24 hours, or a rotation of the Earth, depending on how you look at it.
Edit:
The Earth actually takes only about 23 hours and 56 minutes to rotate once.
But the Earth is also orbiting the Sun. The extra 4 minutes are needed to allow
for the effect of the Earth's orbiting on the apparent position of the Sun in the sky.
In fact 24 hours is called a "solar day", whilst the rotation time is a "sidereal day".
What else can I help you with?
What defines one year on earth?
a year
How long does it take the earth to go round once?
It takes approximately 24 hours for the Earth to complete one full rotation on its axis, which defines a day.
How are the length of the day and year related to Earth's movement through space?
WELL THE LENGTH OF THE DAY IS RELATED TO THE Rotation AND REVOLUTION OF THE PLANET BECAUSE THE PLANET HAS LENGTH BUT IT MIGHT NOT HAVE THE SAME THING AS OUR LENGTH AND IT HAS THE SAME ROTATION AND REVOLUTION.WHAT DO YOU YOUNG GUYS AND LADIES THINK ABOUT MY ANSWER ?PLEASE COMMENT ON IT I WILL APPROACHED THAT BY.
How long does it take the earth to make one spin?
for a rotation is takes like 365 days or like 365 1/4 days
How many hours does it take the earth to spin 1 time?
23hours 56minutes 4seconds (seconds are rounded)
How long does it take for earth to orbit its own axis for one day?
The Earth takes approximately 24 hours to complete one full rotation on its axis, which defines the length of a day. However, a more precise measurement of this rotation, known as a solar day, is about 24 hours due to the Earth’s simultaneous orbit around the Sun. This rotation is responsible for the cycle of day and night experienced on the planet.
How many earth days is one day on this planet?
This is planet Earth, so one Earth day is one day on this planet.
Is it true or false that one revolution of the earth make up the hydrosphere?
False. All of the water on Earth makes up the hydrosphere. One revolution of Earth around the sun defines a year.
What movement by the earth determines the length of one day?
One rotation by the Earth round its axis to bring the 'mean Sun' back to the meridian defines one day.The mean Sun is a Sun which comes to the meridian regularly once a day. In practice the real Sun can be fast or slow by up to 10 minutes, so the mean Sun is a fictitious sun for which those daily variations are averaged out over a year.
What controls the length of a earth day?
The length of an Earth day is primarily controlled by the planet's rotation on its axis. It takes approximately 24 hours for Earth to complete one full rotation, which defines the day-night cycle. Factors such as gravitational interactions with the Moon and the Sun, as well as geological activities like earthquakes and glacial movements, can slightly alter the rotation speed and, consequently, the length of a day over time.
What defines night and day?
Night and day are defined by the rotation of the Earth on its axis. During the day, the side of the Earth facing the Sun experiences daylight, while the opposite side experiences night. This cycle takes approximately 24 hours to complete.
Is one day on earth twenty seven hours?
No. One day on Earth is 24 hours.
