Question

drag each tile to the correct box.
arrange the events in the correct order to describe how the magnetic field forms around earth.
the electric currents create a magnetic field around earth.
a continuous flow of liquid iron creates electric currents inside earth.
iron - rich magma heats up inside earth.
convection currents form, cycling magma between the core and the crust.

Explanation:

To determine the correct order, we analyze the causal chain of Earth's magnetic field formation:

1. First, the iron - rich magma inside Earth heats up. This heating is the initial trigger for the subsequent processes.
2. As the magma heats up, convection currents form. These currents cycle the magma between the core and the crust.
3. The movement of the magma (specifically the liquid iron within it) leads to a continuous flow of liquid iron. This flow of liquid iron creates electric currents inside Earth.
4. Finally, these electric currents create a magnetic field around Earth.

Answer:

1. Iron - rich magma heats up inside Earth.
2. Convection currents form, cycling magma between the core and the crust.
3. A continuous flow of liquid iron creates electric currents inside Earth.
4. The electric currents create a magnetic field around Earth.
