The sun
stays in its position at the center of our solar system. It appears
to rise and set due to the Earth's rotation. The Earth rotates on its
axis and makes one complete turn every 24 hours. It turns toward the
east.
As the
Earth rotates, different locations on Earth pass through the sun's light.
The photos show how that looks every hour. As your town (or Africa,
in these photos) turns toward the sun and begins to enter its light,
the sun appears to rise; as your town begins to leave the sun's light
and enter darkness, it appears to set.
Does this
help explain why the sun seems to rise in the east and set in the west?
