the stellar mass was at least three times that of the Sun, a black hole
The earth rotates at a rate of about 24 hours per cycle, so every 24 hours every point on the earth's surface between the Arctic Circle and the Antarctic Circle goes from being on the side that is flooded with sunshine, around to the side where the sunshine doesn't reach, and around the other side into the sunshine again, ending up close to the same position with respect to the sun every 24 hours.
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.
A day is 12 hoursA night is 12 hours
Jupiter does have day and night due to the rotation of its axis. Jupiter turns on its axis every 9.84 hours and spins much faster than most of the planets.
Because the earth is a ball, and the sun is the only light source responsible for day and night, the earth can only be illuminated on one side at a time. Luckily, the earth spins so that every side of the earth gets a piece of sunshine. The rotation of the earth is what causes day and night.
Gravity does not cause the day and the night.
Day and night are caused due to Earth's axial rotation around the Sun; along with the fact that we have just one Sun.
You get day and night due to the rotation of the Earth about its own axis. Only on the side facing the Sun is it daytime. On the other side it is night.
due to elliptical shape of earth,the size of days and night are vary
The rotation of the Earth results in its day and night cycles. The exception to this is in the polar regions that have day and night for 6-months each due the Earth's tilt.
The average length of a day on Earth is about 24 hours (23 hours, 56 minutes, and 4 seconds to be precise), while the length of night is the same. This is due to the rotation of the Earth on its axis, which creates a day-night cycle.
Day or 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
This is because during daytime there is exchange of O2 gas due to diffusion whereas at night time there is exchange of CO2 . This is how diffusion differ in day and night time

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.
The day and night is provided us due to the rotation of earth at its own axis. Answer2: The equal day and night is the result of the Equinox, where the declination of the sun rises due east and sets due west. The sun's declination is zero.
At night, the air near the ground is cooler and denser, which refracts sound waves upward away from the ground. This can prevent some of the noise from being heard on the ground, making planes seem quieter at night compared to during the day. Additionally, there tends to be less background noise at night, making plane noises more noticeable during the day.
