What is the scientific definition of day?
It is the 24 hour period, for planet Earth. An hour is 60 minutes and 1 minute equals 60 seconds. 24 hours is called the "solar day". It depends on the Sun's position in the sky. There are other definitions of "day" The "sidereal day" is equal to the Earth's rotation period. That's about 4 minutes less than the solar day. That's because the solar day depends on the Earth's motion around the Sun as well as Earth's rotation. Other planets have their own day lengths.
Earth inner core definition?
solid center of earth
Who was the first man to discover that the earth was a magnet?
No one really knows who discovered Earth. But One day, we will find out who discovered Earth and we'll finally have answer.
Why can the whole Earth not experience day at one time?
Because the sun can only shine on one half of the Earth at a time.
What is the definition of the earth's mantel?
The earth's mantle is the coating around the inner core.
How many days on Mercury is equal to one day on Earth?
Mercury rotates once in about 59 Earth days. That is often called its "day". There's another definition of day called the "solar day". For Mercury that's 176 Earth days. So, you can see there's only a small fraction of a Mercury day in one Earth day.
What is the length of venues day?
I think you mean "Venus". That planet rotates in about 243 Earth days. That is one definition of a "day". It is called the "sidereal day". There is another definition called the "solar day", which takes into account the planet's motion around the Sun. For Venus this is about 117 Earth days long.
What planet is only one AU from the sun?
By definition, it's the Earth.
How long does one day last in earth?
Solar day . . . 24 hours (definition) Sidereal day . . . 23hours 56minutes 4seconds (units defined by the solar day)
How many earth days is one day on this planet?
This is planet Earth, so one Earth day is one day on this planet.
What planet rotates on its axis in one day?
The Earth rotates on its axis in one day. Strictly speaking that's the "sidereal day" not the "solar day". Also, by definition, each planet rotates once in a period that's the "sidereal day" for that particular planet.
Waning moon definition?
A moon that is reducing in the size, of the illuminated surface visible to earth, day by day.
What is the name of the planet with the longest day compared to an earth day?
Venus. The length of "day" is 243 Earth days. That's the rotation period which is called a "sidereal day". However, there's also a "day" called the "solar day". That's the time for the Sun to complete one apparent journey around the sky. For that definition of "day", it is Mercury that has the longest day at about 176 Earth days.
What is the definition of rotation grade 4?
The earth spins or rotate from west to east on its axis it takes 24 hours or one day at the same time the earth is moving around the sun.
What is the period of revolution for the earth in earth years?
Earth's rotation takes exactly one Earth year (definition).
What is mercury's length of day?
Mercury rotates once in about 58.6 Earth days. That's one definition of its day. However, Mercury's "solar day" lasts about 176 Earth days. That "day" is based on the position of the Sun in the sky. It depends on Mercury's orbital motion as well as its rotation on its axis.
How many earth years does it take earth to revolve around the sun?
By definition, one.
