Question

a magnetic field protects earth from the suns high-energy particles. what two processes are involved in the formation of earths magnetic field?
the movement of materials in earths mantle and earths rotation
the movement of metals in earths core and earths rotation
the movement of solar wind toward earth and earths revolution
the movement of eruptions from the suns surface and earths revolution

Explanation:

Earth's magnetic field is generated by the geodynamo effect. This relies on the convective movement of molten iron-nickel metals in the outer core, combined with Earth's rotation, which creates and sustains the magnetic field. The other options incorrectly reference mantle movement, solar wind, solar eruptions, or Earth's revolution, which are not involved in generating the magnetic field.

Answer:

the movement of metals in Earth's core and Earth's rotation
