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