Does the outer core spin?
When Earth's core spins, the planet turns on its axis and completes its rotation. One complete rotation is one day and night.
Why does Earths inner core solid?
The Earth's rotation on its axis
How was the rotation rate of Jupiter's core determined?
by radio observations of Jupiter's rapidly spinning magnetosphere
Why does Earth have a magnetic field and Venus does not?
Lack of convection in the core of VenusExtremely slow rotation rate
What is relation between sun differential rotation and core rotation of earth?
The weird thing about the Sun's rotation - as compared to Earth's rotation - is precisely that it is a differential rotation. That means that at the equator, the Sun rotates faster than near the poles. There is some recent evidence that the inner and outer cores of Earth do indeed spin at different rates and at different rates compared with the rest of the planet.
Does the outer core spin?
When Earth's core spins, the planet turns on its axis and completes its rotation. One complete rotation is one day and night.
How did gravitational force emerged?
the rotation of the earth with its iron core
What is the major process that is thought to produce the Earth's magnetic field?
The convection in the outer core, along with rotation of Earth that causes rotation of the outer core, initiates a flow of electric current in the core. This flow of current within the core produces and sustains Earth's magnetic field.
Where does much of Earth's internal heat come from?
rotation of the earth's core
Why does Earths inner core solid?
The Earth's rotation on its axis
What does the rotation of the solid inner core produce?
It produces earth's magnetic field.
Why does Earth Have a strong magnetic field?
Because it has a molten metallic core and a fast rotation.
What creates Earth's magnetic field and where does it take place?
The rotation of the molten, iron core of the Earth.
How was the rotation rate of Jupiter's core determined?
by radio observations of Jupiter's rapidly spinning magnetosphere
Why does Earth have a magnetic field and Venus does not?
Lack of convection in the core of VenusExtremely slow rotation rate
What does time-distance graph of seismic waves show?
Comparison of waves going through the solid inner core and those just skimming it can show the rotation of the inner core.
What causes the Earth magnitic field?
The inner core and outer core of the planet are composed primarily of iron and nickel. The outer core is liquid and the inner core is solid. It is thought that the convective motion of the liquid outer core is responsible for generating the main field. Recent studies indicate that the inner core of the Earth may rotate a bit faster than the outer core and it is possible that this rotation may be associated with field reversals.
