The sun
Water vapor cools and becomes a liquid

water cycle
slower moving water, lakes, ponds, rivers and still water
lentic water
Faster water like streams and rivers, flowing water
lotic water
Water that moves across the land surface and into streams and rivers
runoff

What is a body of air that has about the same temperature throughout?
air mass

When warm and cold air masses meet. They usually don't move, possibly causing rain for many days.
Stationary front
Rain, snow, sleet, hail that falls to the ground
precipitation
Precipitation that falls when the temperature is BELOW freezing
snow
