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.

What is the difference between the inner cores and outer cores?
The inner core is a solid, and the outer core is a liquid.
Compare and contrast the outer planets of the solar system with the inner planets?
Outer: big, cold, gas giants (and lots of satellites) Inner: small, rocky, warn (to hot).
How many planets have inner and outer cores?
All terrestrial planets, such as Earth, Mercury, Venus, and Mars, have inner and outer cores. These cores are composed of mostly iron and nickel, with the inner core being solid and the outer core in a liquid state. Gas giant planets like Jupiter and Saturn also have cores, but they lack a distinct separation into inner and outer regions like terrestrial planets.
The inner and outer cores are probably composed mostly of?
Iron '
How are the inner and outer cores the same?
they are both part of the earth
Which of Earth's cores is liquid?
The outer core is liquid; the inner core is solid.
Does the core contain the lower mantle?
No. The outer and inner cores are separate from the mantle.
How does the temperature of the inner planets compare to the temperature of the outer planets?
The inner planets are typically warmer than the outer planets. This is because the inner planets are closer to the sun and receive more direct sunlight, leading to higher temperatures. In contrast, the outer planets are much farther from the sun and are colder as a result.
How are the compositions of the inner and outer planets different?
A basic, simplified answer is: The inner planets are mainly rock with iron cores. The outer planets are mostly gas, or liquefied gases.
How thick is the earth's core in kilometers?
Combined the inner and outer cores are 3500 km thick.
What is core the layer of earth?
-Subdivided into outer and inner cores -Outer core is made up of nickel-iron alloy -Inner core is made up entirely of iron
How are the compositions of the inner planets and outer planets different?
A basic, simplified answer is: The inner planets are mainly rock with iron cores. The outer planets are mostly gas, or liquefied gases.
