Final answer:
Sleet is the type of precipitation that consists of ice pellets that bounce when they hit the ground, forming when raindrops pass through a layer of cold air and freeze before reaching the surface.
Step-by-step explanation:
The type of precipitation that consists of ice pellets, which are essentially re-frozen raindrops, and typically bounce upon contact with the ground is known as sleet. Sleet forms when raindrops fall through a layer of cold air and freeze into ice pellets before they hit the ground.
This is different from snow, which is made up of ice crystals that form in cold clouds and fall to the ground intact, and freezing rain, which freezes upon contact with surfaces after falling as a liquid. A rain bomb is an informal term for a sudden heavy downpour and is not pertinent to this context.
