I'm uneducated about this, and my answer may be completely wrong. Logically, however, I would guess that it is due to the speed of both the rotation and the sidereal motion of the earth. For a few moments, the sun's rays pass through and refract towards the observer at the proper angle to view a rainbow. Of course, this is given the atmospheric conditions are conducive to the rainbow itself. Therefore, one must factor in the movement and density of the moisture and wind in the atmosphere. The speed of rotation of the earth is about 1,001 mph and the sidreal speed is about 6,700 mph. The rainbow appears and fades as the optimum angle for the viewer given the atmospheric conditions passes. This brings to my mind a curious question: do rainbows appear on other planets, and if so, what atmospheric conditions allow them? For example, Venus has a thick cloud layer-is it then possible that one might observe a rainbow or something like it, if one were to stand on that planet? And, what about auroras, which are caused by solar emissions passing through the magnetic sphere of the earth?
