Answer:
From Earth, the Sun looks like it moves across the sky in the daytime and appears to disappear at night. This is because the Earth is spinning towards the east. The Earth spins about its axis, an imaginary line that runs through the middle of the Earth between the North and South poles.
Explanation:
As the Earth you’re living on spins once, the area in which you live moves into the light coming from the Sun (DAY), spins on and eventually moves out of the Sun’s light (NIGHT).
"But...I swear I can see the sun moving across the sky!"
Yes, it really appears that way, doesn’t it? Kinda explains why, for centuries of human existence, we believed that the Earth was in the centre of the solar system and the Sun moved around us. Now we know better; it’s the Sun at the centre, and the Earth and other planets orbit around the Sun. So that means we have to think a bit harder about why there’s Night and Day, and why it seems that it’s the Sun doing the moving.
