How does heat from Earth's core travel to the surface to warm up the mineral springs we talked about.

• Heat travels through direct contact between the inner core and crust.

• Heat moves directly from the outer core to the crust, bypassing the mantle.

• Heat is trapped inside the inner core and cannot travel to the surface.

• The inner core transfers heat to the mantle, which then radiates it through to the crust.
