What causes 1 revolution of the Earth?

Answer 1

24 hours. This represents a human day. The exact time of a rotation is roughly

23 hours and 58 minutes, over the course of four years this adds up to a day,

which is why leap years were created. The Earth is constantly rotating, but say

you are in the United States, one 24-hour day would represent a rotation for

your part of the world.

=================================================

Nuts!

It takes the earth 23hours 56minutes 4seconds (rounded) to spin once on its axis.

That's 3minutes 56seconds shorter than 24 hours, and over the course of 1 year,

that adds up to 1 day.

None of that has anything to do with the earth's revolution around the sun,

and it also has nothing to do with Leap Year.

It takes the earth 365.25636days (rounded) to revolve once around the sun.

There's the extra quarter day ... the part after the 365.

If our calendar had 365 days in it every year, then the earth would lag behind

the calendar by 1/4 day every year, because the earth takes longer than that

to complete a revolution, and the extra quarter-days would pile up. The seasons

would begin about 25 days later in the calendar every Century, and we don't

want that.

We can't add 1/4 day to the calendar every year to let the earth catch up to the

calendar, so we add a whole day every 4 years to let the earth catch up, which

is exactly the same thing.

Other than that, the first answer really nailed the whole topic.

Answer 2

One revolution of the Sun takes approximately 365.25 days (one year).

Answer:

Depending on the center of the revolution:

• 28 days around the common center of gravity between it and the moon
• 365 days around the sun
• 225 million years around the Milky Way galaxy

*The revolution of the Earth around its axis, or spin, is called "rotation."

(see the related question below)

Answer 3

The "revolution" of the Earth is around the Sun and takes about 365.25 days.

The "rotation" (spin) of the Earth around its axis is one day, or 24 hours. The actual rotation time is 23 hours and 56 minutes, but the Earth is moving around the Sun and takes another 4 minutes to complete its turn facing the Sun.

Answer 4

The Sun does rotate, but because it isn't a single solid object, different parts rotate at differing speeds. The equatorial areas of the Sun rotate in about 25 days, while it takes nearly 33 days for the polar regions of the Sun to go around once.

Answer 5

Earth takes 365.24 days to make one complete revolution around the sun. It takes one day (approximately 23 hours, 56 minutes) for the Earth to rotate about its axis once.

Answer 6

23hours 56minutes4seconds (rounded)

Answer 7

Sunrise and sunset result from earth rotation.

Answer 8

This is just less than the 24 hours of the "mean solar day". It takes about

23 hours and 56 minutes.

Answer 9

The earth takes precisely 23 hours, 56 minutes, and 4.2 seconds to make one rotation around itself.

Answer 10

Rotation causes the simple phenomenon of dat and night.

Revolution causes seasons.
