My rough guess is that "faster (inner) core is relic of tidal deceleration." Since tidal deceleration of the Earth is due to frictional force exerted by ocean tide on the ocean bottom surface, core can decouple in the tidal braking.

What is the purpose of the earths outer core?
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.
What effects does p and s waves have on earths crust?
They show that the outer core of the Earth is liquid while the inner core is solid.
Is earth one of the inner or outer planet from the sun?
inner
How does earths solid inner core affect seismic waves?
They go faster through the inner core than the liquid outer core.
What is the order of the earth's inner layers?
Crust, mantle, outer core, inner core
What is the purpose of the earths outer core?
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.
Is Earth's inner core surrounded by a liquid outer core?
Yes earths inner core is a dense ball of metal earths outer core is a layer of molten (melted) metal
How does earths inner core affect seismic waves?
They go faster through the inner core than the liquid outer core
Why do scientists believe that the inner core is the source of earth's magnetic field?
Waves traveling through the inner core go faster than those through the outer core.
What is hotter inner mantle or outer mantle?
the earths core is the hottest part of the earth. the metals in the earths outer core is liquid because of the heat and the metals in the earths core is solid but still the earths core is the hottest
Layer of liquid iron and nickel that surrounds earths inner core?
The inner core is the hottest layer of the Earth.
What is the layer just above the earths center?
the center of the earth is called the inner core then you have the outer core and then you have the mantle and lastly the earths crust
What is the most abundant metal In earths core?
Iron is the most abundant metal in the inner and outer core of the Earth.
Earths outer core?
The outer core of the Earth is a liquid layer about 2,260 kilometers thick composed of iron and nickel which lies above the Earth's solid inner core and below its mantle.
What layer is just above the earth's center?
the center of the earth is called the inner core then you have the outer core and then you have the mantle and lastly the earths crust
Is the earth an inner or an outer?
inner
What is Difference between earths inner core and outer core?
The inner core Is solid and the outer core in liquid
