The Earth spins on an axis, around the sun, and at the same time rotating.

The rotation around the sun is called the revolution, and it lasts about a year. A rotation is about a day, and when one part of the Earth is dark (facing away from the sun), the other side is bright (facing towards).

Does the sun rays directly reach the earth during night?

Sure. But they don't fall on the part of earth that's experiencing night.


Why does earth day and night?

Earth experiences day and night due to its rotation on its axis. As Earth rotates, one half of the planet faces the Sun, experiencing daylight, while the other half faces away from the Sun, experiencing darkness or night. This cycle creates the 24-hour day-night cycle we observe.


When earth was formed was it day or night?

It was both. As earth was forming out of the accretion disk orbiting the young sun, the part of earth facing the sun was experiencing day, and the opposite part of the earth was experiencing night. It was no different then than it is now.

Is it possible for a day and night to occur without the sun?

No. Day and night are DEFINED based on the sun. Generally, it is day when the sun is shining on a part of the world, and night in the part it isn't shining- yes, that does mean that while it is day somewhere on earth, it is also night somewhere else. Day and night are determined by the Earth Rotating on it's axis. As one side of the Earth is facing the sun and experiencing daylight the opposite side is facing away from the sun and experiencing night time. The Earth's axial tilt causes extremes at the poles where the sun shines continuously for several months or is blocked by the rest of the Earth causing night time for several months. So the North and South poles can experience a 24hr period with only light or only dark.

Why do you have day and night on earth?

Day and night are a result of the earth's rotation on its axis. As the earth turns, different parts are facing towards or away from the sun. It takes 24 hours to complete a rotation: thus, a day is 24 hours long.


How does the motion of the earth cause day and night?

The Earth rotates on its axis (much like if you took a toothpick and pierced a grape with it, then spun the toothpick around between your index finger and thumb). Whichever side of the Earth is facing the Sun, is the part of the Earth that is experience daytime. The side of the Earth not facing the Sun is the side experiencing nighttime.----


Why do you have a day and night cycle?

The Reason for a cycle of day and night is all based on the rotation of the earth. During the day, the part of the earth where you are located is facing the sun, and during the night, the part of the earth where you are located is facing away from the sun.


Why does the earth have day and night?

Earth is rotating on its axis and day and night occur as a result as the Earth spin. If the Sun is shining on a part of the Earth, they are having day time. If a part of the Earth is facing away from the Sun, there are having night time.


How do we get day and night?

We get day and night because, the Earth spins on it's axis around the sun, when the part of the Earth you live in is facing the sun it is day to you. The Moon orbits the earth, for the moon to orbit the Earth once it takes 28 days, when the Moon is facing the part of the Earth you live on it is night to you. Hope this helped x


Why do you see other stars at night but not the Sun?

Day and night are caused by Earth rotating. At night the part of Earth you are on is facing away from the sun, so Earth itself blocks the sun from view.
