Sleet is frozen liquid that freezes just before reaching surface. The difference between sleet and snow is that sleet contains more liquid, doesn’t crystallize and freezes only a short distance above ground. You can hear it bouncing when it hits the ground because of the hard shell, even if some of the core remains liquid.

Sleet is a type of precipitation that occurs when precipitation originating within or above the warm layer of a warm front, and falls as a liquid droplet into the cold layer, where it can partially refreeze into an ice pellet.
