In what direction is the apparent daily motion of the sun?
It is westwards.
What is the line that the sun traces across the celestial sphere?
The "ecliptic". In truth, the Sun doesn't move; the apparent motion of the Sun across the sky is caused by the Earth spinning, and the apparent motion of the Sun across the "celestial sphere" is caused by the Earth orbiting the Sun. But the plane of the Earth's orbit around the Sun is what causes the apparent motion of the Sun across the celestial sphere, so the "ecliptic" is actually the plane of the Earth's orbit.
What direction does the sun rises and set?
the sun rises in the east and sets in the west. by leanne marriott x
What does the length of shadows made by the Sun throughout the day tell you about the Suns apparent motion across the sky?
If the shadows are longer, that means the Sun is lower in the sky.
Compare apparent motion with actual motion?
Apparent motion is what it looks like it's doing from here on earth. Actual motion is what it's actually doing in space relative to the system's center, whether you're talking about the sun, if it's the motion of a planet; or the galactic center, if you're talking about a star.
Why there are seasons and the apparent motion of the stars and sun?
The seasons are due to axial tilts of planets and the apparent motion of stars and sun on the celestial sphere is due to diurnal motion.

In what direction is the sun's annual motion relative to the fixed stars?
The Sun's apparent motion among the stars is from West to East - just like the motion of the Moon, and the predominant motion of the planets (planets sometimes go from East to West, too - in this case they are said to be retrograde).
In witch direction does the sun rises?
The sun rises in the east and sets in the west. This is, of course, apparent motion and not true motion.

What will happen if the sun stands still?
A:To the ancients, it seemed easy for supernatural powers to make the sun stand still for a few hours, with no adverse outcome. However the apparent motion of the sun across our sky does not mean the sun is actually moving relative to us. This apparent motion is caused by the rotation of the earth, which can not be stopped.
What does the length of shadows made by the Sun throughout the day tell you about the Suns apparent motion across the sky?
If the shadows are longer, that means the Sun is lower in the sky.
What do we say when the sun goes down over the horizon?
We say that it is 'setting,' 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.
When does a planet is said to be in retrograde motion?
A planet is said to be in retrograde motion when its apparent motion - the motion as seen by us, against the background stars - is from east to west.Planets spend more time in prograde motion, from west to east. The apparent movement of Sun and Moon against the background stars is also from west to east. Not to be confused with the daily motion, due to Earth's rotation.
What causes the apparant movement of stars in the sky?
The real motion of stars is hardly noticeable even over a period of many years. It's the Earth's daily rotation the is the main cause of their apparent motion. (Stars are so far away that the Earth's revolution around the Sun hardly cases any apparent motion.)
What is a star's apparent shift in motion called?
Motion parallax.
