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.
Sleet occurs during a winter storm and is caused by rain falling into a cold layer of air aloft which has to be below freezing. As the raindrops fall through the cold layer of air, they freeze and become small ice pellets. When they hit your car windshield or your windows at home, they can make quite a racket.
