Detailed explanation-1: -This is also called a prograde rotation. Because of this direction of rotation, we see the sun rising every day in the east and setting in the west.
Detailed explanation-2: -From Earth, the Sun looks like it moves across the sky in the daytime and appears to disappear at night. This is because the Earth is spinning towards the east. The Earth spins about its axis, an imaginary line that runs through the middle of the Earth between the North and South poles.
Detailed explanation-3: -At the fall equinox, the Sun rises due east and sets due west. It continues on it’s journey southward until, at the winter solstice, the Sun rises are far to the south as it ever does, and sets as far to the southwest. Many, if not most, prehistoric cultures tracked these rising and settings points with great detail.
Detailed explanation-4: -The Earth spins on its axis from west to east. The Coriolis force, therefore, acts in a north-south direction. The Coriolis force is zero at the Equator.
Detailed explanation-5: -Our star, the Sun, revolves anti-clockwise. So, our Earth also rotates anti-clockwise when looked from the north-pole. As a result, the earth rotates from west to east. So, the sun rises in the east and sets in the west.
