Question

2 multiple choice 1 point
which layer(s) of the earth is responsible for earths magnetic field?
inner core and mantle
inner and outer core
crust and mantle
crust

Explanation:

Earth's magnetic field is generated by the geodynamo effect: the liquid outer core (composed of iron-nickel alloys) flows around the solid, iron-rich inner core, creating electric currents that produce the magnetic field. The crust and mantle do not contribute to this field.

Answer:

Inner and Outer Core
