The nightly motion of objects across our the sky from horizon to horizon is caused by

A)rotation of the Earth on its axis

B)revolution of the Earth around the Sun

C)the motion of the solar system around the galaxy.

D)rotation of the whole celestial sphere of stars around the fixed Earth.The nightly motion of objects across our the sky from horizon to horizon is caused by ?A) Rotation of the Earth on its axis.



Over the course of a day, the Earth rotates once about its axis. During the roughly 12-hour period that any one object in the sky is visible, any such object's motion relative to the Earth is negligible. Therefore, the object's apparent motion over the course of a night is due almost exclusively to the Earth's rotation.



However, the gradual, cyclical change in an object's position over the course of a year is due to the revolution of the Earth around the Sun. This is why the Sun's path moves back and forth from the north to the south and why different stars are visible at different times of year. And the variability of the positions of the planets and the appearance of comets are due to the movements of those objects around the Sun. The relative positions of the stars in the night sky do change over time, because the stars are moving relative to the Solar System; however, relatively few stars are moving fast enough that their positions have changed noticeably since antiquity.The nightly motion of objects across our the sky from horizon to horizon is caused by ?It's (A).

Why do you even ask? You are schooled in those states that the only science is Bible?
