The last line references the idea of being enslaved and brought down to the constraints of the sea as a metaphor for being controlled and restricted by external forces, represented by the chains and silver coins on the horizon in the poem "Omeros."
Yes. The shadows vary with how high above the horizon the Sun is. Close to the horizon = long shadows. Straight above = short shadow. Your powers of observation will show you that they do. Continuously.
At dawn and dusk, your shadows extend all the way to the horizon.
The sun stays closer to the horizon, which makes the shadows longer.
The longest shadows are cast when the sun is low above the horizon - either after dawn and before dusk.
Shadows appear tallest in the morning because the sun is low on the horizon, casting longer shadows due to the angle of sunlight. As the day progresses, the sun rises higher, reducing the length of shadows.
This phrase means the sun is setting- it is becoming late afternoon or evening time. ( Shadows lengthen as the sun moves gets closer to the horizon . )
When the sun's the closest to the horizon (so every dusk & dawn), and that would be the winter solstice.
At sunrise and sunset, shadows are longest because the sun is low on the horizon. As the sun rises or sets, the light is more spread out, leading to elongated shadows. This effect is due to the angle of the sun's rays hitting the Earth's surface.
Shadows change length during the day because as the earth rotates on its axis, the angle between the sun and any given point on the earth changes.
Shadows change length throughout the year because the altitude of the Sun above the horizon changes. The altitude (height above the horizon) of the Sun changes as the Earth revolves around the Sun each year. This is due to Earth's axis being at an angle. In the Northern Hemisphere, the North Pole is pointing away from the Sun on the winter solstice (around Dec. 21) and for the Northern Hemisphere the Sun is at its lowest altitude and shadows will be the longest of the year. On summer solstice (June 21), the Sun is at its highest altitude and shadows are the shortest of the year. Janice VanCleave
The lower the Sun is on the horizon, the longer the shadow that is cast, the higher the Sun is in the sky, the shorter the shadow.
So long as the sun is the same height above the horizon your shadows will be the same length whether it is morning or evening.
