Concentrations of radioactive elements generate excess heat. A lot of the heat in the Earth's interior is related to radioactive isotopes of aluminum, and aluminum is less dense than the inner core, which is iron and nickel.

Is it outer core or inner core?

Both really the inner core is more hotter than the outer core


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


What is hotter inner mantle or outer mantle?

Oh, dude, the inner mantle is definitely hotter than the outer mantle. Like, we're talking about temperatures reaching up to 4000°C in the inner mantle compared to a measly 500-900°C in the outer mantle. So, if you're looking for a hot spot, the inner mantle is where it's at.


Would you expect the mantle to be hotter or cooler than the inner and outer cores?

The mantle is expected to be cooler than the inner core but hotter than the outer core. The inner core is the hottest layer of the Earth, while the outer core is composed of molten iron and nickel. The mantle, located between the crust and core, experiences convection currents due to heat from the core, making it warmer than the outer core but cooler than the inner core.


Examples of the outer core?

The outer core is a layer of the Earth below the mantle and above the inner core. It is primarily composed of liquid iron and nickel. The outer core is responsible for generating the Earth's magnetic field through the movement of this liquid metal.


Is the outer core a liquid and the inner core a solid?

Yes, although the inner core is hotter than the outer core, there is more pressure. This pressure is enough to keep the inner core solid.


How can the inner core be hotter than the outer core but be in solid form while the outer core is in liquid form?

the outer core is not under enough pressure to be solid, but the inner core has so much weight being pressed against is from the mantle, crust, outer core, and gravity that it stays as solid nickel and can not move


Why is the inner the outer core liquid?

The inner core of the Earth is solid due to high pressure preventing melting, while the outer core is liquid because it is under less pressure. The outer core is also hotter, allowing it to remain in a liquid state.


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.


Compare and contrast outer and inner cores?

The inner core is solid.The outer core is liquid.It may seem odd that the hotter, inner core is solid while the outer core is liquid magma, but in the inner core you have the entire pressure of the earth pushing down on you.The outer core is hot, molten iron and nickel under extreme pressure. Convection currents cause movements in the liquid outer core. Scientists hypothesize that these movements cause Earth's magnetic field. The outer core surrounds the inner core, which occupies the center of Earth. The inner core is also iron and nickel and is also extremely hot. But pressure within the inner core is so great that it remains a solid.


Which core is hotter outer core or inner core?

The inner core is hotter. The outer core is composed of liquid iron and nickel along with small amounts of lighter elements, with temperatures ranging from 4,000 degrees C to 6,100 degrees C near the boundary with the inner core. Temperatures of the inner core can reach 5,740 C, and pressures are calculated to be around 3,000,000 units of atmospheric pressure. Despite the high temperature, at these pressures the iron-nickel mixture cannot remain molten.


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.
