When there is continuous movement but no change
The skin is the body's best natural barrier against germs. It acts as a physical barrier to prevent germs from entering the body and also has its own defense mechanisms, such as producing antimicrobial substances. Proper hygiene practices also help to maintain the skin's barrier function.
Agar jelly has good moisture retention properties, making it an effective barrier against dehydration. However, it is not an effective barrier against oxygen transmission and can allow gases to pass through. Agar jelly can also absorb water and become softer over time, which may affect its barrier properties.
we have the ozone layer that that acts as a barrier of the earth, ozone layer protects us from harmful effect of ultraviolet light...and the other barrier is what we call the earths magnetic field of magnetosphere which protect us from the sun's solar burst....
Sedimentation is the process where particles in suspension can settle out of the fluid where they have been transported, and begin to rest on a barrier.
Sedimentation was discovered by Reuss in 1809. Sedimentation is the suspension of particles that settle out of the fluid in which they are entrained and come to rest against a barrier.
In chemical engineering terms, sedimentation refers to the tendency for the particles in suspension to settle out of the fluid in which they are entrained, and come to rest against a barrier. This is due to their motion through the fluid in response to the forces acting on them: these forces can be due to gravity, centrifugal acceleration or electromagnetism.

Material that settles to the bottom of a liquid; lees. For the definition of sedimentary rock, use the link below to the related question.
Diffraction is the name given to the tendency for waves to spread out when they meet a gap in a barrier. This phenomenon occurs when waves encounter an obstacle or pass through an aperture, causing them to bend and spread out.
The blood-brain barrier is effective against the passage of ? Metabolic waste such as urea
Putting dunes on beaches is a natural barrier against coastal erosion.Having a thick treeline of sturdy trees can serve as a natural barrier against some tsunamis.
A gas cannot easily pass through a liquid or a solid however it can be entrapped in it . If a gas bubble is formed in a liquid it moves upward and escapes out of the liquid. Gas cannot pass through a solid barrier.
In quantum mechanics, an infinite potential barrier is a theoretical concept that represents a boundary that particles cannot pass through. This barrier has the property of reflecting particles back, rather than allowing them to pass through. The effects of an infinite potential barrier include the confinement of particles within a certain region, leading to phenomena such as particle wave interference and the quantization of energy levels.
A barrier against diseases, injury, and infection
True. The skin acts as a barrier against germs and also controls body temperature.
