Well, the horizon is just where the sky and earth APPEAR to meet. So it's kinda your decision... :)
In a small boat, it keeps the boat on a straight line. The fixed point on the horizon does not move. The boat does. If the boat moves toward a fixed point on the horizon, it is moving in a straight line. On any watercraft, watching the horizon also helps to prevent the visual disturbances that cause seasickness.
horizon came first because the horizon runs in a line along the sky, which really is an optical illusion to us, so people in ancient times would think the horizon was a straight line sideways hence the word horizontal
The western horizon.
There are three syllables in horizon.
The horizon line in a photograph is where the sky meets the land or water. It is often used as a reference point for determining composition and balance in a photo. Placing the horizon line higher can emphasize the sky, while placing it lower can emphasize the foreground.
A photograph can be broken into three equal sections: the top, center and bottom. The horizontal "lines" that break the photograph into three sections are important to landscape photography. (See the article Rule of Thirds for more information.) For the best landscape photograph, compose the photograph so the horizon falls on one of the lines - either the top or the bottom.

I would claim that a straight line is slightly bend as we define straight from the horizon.

To capture the perfect sunset photograph, choose a good location with a clear view of the horizon, use a tripod to keep your camera steady, adjust your camera settings for the right exposure, and consider using filters to enhance the colors. Experiment with composition and timing to capture the most stunning moments of the sunset.
Keep a weather eye on the horizon means to watch the horizon or as far as you can look for ships=water, people=land or water, or an animal=land or water.
The radio-path horizon distance exceeds the geometric horizon because radio waves can bend or be refracted by the Earth's atmosphere, allowing them to travel further than what is possible in a straight line. This bending effect enables radio signals to reach beyond the line of sight, extending the distance they can cover compared to the straight-line geometric horizon.
To keep a photograph safe and secure, store it in a protective sleeve or frame, keep it away from direct sunlight and moisture, and make digital backups to prevent loss or damage.
A photograph can be used to keep a special memory, remember a happy occasion (birthday, graduation, wedding) or it can be used as evidence in a crime.
You keep the rudder straight.
If you mean straight down, you would be near the equator.
