Seismic WavesSeismic WavesA wave of energy that travels through the

Earth and away from an earthquake in all directions

P Waves

A seismic wave that particles of rock to move in a back and forth directions

A seismic wave that causes particles of rock to move in a side to side direction

ConvectionConvection

The movement of matter due to differences in density ; the transfer of energy due to the movement of matter

Convection cells is rotating circular plate filled with a purple liquid of varying shades. Heated from below, the liquid creates a complex pattern of concentric cells which disappear when the plate spins
