3the number of particles in a substance Densitythe number of particles in a substanceHow tightly packed the particles areDraw exampleMore dense materialWill sinkLess dense materialWill rise or float
4ConvectionAs mantle is heated by outer core the particles (atoms and molecules) move faster and farther apartThis movement makes the hot part of the mantle less denseThe material will slowly rise toward the crust
5ConvectionMantle material is cooled as it nears the crustThis cooling causes the particles in the material to move slower and closer togetherThe cooler material will slowly sink back toward the outer core
7ConvectionConvection is a flow of a fluid or air due to heating and cooling IE: Hot air rises. Cold air falls.
