Water from the Earth's surface evaporates into the air, usually upon exposure to sun light. When the water vapor reaches the upper atmosphere, it cools from a vapor (gas) into small liquid droplets. When they become heavy enough by merging together, usually within clouds, they fall back to Earth as rain.

Rain is caused by water atoms evaporing, turning from a liquid into a gas through heat. Those gas particles condense into clouds. When the clouds become too dense the water atoms, which have then reverted back to a liquid state, fall from the cloud. The same idea is true for snow.
