The inner core is a solid, and the outer core is a liquid.
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 core Is solid and the outer core in liquid
The inner core Is solid and the outer core in liquid
Iron '
they are both part of the earth
the core is 3470km thick (the inner is 1270km and the outer is 930km thick) from the top of the outer layer of the core to the crust is 2850km (called the mantle) , and the crust itself is 25 miles beneath continents and 6.5 miles thick beneath oceans..
The inner core Is solid and the outer core in liquid
Inner planets are mostly rock and outer planets are mostly gas.
both rotate on their axis
The outer core is liquid; the inner core is solid.
No. The outer and inner cores are separate from the mantle.
A basic, simplified answer is: The inner planets are mainly rock with iron cores. The outer planets are mostly gas, or liquefied gases.
