Furthermore, while some creatures do have air in their ear canals (and some even have sinuses in their head cavity), the tissues lining these cavities are often highly flexible, and can readily expand, thus forcing out any air and preventing the pressure differential. This essentially implies that there is a certain equalization of pressures involved in this case,which is why there is no pressure difference and why we don’t feel ‘burdened down by air’. Why Are There Stones Alongside Railway Tracks? When we are standing on the surface of the earth, the air pressure around us is equal to 1 atm (atmosphere).
