Our 24-hour day is approximately the time that it takes for the Earth to spin around once, from noon to noon. Becuase the Earth's orbit is an ellipse (rather than a circle), the actual duration of a "solar day" isn't the same from day to day; the "noon" position of the Sun in the sky actually describes a figure-eight path called an "analemma".
The actual time that it takes for the Earth to spin 360 degrees - one full turn - is 23 hours 56 minutes, which is the "sidereal day" with respect to the fixed stars.
What else can I help you with?
How do the movement of earth provide a basis for measuring time?
The Earth's rotation on its axis creates day and night, allowing us to measure time in 24-hour increments (1 day). The Earth's orbit around the Sun creates the cycle of seasons, which gives us a basis for measuring longer periods of time (months and years). By observing these movements, humans have developed various methods of measuring and tracking time.
The motion of the earth that gives us night and day is called?
The motion of the Earth that gives us night and day is called rotation. The Earth rotates on its axis, an imaginary line that runs from the North Pole to the South Pole, completing one full rotation approximately every 24 hours. This rotation causes different parts of the Earth to face towards or away from the Sun, creating the cycle of day and night.
Which kind of movement of the earth causes day and night?
The rotation of the Earth on its axis causes day and night. As the Earth spins, different parts of the planet are either facing towards the Sun (day) or away from the Sun (night), creating a cycle of light and darkness.
How do the the rotations and revolution of earth differ?
rotaion is spinning
What does the tilt of the earth do for us?
it gives us the power of time and if there was no rotation of the earth there is no movement and if there is no movement there is nothing living on earth so there would be no us thats why the rotation of the earth is so important!
What causes the apparent movement of objects across the sky during day or night on earth?
The rotation of the earth is what gives motion to the heavens.
Is March twenty-six Earth Day?
No; Earth Day is April 22. However, the last Saturday in March (the 26 in 2011) is the observance of "Earth Hour", when businesses and individuals commit to not using electricity for one hour to demonstrate their support for the Earth, the environmental movement, and Worldwide Fund for Nature.
Which movement represents a day when the earth moves around the sun?
The Earth's spin, or rotation on its axis gives us a day.

What two planets have similar length of day?

How many miles does the earth travel in a day?
The Earth travels approximately 1.6 million miles in a day as it orbits the Sun at an average speed of 67,000 miles per hour. This movement is part of the Earth's revolution around the Sun, which takes about 365.25 days to complete.
