it's rotation
The Earth's motion around the Sun is what determines a year. This motion is known as revolution, taking approximately 365.25 days to complete one orbit, which is why we have a leap year every 4 years to account for the extra quarter of a day.
It takes one year for Earth to revolve around the Sun. One day for Earth to rotate on its axis.
the earth spins once on its axis during the time we call a day
Because the earths magnetic poles move around from year to year, and even day to day.
equinox
The year is best defined as Earth's motion relative to the Sun. The day is based on Earth's rotation on its axis, and the month is based on the Moon's orbit around Earth.
the earth.
venus does because it rotates as earth does and it is earths twin baby
Yes. We could write a lot more, but yes is the answer.
The earth has arranged to revolve around the sun once a year and rotate on its axis once a day.
Earth has several motions: rotation around its axis (which causes day and night), revolution around the sun (which creates the changing seasons), and precession, a slow wobble of its axis over a 26,000-year cycle. Earth also experiences nutation, a small irregular motion of its axis caused by the gravitational pull of the Moon and Sun.
We call the Earth's daily motion "rotation", and its period ... about 24 hours ... a "day". We call the Earth's annual motion "revolution", and its period ... about 365 days ... a "year".
