What evidence indicates that Earth has a solid inner core and a liquid outer core?

• P-waves and S-waves

• A-waves and B-waves

• through drills

• there is no evidence

How does convection occur within the interior of Earth?

• there are not convection currents in the Earth

• Uneven heating of the Earth is how convection currents occur. The inner core heats the mantle that falls to the crust and then cools rising back down to the core creating a current.
