What is the central idea of the theory of the origin of the tilt in Earth's rotation axis?

WHY is the Earth's axis tilted at 23.5 degrees to the ecliptic? We don't know for sure. All rotational motion is "conserved" when masses converge; for example, the rotation of everything in the solar system (with only a couple of exceptions" is counterclockwise as seen from a point far above the North Pole. All the planets orbit that way, the Sun rotates that way, and all but two of the planets rotate that way. We suspect (but ar not CERTAIN) that this is because this is the direction that the primordial planetary nebula was spinning before it collapsed to form our Sun and the planets.
But collisions can change things, and early in its history, w believe that the Earth was involved in a MASSIVE collision - when a planet possibly as big as Mars collided with the Earth. We believe that the mass ejected from the collision formed the Moon. But it also would have changed the rotational pattern of the infant Earth, and is probably responsible for the spin, and tilted axis, of the planet we live on today.
We're not certain; it was more than 4 billion years ago.

Does the cell theory answer the question of how or where life originally came from explain?
No. Cell theory is the theory that cells make up organisms. The only theory dealing with the origin of life is life origin theory.
Who credited with the theory of task rotation?
Karl Marx
The big bang theory and origin of the Earth?
The big bang theory deals with the formation and evolution of the Universe, it has nothing to do with the origin of life on Earth.
Which the theory views the earths surface as composed of slowly moving plates?
Plate tectonics.
The theory describes large scale movements of earths lithosphere is called what?
Plate tectonics
Why is the moons rotation period longer then Earths?
An asteroid/meteor impact is one theory. The truth is that nobody knows for sure, just like the exact origin of the moon is not known for certain.
What theory best describes the moon origin?
Presently, the ejected ring theory best describes the origin of moon.
Plates of the lithosphere float on Core?
Plates of the lithosphere do not float on the core. They float on the asthenosphere (plastic mantle). Due to convection currents and the earths rotation, plates glide over the asthenosphere. This theory is the theory of Plate Tectonics.
The dynamo theory states that earths magnetic field is created in layers?
In the Dynamo Theory, the magnetic field of the earth is created in the outer core. The fluid contained in the outer core creates and maintains the magnetic field during rotation.
Is the big bang theory a theory about the origin of the solar system?
Not exactly, it is a theory about the origin of the Universe; which does include the Solar system...
What theory explains changes in the earths crust?
Contenintal Drift theory
What is the current theory for the origin of earths moons?
the giant impact hypothesis is currently the accepted theory. It basically says that a large asteroid collided with the earth, knocking debris from the earth into space. this debris then formed together over time to form the moon.
Does the cell theory answer the question of how or where life originally came from explain?
No. Cell theory is the theory that cells make up organisms. The only theory dealing with the origin of life is life origin theory.
What theory explains the movement of the pieces of earths surface?
theory of plate tectonics
What was the theory about the earths shape before?
oblong
