1Q)
What is the reason of formation of days and nights?
2Q)
Why is the actual distance reduced on map?

Answer 1

1Q)The Earth orbits the sun once every 365 days and rotates about its axis once every 24 hours. Day and night are due to the Earth rotating on its axis, not its orbiting around the sun. The term 'one day' is determined by the time the Earth takes to rotate once on its axis and includes both day time and night time.

2Q)The actual distance on the ground is reduced on the map because the distance that is covered on the ground is larger than a piece of paper. It is not possible to be exact in the distance on the paper that leaves the only option of reducing the distance between a location on the map.
