The inner and outer core are different because of the difference in vertical stress within the Earth. As the confining pressure increases it drives up the melting temperature of materials (in this case iron and nickel). The boundary between the outer and inner core marks the point where the confining pressure is so high that it drives the melting temperature of the core material above the temperature within the core. As such it is no longer hot enough to melt the iron / nickel mixture and it solidifies.

Earth's outer core is liquid mix of iron and nickel, which rotates westward.

How is the inner core and outer core different from each other?
The outer core is liquid, the inner core is solid The outer core surrounds the inner core The outer core is iron-rich, the inner core is iron-rich and nickel-rich There is more pressure acting on the inner core The inner core is hotter
How is the outer core different from the inner core?
The inner core is a dense ball of solid metal the outer core is a layer of molten matel that surronds the inner core.
What is more dense inner-core or outer-core?
The inner core is more dense than the outer core.
What is mercury's inner and outer core?
Is mercury a inner cor eor outer core
Which layer of the earth is made up of solid nickel and iron?
The inner core is an alloy of iron and nickel, and the outer core is mainly liquid iron and nickel.The liquid layer made up of hot liquid iron and nickel that surrounds the inner core.
How does outer core different from inner core?
outer core is liquid whereas the inner core is solid
How is the inner core and outer core different from each other?
The outer core is liquid, the inner core is solid The outer core surrounds the inner core The outer core is iron-rich, the inner core is iron-rich and nickel-rich There is more pressure acting on the inner core The inner core is hotter
How is the outer core different from the inner core?
The inner core is a dense ball of solid metal the outer core is a layer of molten matel that surronds the inner core.
What are the 2 different layers of the core?
The inner core and the outer core. The outer core is made of molten metal and the inner core is made of solid metal.
Are the inner and outer core of earth the same?
No. The inner and outer core are both composed primarily of iron and nickel, but the outer core is liquid and surrounds the inner core. The inner core is the innermost layer of Earth and is kept solid by the enormous pressure.
What is the inner and outer earth parts?
inner core and outer core
What creates the shapes of different volcanoes?
The inner core and the liquid outer core does.
What is the differences between the inner core and the outer core?
The inner core is a solid, and the outer core is a liquid.
How does the outer core differ from inner core?
outer core is liquid whereas the inner core is solid
What is the order of the earth's inner layers?
Crust, mantle, outer core, inner core
What is more dense inner-core or outer-core?
The inner core is more dense than the outer core.
Is it outer core or inner core?
Both really the inner core is more hotter than the outer core
