liquid
There are differences in chemistry (the mantle is mainly ultramafic rock--the outer core is metallic), in phase (the mantle is predominately solid--the outer core is liquid), in depth (the outer core is closer to the center of the Earth), and in density (the outer core is more dense).
The outer core of the Earth exists in the liquid phase of matter. It is predominantly composed of molten iron and nickel, which results in the liquid state due to the high temperatures and pressures present in the Earth's interior.
The primary piece of evidence used to determine the phase of the Earth's core is seismic waves. By studying how seismic waves pass through the core, scientists can infer information about its composition, temperature, and state (solid inner core, liquid 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.
Yes, Inter core has more pressure than outer core and that's why outer core is solid, because there is not enough pressure in outer core.
the outer core is located next to the innner core
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.

outer core is liquid whereas the inner core is solid
outer core is liquid whereas the inner core is solid
The inner core is a solid, and the outer core is a liquid.
