the way in which the earths core spins is believed to be the source of its
Spin science features come from discovery magazine.
When you washing machine is in the spin cycle the agitator should rotate along with the drum of your washing machine and that's normal. There is no way it could be going up and down and will only appear that is is agitating while on spin.
An axle , the drive-shaft ,
Spin it on its axis
roll, glide, spin
The inner core deep inside the earth. It is the layer below the outer core and that is where it spins...
There is no "purpose"; the density of the materials in the outer core are less pressured and spin slower than the inner core. NOTE: the inner core spins faster than the outer, creating Earth's magnetic field.
magnetic field.
they give it a slight wobble
The Earth's magnetic field is generated by the the Earth's spin and the fact that it has molten iron in its core. When convecting molten metals spin they generate electric currents and with these a magnetic field.
The arrows in the figure likely represent the direction and speed of flow within the Earth's inner and outer core. If the arrows in the inner core are longer or more densely packed compared to those in the outer core, it indicates a faster rotation. Additionally, if the arrows in the inner core point in the same direction as the Earth's rotation, while those in the outer core are slower or more chaotic, this further illustrates the difference in spin rates between the two layers.
Earth's molten outer core rotates. That outer core is made up mostly of molten iron. The movement of the molten iron produces the magnetic field.When currents in the outer core force the solid inner core to spin at a slightly faster rate than the rest of the planet causes the Earth to have a magnetic field.
There is actually some evidence that earth's inner core rotates slightly faster, but not by much, only about, or about 0.00075% faster. So it rotates about one extra degree per year. This "hyperrotation" may play a role in magnetic reversals.
rotationis one complete spin on earths axis!!!
Only hard boiled eggs spin because the inner part is solid.
Because they have different viscosities and densities.
Yes, the Earth's core spins within the planet.
