Q

How does the earth’s core affect the magnetic field?

A

The earth’s core has a solid inner core and a liquid outer core composed primarily of iron. The iron generates magnetic field

Q

How do convection currents affect the magnetic filed?

A

Heat from the core causes molten material in the outer core to undergo convection. Hotter materials rise while cooler materials sink, creating convection currents

Q

How does the Coriolis effect affect magnetic field?

A

The earth’s rotation induces the Coriolis effect, which causes moving fluids to deviate from a straight path. This creates a twisting motion in the molten material

Q

How does the Dynao action affect the magnetic field?

A

The twisting motion of molten material, paired with electrical conductivity of the core, generates electrical currents in the outer core/ These electric currents generate a magnetic field process called Dynamo action
