Which of these statements best explains why the inner core of earth does not melt although it has very high temperatures?
the liquid outer core cools the inner core.
the plastic mantle conducts the heat away from the core.
the iron which makes up the core melts at very high temperature.
the different layers of earth exert pressure to keep the inner core solid.

don answer unless your fairly sure of yourself. you

The core is in a cube structure, extreme temperatures make the atoms to move so quickly that there is no alteration of the structure hence, no melting.

Explanation:

In the case of extremely high temperatures, atoms change position but still keep their original shape.

Further explanation:

In the case of high temperatures, the atoms making up a cube move rapidly and change position, the change of position is the melting.

the principles and empirical processes of discovery and demonstration considered characteristic of or necessary for scientific investigation, generally involving the observation of phenomena, the formulation of a hypothesis concerning the phenomena, experimentation to test the hypothesis, and development of a conclusion that confirms, rejects, or modifies the hypothesis.
