Question

which of the following is not involved in the production of earths magnetic field? view available hint(s) a differentiated structure a composition high in conducting metals oceans rotation of the core

Explanation:

Earth's magnetic field is generated by the dynamo effect in the outer core. A differentiated structure (core - mantle - crust separation) is necessary. The core has high - conducting metals (like iron and nickel). The rotation of the core (along with convection currents) is crucial for the dynamo. Oceans, however, do not play a role in generating the Earth's magnetic field.

Answer:

oceans
