Is Earths rotation axis fixed in space?
No, Earth's rotation axis is not fixed in space. It undergoes a slow wobble known as precession, which takes about 26,000 years to complete one full cycle. This causes the orientation of Earth's axis to change over long periods of time.
What do you call the slow movement of earths axis with a period of 26000 years?
Procession of the Equinox
How many months after earths perihelion position does earths aphelion position occur?
Earth's aphelion position occurs approximately six months after its perihelion position. Perihelion, when Earth is closest to the Sun, typically occurs around early January, while aphelion, when Earth is farthest from the Sun, usually takes place in early July. This timing is a result of Earth's elliptical orbit around the Sun.
What is earths axis slowly but continuously points in different directions known as?
I think you are referring to a phenomenon called Nutation.
What is earths precession?
The Earth is a spinning top (gyro) with a different moment of inertia about the spin axis than the other two axis. Therefore, it acts like a spinning top with both precession and nutation. Precession of the polar axis (relative to a 'fixed' distant star) forms a cone. The precession period (~26,000years) is the time it takes for the cone to be traced. Nutation occurs normal to the precession cone and has a much faster period (~18.6yrs).
What are earths four motions?
Earth has four main motions: rotation, which causes day and night; revolution, which causes the annual seasons; precession, which causes a slow wobble in its axis; and nutation, which causes a slight variation in the tilt of its axis.
What is the scientific name for the date that the earths is closes to the sun?
perihelion
What is a very slow motion of earths axis that requires 26000 years?
precession

What causes earths winds and weather to change?
I will find the answer lator!

How does stress change earths crust?
It causes it to deform - this deformation is called "strain".
Earths tilt does not stay the same because of its what?
precession
How many months after earths perihelion position does earths aphelion position occur?
Earth's aphelion position occurs approximately six months after its perihelion position. Perihelion, when Earth is closest to the Sun, typically occurs around early January, while aphelion, when Earth is farthest from the Sun, usually takes place in early July. This timing is a result of Earth's elliptical orbit around the Sun.
Which is thought to be most responsible for earths ice ages?
Earth's precession
What is the distance from earth to the sun when it is nearest from the sun?
The Earths orbital distance from the sun is 147,098,290km (91,402,641 miles) at its closest (Perihelion).
