If we watch Sun Moon Set over a video recording , mostly, it's motion is never perpendicular to the Horizone , but at an angel other than 90 with horoizon. Is this related with Axial tilt of earh and our location ?Does , on equator , the "Settings" occur at right angle everyday ?

Since the earth's axis is tilted, the sun does not travel in a straight line across the sky, and neither do the planets. They follow a line called "The Ecliptic" which is north of the earth's equator during the northern summer and below it in the northern winter. It is this tilt that causes our seasons, not the fact that the earth is closer to the sun during part of it's elliptical orbit.At the equator the sun is directly overhead only twice a year during the equinoxes.
