another, but the energy type stays the same). Heat can transfer (or move) in 3 ways: conduction, convection, and radiation. As you read about the three types of heat transfer, pay attention to: What the heat is moving through (solids, liquids and gases, or empty space) How the heat is being transferred (touch, currents, or waves) Conduction

Apr 04, 2022 Mantle convection is the process by which heat from the Earth’s core is transferred upwards to the surface. It is thought that heating of the mantle by the core creates convection cells in which hot mantle material rises, cooling as it goes, toward the crust until it reaches less dense material, at which point it spreads out then descends.

Heat convection is another means of energy transfer due to the mixing (diffusion) in fluids. On the microscopic scale, there is a relation between the kinetic energy of the molecules of fluid and their thermal energy. If there are heat flux and an increase in the temperature, the increased thermal energy will result in the movement and vibration of the molecules.

In flocabulary The liquid mantle is constantly churning in movements called convection currents. Convection is a method of heat transfer in which hot liquid rises and cooler liquid sinks in a continuous cycle. The large pieces of Earth’s crust are always moving above the mantle. People cannot feel these movements because they are very slow.

The term convection is often used to describe heat transfer that occurs between an object and a fluid flowing across it. Convection is, in essence, a type of conduction. In convection heat is transported mostly by the movement of material, rather than by conduction. Convection in the Earth's mantle is the transport of heat by motion of the mantle.
