​

Answer 1

Answer:

Explanation:

We get day and night because the Earth spins (or rotates) on an imaginary line called its axis and different parts of the planet are facing towards the Sun or away from it.

Answer 2

Answer:

Day or night, the Sun is fixed at its place in the solar system. It is the Earth's rotation and spinning that makes the Sun disappear at night. ... The Earth keeps spinning and the Sun facing side later experiences evening and then night when that side has moved away from the Sun.
