Another way is for surface hoar to develop, or large ice crystal on the snow. This is usually caused by condensation on the snow surface.

practical utility. For example, the application of the BSC to a number of
groups is problematic because of interspecific hybridisation between
clearly delimited species.(Skelton).
It cant be applied to species that reproduce asexually ( e.g Bdelloid
rotifers,eugelenoid flagellates ).Asexual forms of n .....

evaporation of the waste solution mixed with the additives necesary for
the production of borosilicate glass, calcination and elaboration of the
glass. These operations are carried out in a metallic pot that is heated
in an induction urnace. The vitrification of one load of wastes
comprises of the following stages. The first step is 'Feeding'. In this
step the vitrification receives a constant flow of mixture of wastes and
of additives until it is 80% full of calcine. The feeding rate and heating
power are adjusted so that an aqueous phase of several litres is
permanently maintained at th .....
