Which statement describes how hail is formed? Ice crystals collect on the rain drops, forming large chunks of ice. Liquid water freezes on solid precipitation in layers, creating large chunks of ice. Water vapor condenses on solid precipitation that is blown by gusts of wind. Water vapor freezes into ice crystals that fall through different layers of air.
