WebOct 29, 2024 · The first, known as thermal conduction, occurs when two objects of different temperatures come into contact with each other. When this happens, thermal energy will flow from the warmer object... WebJul 21, 2024 · This heat flow critically depends on the thermal conductivity of liquid iron under the extreme pressure and temperature conditions in the Earth's core. For a long time there has been agreement that convection in the liquid outer core provides most of the energy for the geodynamo and has been doing so for at least 3.4 billion years [2, 5]. chumleigh gardens southwark
