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
you are correct
The correct answer is B) rotation of the earth.
To understand why the sun appears to move from East to West daily, we need to understand the motion of the Earth. The Earth rotates on its axis, an imaginary line that passes through its geographic poles. This rotation takes approximately 24 hours to complete and is responsible for the alternation of day and night.
As the Earth spins on its axis, different parts of the Earth are exposed to the Sun's light, causing the apparent motion of the sun across the sky. When the Sun is on one side of the Earth, it is daytime for that part of the Earth. As the Earth rotates, the Sun gradually appears to move across the sky until it reaches the opposite side of the Earth, causing sunset.
Therefore, the daily motion of the sun from East to West is due to the rotation of the Earth on its axis.
