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.
Outer core is made up of liquid NiFe, (Nickel and Iron) while that of the inner core is solid.
The Earth's inner core is solid iron and superrotates (spins faster than the rest of the planet) earthward.
Earth's outer core is liquid mix of iron and nickel, which rotates westward.
The inner core is solid while the outer core is in liquid form.
The inner core is a solid, and the outer core is a liquid.
Because the outer co 're is a liquid rock between the core and the mantle
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
The inner core is a dense ball of solid metal the outer core is a layer of molten matel that surronds the inner core.
The inner core is more dense than the outer core.
Is mercury a inner cor eor outer core
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.
outer core is liquid whereas the inner core is solid
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
The inner core is a dense ball of solid metal the outer core is a layer of molten matel that surronds the inner 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.
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.
inner core and outer core
The inner core and the liquid outer core does.
The inner core is a solid, and the outer core is a liquid.
outer core is liquid whereas the inner core is solid
Crust, mantle, outer core, inner core
The inner core is more dense than the outer core.
Both really the inner core is more hotter than the outer core
