Conduction The direct transfer of thermal energy from one substance to another substance that it is touching.
Convection The transfer of thermal energy by the movement of a fluid.
Density The amount of mass of a substance in a given volume; mass per unit volume.
Convection Current The movement of a fluid, caused by differences in temperature that transfers heat from one part of the fluid to another.
What is conduction? Conduction is heat transfer within a material or between materials that are in direct contact.
What is the role of gravity in creating convection currents? Gravity pulls denser (cooler) material toward Earth’s center more strongly than it pulls less dense (hotter) material.
