Answer 1

$\Huge\mathcal\blue{\underbrace{\overbrace{\mid{\red{Answer}}\mid}}}$

We have day and night because the Earth rotates. It spins on its axis, which is an imaginary line passing through the North and South Poles. The Earth spins slowly all the time, but we don't feel any movement because it turns smoothly and at the same speed.

Answer 2

Answer:

Hope it will help you mate

Explanation:

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.
