The inner core is very dense. It is the densest part of the planet.
The inner core is the least dense out of the inner core, outer core, mantle, and crust. It is composed mostly of iron and nickel, making it very dense despite being solid.
The inner core is more dense than the outer core. The inner core is mainly composed of solid iron and nickel, while the outer core is liquid iron and nickel. The increased pressure in the inner core makes it more compact and dense.
the inner core is more dense
The crust is the least dense. The inner core is the most dense. So from the middle outwards the layers get less and less dense
The core is the most dense layer
The inner core.

This question is based on a false assumption that the outer core is solid and the inner core is liquid. This is incorrect. It is in fact the inner core that is solid (and so is the most dense) and the outer core which is liquid.
The outer core is less dense than the inner core, and therefore floats on top of it.
The outer core, inner core, mantle, crust, water, atmosphere. This is the order from densest to least dense.
The inner core.
