water evaporates from oceans and forms clouds
these clouds are blown inland
as they meet land they meet mountains which make them rise
as they rise they become cooler and condense into a liquid
this falls as rain

rain (water) forms clouds using the rising hot air explanation. AS the water vapor on the earth surface is heated and rises, it settles into the atmosphere. Once the rate of condensation (dewpoint temp) exceeds the rate of evaporation (air temperature), clouds form.

If the earth's surface is heated, the air above it is also heated and this warm air rises due to bouyancy as the warm air is lighter than cold air.If this rising air contains enough moisture, it cannot hold the moisture after a certain height as it is continuosly becoming colder and colder.Condensation (water vapour becoming water) takes place and the lighter,invisible water vapour becomes tiny,visible water droplets attaching itself to tiny dust particles which are available in the atmosphere in plenty.
These are very tiny droplets and have negligible weight and so they all float in the air in the form of clouds.Sometimes ,due to some triggering mechanism the water droplets join together to form a bigger droplet and gain weight.Due to this they start falling as rain.

As air heats, it rises. As this heated air rises, it cools down which makes it condensate (make water droplets). When the cloud is full enough of these water droplets, the rain will drop out of the cloud.

rain forms from the humidity and the moisture in the air.

clouds are made from water vapor. when ever water is heated it evaporates and froms into water vapor. the water vapor then gathers in the sky and whenever enough has come together, it starts to rain as water again. thats the water cycle:evaporation,condensation,precipitation, then accumalation.
