How does the rotation of earth cause night and day?

Answer 1

The earth's rotations cause day and night. The earth makes one complete rotation every 24 hours. At any point in that rotation, an area of the globe is facing the sun. This is day. As the Earth continues to rotate, it will eventually rotate away from the sun making it night. The absence of direct sunlight is what forms night.

Earth's spinning does cause night and day. This is because the spinning changes the Earth's position to the sun's exposure.
The earth spins around on its axis, causing different sides to face the sun at different times. The tilt of the axis towards the sun is what causes the seasons. Two different forces work on the earth to move: gravity and inertia. Inertia causes the earth to continue moving without stopping, like a ball rolling down a hill. Gravity keeps the earth moving around the sun, because without the sun's gravity, inertia would cause the earth to move in a straight line in space forever. Without inertia, the earth would crash into the sun because the sun is pulling the earth closer to it. Together, they cause the earth to move around the sun and around its axis, causing day and night.
If you can get someone to help you for a few minutes, try this:

Go into a dark room with a flashlight and another person.

Shine the flashlight on the person's front. Now his front is light. His face,

the buttons on his shirt, and his belt-buckle are visible. Also, he can see

the flashlight.

Now have the other person stay in the same place, but turn around slowly.

When his back is to the flashlight, then the back of his head, the back of his

shirt, and the seat of his pants are visible. But his face and the buttons on

his shirt are turned away from the flashlight, so they are dark. Also, he can't

see the flashlight, because his eyes are facing the other way.

If you cannot understand the similarity between this little exercise and the

relationship of the sun and the earth, then perhaps it would be better to

simply stop worrying about it, and think about other things.
A sphere such as the earth can only be illuminated from one side, given a single light source such as the sun. As the Earth rotates every 24 hours relaive to the sun, the illuminated part moves around the surface to give the day and night cycle.

When a side of the Earth is facing the sun it is day time. When a side of Earth isn't facing the sun it is night time.
the earth is rotating the sun so say when North America is pointing away from the sun its night and when its pointing to the sun its day
the rotation of the earth influences day and night by the line between day and night.

Answer 3

At least one side have to be looking at the sun. But because the sun does not move the other side has to be night.
