as i dont know
I love this question. It happens at two places. It happens at the International Dateline, in a sense. At the dateline, it is ALWAYS one day on one side, and another day on the other side. It also happens at "midnight", as midnight moves across the planet's surface each day.
Alas this planet only has the one sun, so if the sun is on one side of the planet then the other side would be in darkness.
If a planet is not turning on its axis, then essentially there is no day and night. One side of the planet would be day, the other, night. I personally think the day side of the planet would roast and the night side would freeze, but that's just me.Note: In fact, the planet would have long days and nights because of its orbit around the Sun.
yes, but the earth rotates so that a new piece of the earth faces the sun day in and day out. this is what causes day and night on the planet. (Shine a flashlight on an orange, and turn the orange in your hand.)
Mercury because one side of it is always turned towards the Sun.
If the earth does not rotate, we will not have night and day. One side of the world will always be dark, and one side will always be light.
Sunlight is always shining on one half of the Earth as the planet rotates on its axis, causing day and night. This rotation creates a cycle of 24 hours with half of the globe facing the sun ("day side") and the other half facing away from it ("night side").
This is planet Earth, so one Earth day is one day on this planet.
During its rotation around its own axis half of the planet faces the sun [day] and half faces away from the sun [night] As the planet continues to turn so night slowly turns into day and then day into night and so on.
Earth makes one complete rotation in 0.99726968 days... that is 23 hours 56 minutes 4.100352 seconds. The rotation of a planet is when it spins on its axis. Different planets have different rotational periods. A rotational period is the amount of time it take an object to make one revolution. A rotational period can be more or less than the planet's actual day length depending on the direction it orbits its star relative to the direction it rotates. The rotational period and the day length are only the same when either the planet does not rotate(1 day = 1 year) or when the planet rotates at the same speed it orbits(one side always has day).
One side of the Earth is always in darkness because the Earth rotates on its axis, which takes about 24 hours to complete a full rotation. As the Earth spins, one hemisphere faces the Sun and experiences daylight, while the opposite hemisphere is turned away from the Sun and is in darkness. This continuous rotation creates the cycle of day and night across the planet.
