We say it is 'rising,' but this is apparent motion, and not true motion. The same is true for the rising and setting of the moon and fixed stars.
There is another spectacular example of apparent motion that is different from true motion. Because the moon 'rises' in the east and 'sets' in the west, it is easy to think that it is "moving" from east to west. In fact, the moon's orbit around the earth is from west to east. The slow (monthly) orbit of the moon along with the 24-hour rotation of the earth give us the impression of the moon's apparent motion.
We say that it sets.
risen or set
Possibly you might say good morning.
When the sun sets over the horizon, we say that the day is coming to a close or that night is falling.
Sunset. Evening/night time begins.
I call it sunrise
The sun rises in the east.
The sun rose gently over the eastern horizon.
I gazed out at the horizon and watched the sun disappear beneath it. The ship sailed toward the horizon, fading into the distance. The mountains on the horizon looked majestic in the evening light.
The horizon is the furthest point the eye can see. The sun rises over the horizon because as the earth turns, the sun gradually comes in to view as the side of the earth we're on turns towards it. The sun isn't really rising - we're simply moving. It's like if you slowly turn to look at something, it doesn't magically appear in front of you, it comes in to sight, and as you turn it comes more and more into your vision.
The land or ocean features would vary depending upon where you are, but one could safely say it rises over the eastern horizon.
The western horizon.
