Answer 2

Advanced sunrise and delayed sunset The sunrise is advanced due to atmospheric refraction of sunlight. An observer on the earth sees the sun two minutes before the sun reaches the horizon. A ray of sunlight entering the earth's atmosphere follows a curved path due to atmosphere refraction before reaching the earth.
