the first one is water cycle the lithosphere is the outer part of the earth consisting of the crust an upper mantle and then there is the atmosphere which contained gases surrounding the earth so in between the atmosphere and the letters fair water circulates through the water cycle now you must be thinking what is the use of water cycle well it is because of water cycle all living organisms are able to maintain life because every form of life on Earth depends on water in the form of solid liquid or gas let me tell you the entire
process of the water cycle in brief in the first stage the Sun warms the water from the ocean lakes ice and soil when the water is warm it rises into the air and turns into water vapour this is called evaporation where the liquid water is converted into water vapour which is in gaseous form the next step is condensation water vapor rises up in the atmosphere at high altitude the temperature is very low because of that the water vapour changes into very tiny particles of ice or water droplets when these tiny particles of ice or water
droplet come close together they form clouds the third step is precipitation when ice and water droplet turns into clouds now you have to understand that these clouds move all around the globe and they also grow in size actually when the size is increasing there will be a lot of water droplets inside there will be a time when the cloud becomes too heavy to hold these water droplets that's when it falls back on earth in the form of rain and snow in the fourth and final step the water from the rain and snow flows back into
the ocean through rivers lakes and streams so this is the water cycle in brief
