Homework Statement

In the absence of an atmosphere, a star moves across the sky from horizon to horizon at a constant speed. how does the star appear to move in the presence of an atmosphere?

I would say that in the presence of an atmosphere the star don't move at all because of all the air and magnetic force. can someone tell if I'm right or wrong?

Stars are very far outside the Earth's atmosphere. They are not affected by it. The question is asking the atmosphere affects the light from the star.
