Entry-level medical education programs are tertiary-level courses undertaken at a medical school. Depending on jurisdiction and university, these may be either undergraduate-entry (most of Europe, India, China), or graduate-entry programs (mainly Australia, Canada, United States).
1 hail: precipitation in the form of balls or irregular lumps of ice (5 mm or more in diameter âanything smaller is considered an âice pelletâ). 2  snow: precipitation composed of white or translucent ice crystals, chiefly in the form of snowflakes.  sleet: a mixture of rain and snow.
It has a greater density and macro-structure. Sleet, snow and hail are all forms of solid water precipitation. The differences are in how they are formed in the atmosphere. Snow is a delicate crystalline structure formed by the nucleation of water into small individual units of frozen water. These fall relatively gently to the ground due to their individual low unit density and mass. Sleet is directly frozen rain, and is essentially the same mass as a raindrop per unit.
