The sun's apparent motion across the sky from East to West daily is due to the
A) rotation of the sun.
B) rotation of the earth.
C) orbit of the earth around the sun.
D) orbit of the sun around the earth.
I think the answer would be c.
the orbit around the sun takes a long time. The sun's rise-fall happens every day.
So it is D?
NO - Try B
The earth spins around completely every day, making the sun (in the sky) appear to go around from east to west! Geez.
Sorry! Gosh you don't have to be that mean.
Sorry. I just get annoyed when I see someone just guessing, with no apparent thought involved. Of all the possible answers, D is the most absurd, since the sun does not orbit the earth.
You are correct! The sun's apparent motion across the sky from East to West daily is due to the rotation of the Earth, so the correct answer is B) rotation of the Earth.
To understand why this is the case, we need to know that the Earth rotates on its axis, which is an imaginary line passing through the North and South Poles. This rotation takes approximately 24 hours to complete, causing the sun to appear to move across the sky from East to West.
As the Earth rotates, different parts of its surface come into and move out of the sun's direct light, resulting in the cycle of day and night. The side of the Earth facing the sun experiences daylight, while the opposite side experiences darkness, creating the illusion of the sun moving across the sky.
On the other hand, the Earth's orbit around the sun, mentioned in option C, is responsible for the apparent motion of the sun throughout the year, leading to changes in the angle and duration of daylight. So, while it does affect the sun's position in the sky, it is not the primary reason for its daily motion.
