In nature, water-based precipitation will likely always have some liquid and solid/frozen components (especially in higher atmospheric layers) - sleet is generally composed of these phases in comparable proportions. Note that formation processes differ between sleet and other frozen precipitation. For example, hail, being larger in size than sleet or ice pellets, is formed by the accumulation of layers of freezing water in the clouds. Sleet, however, is formed due to temperature difference in the atmosphere sleet sleet fall
