Hi! I am a H20 Droplet. I will be guiding you through the process of the hydrologic Cycle. So here we have the sun heating me up in the sun.
When the sun heats the sea water surface, I absorb thermal energy making me warm up and start to vibrate. It turns me into water vapor or gas and floats me up to the sky. This change from a liquid to a gas is called Evaporation. Also There is something called transpiration. It happens in the leaf atmoshpere . When the plant opens it stomata to let in carbon dioxide transpiration happens
As I am floating up as water vapor through the troposphere in the atmosphere, it starts getting cooler. I and other H2O droplets start to lose so much thermal energy that we change from a gas to a liquid state. When millions of drops come together we form clouds like the ones above me. Now I'm a cloud not an H2O droplet anymore. This is called Condensation.
In time, the drops of water like me that are in the clouds become so large and heavy that they fall down to Earth's surface and the Earth's gravity helps pull me back to Earth in different forms. I will normally fall as rain but if its colder, I will be sleet, hail or snow. This is called Precipitation
I have just landed in a river and will slowly drift out to the ocean through a process called runoff. Earth's gravity affects runoff as the water tends to flow to the lowest elevation and fall into the sea. I could have also landed on the land and would have seeped through the ground and slowly but surely make my way back to the sea underground. I could have landed directly into the salty oceans too.
I am back at the start of my water cycle journey, in the ocean and getting ready to repeat this cycle again and again
