EVERYDAY SCIENCE

Detailed explanation-1: -We see the sunrise and sunset because of Earth’s rotation about its own axis . Earth is rotating about its own axis from West to East. So, when seen from the Earth, the Sun appears to rise in the East and set in the West.

Detailed explanation-2: -The Earth rotates from West to East. So, when observed from the Earth, the Sun always appears to be rising on the eastern horizon and setting on the western horizon.

Detailed explanation-3: -The Sun rises and sets exactly due east and west only when the circular path of our turn on Earth’s surface splits into two equal parts, half in the light and half in the dark. As our planet’s rotation axis tilts by 23.5° with respect to its orbital plane, this alignment happens only at the spring and fall equinoxes.

Detailed explanation-4: -The March 2023 equinox happens on March 20, 2023, at 21:24 UTC (4:24 p.m. CDT). The March equinox heralds the arrival of spring in the Northern Hemisphere and autumn in the Southern Hemisphere. As a matter of fact, on this day, the sun rises due east and sets due west.

Detailed explanation-5: -The Sun spins or rotates on its axis in the same direction as Earth (counterclockwise, when looking down from the north pole). Because it is a gas, it does not rotate like a solid. Different sections rotate at different speeds! The Sun actually spins faster at its equator than at its poles.
