Van Allen Radiation Belt
Particles move from areas where there are more of them to areas where there are fewer of them through a process called diffusion. This movement occurs in an attempt to achieve equilibrium in concentration levels.
Such areas are called Van Allen belts.
Passive transport that moves particles away from areas is called facilitated diffusion. This process uses transport proteins to help molecules or ions pass through the cell membrane, moving from areas of higher concentration to areas of lower concentration without using energy.
Particles moving from problem areas to less crowded areas are called diffusion. Diffusion is the process by which particles spread out and move from areas of high concentration to areas of low concentration to create equilibrium. This movement occurs due to the natural random motion of particles.
The random movement of particles which happens all the time ensures that they move into any space between other particles. This is called diffusion.
The bunched up areas of particles in a longitudinal wave are called compressions. These regions have high density of particles due to the waves' alternating compressions and rarefactions as they pass through a medium.
The subatomic particles that move in response to a potential difference are called electrons. These negatively charged particles flow from areas of high potential to low potential in a process known as electric current.
Active transport usually involves the movement of particles from high to low concentration.
Diffusion
This is called diffusion, but it is a purely statistical process - randomly moving particles have a higher probability of spreading from an area of high concentration to an area of low concentration than the other way around, simply because there are more of them in the area of high concentration.
This movement of particles is called diffusion, where particles tend to move from regions of higher concentration to regions of lower concentration until equilibrium is reached.
