How are water sheds connected to the water cycle?

When water enters the watershed as rain or snow, it is called precipitation. Trees and plants use much of the precipitation and then release it back into the air as water vapor. This continuous movement of water from the air to a watershed and back to the air is called the water cycle.

Watershed... the word means a parting, a shedding of waters. But a watershed is a gathering place, also. It is a place where hills and plains and people's lives are connected by falling rain and flowing water. A watershed is measured by the hilltops and ridges that are its boundaries.
