Question

Why is inner core solid and outer core liquid

Answer 1

Explanation:

Ans:

Scientists know that the outer core is liquid and the inner core is solid because: S-waves do not go through the outer core. The strong magnetic field is caused by convection in the liquid outer core. Convection currents in the outer core are due to heat from the even hotter inner core.
