Ridging / formation of pressure ridges
Refers to the process in which pressure ridges are formed.
Refers to the process in which pressure ridges are formed. A pressure ridge is a line or wall of broken-up ice formed by the influence of pressure. This can also be the breakup of an ice floe into several blocks (which doesn’t happen in the case of rafting). The breakup is due to the ice’s growing thickness, which causes bending moment to exceed tensile strength at its surface. In other words, at some point the ice is no longer flexible enough to withstand the pressure without breaking.
