Relocation diffusion depends on 'blank' moving the idea

Diffusion by relocation is a sequential process in which the ideas are transmitted by their carrier agents (such as immigrants) as they evacuate old areas and relocate to new ones.

Diffusion is the net movement of substances from an area of higher concentration to an area of lower concentration. This movement occurs as a result of the random and constant motion characteristic of all molecules, atoms, or ions (due to kinetic energy) and is independent from the motion of other molecules.

Diffusion stops when the concentration of the substance is equal in both areas. This does not mean that the molecules of substance are not moving any more, just that there is no overall movement in one direction. Molecules of substance are moving equally in both directions.

No - particles continue to move even after they are evenly spread out by the process of diffusion.
