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.
What else can I help you with?
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 outer core is liquid and composed of molten iron and nickel, while the inner core is solid due to the extreme pressure at its center. The outer core's movement creates Earth's magnetic field, while the inner core's solidification is thought to be a result of cooling over time.
Which one comes first the inner core or the outer core?
The outer core comes before the inner core. The Earth's structure consists of the inner core, outer core, mantle, and crust. The outer core is a layer of molten iron and nickel that surrounds the solid inner core.
What is more dense inner-core or outer-core?
The inner core is more dense than the outer core. The inner core is mainly composed of solid iron and nickel, while the outer core is liquid iron and nickel. The increased pressure in the inner core makes it more compact and dense.
What are the two parts of the core?
the two parts of the core are the inner core and the outer core
How does outer core different from inner core?
outer core is liquid whereas the inner core is solid
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.
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
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 creates the shapes of different volcanoes?
The inner core and the liquid outer core does.
What is thicker inner or outer core?
The outer core is thicker than the inner core. The outer core is about 2,260 kilometers thick, while the inner core is approximately 1,220 kilometers thick.
How does the outer core differ from inner core?
outer core is liquid whereas the inner core is solid
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 is the outer core different from the inner core?
The outer core is liquid and composed of molten iron and nickel, while the inner core is solid due to the extreme pressure at its center. The outer core's movement creates Earth's magnetic field, while the inner core's solidification is thought to be a result of cooling over time.
What is the order of the earth's inner layers?
Crust, mantle, outer core, inner core
Is it outer core or inner core?
Both really the inner core is more hotter than the outer core
What difference between inner core and outer core of earth?
The inner core Is solid and the outer core in liquid
