Before rain can occur clouds have to form that occurs when the dew point reaches the LCL (lifting condensation level) producing clouds thats the beginning of the process. The scientific name and explanation of how rain forms is called the Bergeron Process. Rain will grow large enough to fall and hit other rain droplets on the way down and grow larger this is called collision coalescence process. When clouds can no longer hold the rain it falls and because of friction (air) if breaks up in to different sizes between 1-5 mm. Drizzle and mist is smaller then that Drizzle is from about .5mm-.9mm and mist is smaller then .5mm.

Sunlight or heat itself boils water into water vapor. This is taken high in the sky by raising air currents

Once it gets really high, it cools (because at higher altitudes lower temperatures, because there is less air, because it concentrates near the earth's surface because of gravity) and turns into groups of droplets called clouds that are little enough to be suspended in the thin air.

When the quantity of droplets turns critical, these start to join together and form drops, which are no more able to be suspended in the thin air so they fall to the surface, making the phenomenon known as rain.

This is just a description I made from my knowledge and I don't know if it is 100% correct

basically the clouds nad the atmosphere and stuff gets too full of moisture and the clouds have to release the moisture. they do that by making it rain because the vapor becomes a liquid and it falls from the clouds.


The water cycle has no starting or ending point. The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. Ice and snow can sublimate directly into water vapor. Rising air currents take the vapor up into the atmosphere, along with water from evapotranspiration, which is water transpired from plants and evaporated from the soil. The vapor rises into the air where cooler temperatures cause it to condense into clouds. Air currents move clouds around the globe, cloud particles collide, grow, and fall out of the sky as precipitation. Some precipitation falls as snow and can accumulate as ice caps and glaciers, which can store frozen water for thousands of years. Snowpacks in warmer climates often thaw and melt when spring arrives, and the melted water flows overland as snowmelt. Most precipitation falls back into the oceans or onto land, where, due to gravity, the precipitation flows over the ground as surface runoff. A portion of runoff enters rivers in valleys in the landscape, with streamflow moving water towards the oceans. Runoff, and ground-water seepage, accumulate and are stored as freshwater in lakes. Not all runoff flows into rivers. Much of it soaks into the ground as infiltration. Some water infiltrates deep into the ground and replenishes aquifers (saturated subsurface rock), which store huge amounts of freshwater for long periods of time. Some infiltration stays close to the land surface and can seep back into surface-water bodies (and the ocean) as ground-water discharge, and some ground water finds openings in the land surface and emerges as freshwater springs. Over time, the water continues flowing, some to reenter the ocean, where the water cycle renews itself.

Clouds form when upward flowing air which cools by expansion can no longer contain all of the water vapour it holds.Some of the water vapour condenses into cloud droplets(or ice crystals,if the air is cold enough) forming a cloud.
The cloud has now two choices.It can re-evaporate into water vapour or the cloud particles can combine together to form precipitation which then falls to the ground.About one half evaporate into water vapour and the other half falls as preciitation.
