The apparent shift in the position of the sun during sunrise and sunset is due to atmospheric refraction.

Answer:

It's due to atmospheric refraction.

Explanation:

with altitude (height),the density & hence refractive index of air layers decreases .Light rays starting from the sun travel from rarer to denser layers. They bend more &more towards normal .

however,an observer sees an object in direction of the rays reaching her/his eyes. So to observer,the sun appears above the horizon. Apparent shift is by 0.5°.

That's why the sun appears to rise early by about 2 minutes & appears to set late by about 2 minutes.
