the way in which the earths core spins is believed to be the source of its
it spins almost at the same rate as earth (one revolution every 24hrs). To be very exact, it actually needs about 1 millisecond less than the rest of earth, but i doubt you need to know that.
The inner core deep inside the earth.
It is the layer below the outer core and that is where it spins...
there are 2 cores in the earth, the outer core and the inner core.
Surrounding the inner core of the Earth is the outer core. Surrounding that is the mantle. And floating on top of that is the crust.

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

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.
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.
Only hard boiled eggs spin because the inner part is solid.
rotationis one complete spin on earths axis!!!
Because they have different viscosities and densities.
Yes. When we're talking about the Earth, 'spin' and 'rotate' are the same thing.
because of the way rock and debris hit them they spin faster
