What is precession relating to earths axis?

Answer 1

The earths rotation on its axis causes days and nights. When the rotates and it is dark, that means that your part of the Earth is facing away from the sun. If it is light out on your part of the Earth that means that your part of the Earth is facing the sun. And here is a fun fact: if your part of the Earth is light outside the part of the Earth on the exact opposite side is dark out!

Answer 2

The Earth's rotation causes the apparent rise and set of the Moon and Sun, and its interaction with the Moon causes tides. The rotation also causes a "bulge" in the Earth's spherical shape, with the equatorial region distended outward. The equatorial diameter of the Earth is about 42.6 kilometers wider than the polar diameter (pole to pole).

Answer 3

To me appears that Moon's so called tidal lock,the Effectcould be the very basic cause for Earth's revolution.

Moon acts like a Regulator to keep Earth Annual /Days proportion and or distance from the Sun, almost constant. Variables could be the Moon's orbital Velocity and orbital Radius as primary Factors.

There is a classical Statement relating to Moon and Earth, saying:Moon revolves(around itself)once per each orbit around Earth,called Tidal Lock

In another words according to classical definition, it would mean that Moon has a revolving Axes like planet Earth.

The statement seems to be incorrect or not sufficient.

Moon earns rotating Hinge on the Plane of Rotation so that planet Moon is not revolving itself but makes planet Earth to revolve( the whole mechanism might be combined with other celestial bodies too!). Imagine if a Potter was supposed to work on his pottery machine with his chair fixed on spinning potter wheel, so chair had to be hinged to that rotating wheel making him able to face his job(Target).

By classical statement or definition I would understand, with a physical connection between Earth and Moon the connecting Device should coil around the Moon due to Moon's revolution which is a fully incorrect Concept.

From the view of an Observer beyond these two Planets, Moon will appear fixed but rotating.The Hinge Forcewill act as Torque on Earth's revolving Axes.

Fixed in it's Direction but variable in it's Location on orbital plane,relative to Target(planet Earth).

To better understand dynamic relation between Moon and Earth,instead of using the Terminologies<tidal lock> I would suggest:

hinged on it's orbital Plane>.

Answer 4

Rotation causes:

-- day
-- night
-- the opportunity for everyone on earth to have both day and night regularly.

Revolution causes:

-- seasons (in conjunction with the non-perpendicularity of the rotational axis with respect to the ecliptic)
-- the familiar pattern of particular times of year during which given stars are visible at a given time of night
-- the opportunity to see all the stars and the entire universe, without the sun's interference, in the course
of a year.

Answer 5

The seasons are caused by earth's revolution because it is on a tilted axis. When the earth revolves around the sun during a specific time of the year, one of the poles is closer to the sun than the other pole, because of the tilt. For example, during May, June, July, and August, it is summer in the northern hemisphere because the north pole is pointed closer to the sun, making it warmer. However, during the same time of year, it is winter in the Southern Hemisphere because the south pole is pointed further away from the sun, making it colder, and vice versa during the winter.

An interesting and essential part of this: because earth is spinning (rotating) on its axis, it is acting like a gigantic gyroscope. This is why the tilt of the axis is always pointing to the same spot in the sky, and why the tilt doesn't somehow follow the sun over the course of the year. Without this gyroscopic action, the seasons would be unpredictable.

Answer 6

The revolution of the Earth does not cause changes in the seasons. The TILT of the Earth does. When an area tilts away from the sun, light strikes the earth at a shallow angle, delivering less heat and light. As it tilts towards the sun, light is striking at a more direct angle, delivering more heat and light.

Answer 7

Nothing much. About the only interesting point is that the fact that there is a star almost directly over the north pole is entirely coincidental, and that precession will move the Earth's axis away from Polaris in a couple of thousand years. Could it be that mankind's technological achievements, starting with sea navigation using the north star, are tied to this, or is that just a coincidence as well?

Answer 8

Revolution causes a variation in the length of day and night around the world, and it also causes the earth to experience the various seasons over the course of a year.

Answer 9

The Earth's rotation causes the cycles of Day and Night.

Answer 10

The rotation of the Earth causes day and night.
