Question

Why is it important for Earth’s magnetic field that the inner core is hotter than the outer core?

Answer 1

The inner core is also believed to be moving at a different rate than the outer core. These swirling convection currents result in the earth's magnetic field which keeps us properly oriented for travel, and shields earth from deadly cosmic rays

Answer 2

Answer:

The inner core provides the heat source for outer core convection.

The inner core’s heat produces the Coriolis effect needed for rotation.

The inner core’s heat allows the outer core to conduct electricity.

The inner core provides the energy for Earth’s orbit around the Sun.
