water droplets and dust particles accumulates .
5)  The water droplets increase in size .
6)  When they cannot float in the air anymore because of their weight , they come down as rainfall .


Snow  :-  

1)  When the temperature in the atmosphere falls below the freezing point , water vapour directly turns into snowflakes . 
2)  This is called as sublimation .
3)  Here , the vapour in the form of gas transforms into solid snow .
4)  Precipitation in the form of solid particles of snow is known as snowfall .
5)  In high latitudinal and temperate region , snowfall occurs at the mean sea level while in tropical areas , snowfall occurs at the places located higher than the snowline altitude .
6) As the snow is in the solid form , it does not flow like water .
7)  Layers of snow get deposited .
8)  When the snow accumulates on a large-scale , then the transport and the communication system of that area collapses .
9)  People living in those regions have to protect themselves from frostbite .
10)  At last snow melts , the region gets water .

Co-ordination in Plants

      🌳    Co-ordination in Plants   🌳 Plants do not have systems like the nervous system or muscular system of animals .  Then , how do plants bring about movements ?  In plants , movements are mainly in the form of responses given to the stimuli . Movement or growth of any part of the plant in response to an external stimulus is called 'tropism' or 'tropic movements' . The shoot system of any plant responds to the light stimulus that is it grows towards the source of the light . The movements shown by plants towards the source of the light is called 'Phototropic Movement' . The root system of plants responds to stimuli like gravitation and water .  These responses are called 'gravitropic movements' and 'hydrotropic movement' resectively . Movement shown by plants in response to specific chemicals is called 'chemotropic movements' .  For example , the growth of the pollen tube towards the ovule . All the above - menti...

             ✊    Acupressure Points  👊 Our Body is full of a Complex System in that we have muscles , bones , blood and nerves , tissues . Our internal body parts are involuntary , and our external body parts are voluntary . We can't do exercise of our internal organs like brain , heart , liver , stomach , lungs , throats , hormonal glands and most of the internal organs . So we can do exercise by the connection of the nervous system by acupuncture the hands and legs and many other external parts . See this image for exercising internal organs  :-  By Acupuncturing all of the whole hand our internal exercise will be well done going on . Please do this for healthy health ....👍

Sonography

Sonography   What is Sonography ?  Sonography technology uses ultrasonic sound waves to generate images of internal organs of human body . This is useful in finding out the cause of swelling , infection , pain , etc . The condition of the heart , the state of the heart after a heart a heart attack as well as the growth of foetus inside the womb of a pregnant women are studied using this technique . This technique makes use of a probe and a gel . The gel is used to make proper contact between the skin and the probe so that the full capacity of the ultrasonic sound can be utilized . The gel is perfectly applied to the skin outside the internal organ to be studied . High frequency ultrasonic sound is transmitted inside the body with the help of the probe . The sound reflected from the internal organ is again collected by the probe and fed to a computer which generates the images of the internal organ . As , this method is painless , it is increasingly u...
