Other forms: horizons
The horizon is the far line where the sky seems to touch the land or sea. On the horizon, a distant horizon, broaden your horizons.
For somebody standing on a beach it is about five kilometres away, and it moves back as you climb — which is why lookouts went up masts. Broaden your horizons is the standard figurative use. Note that the Greek means the bounding circle, from horos, a boundary.
