Sedimentary Structures Formed in Sand by Surface Tension on Melting Hailstones

D. M. Rubin, R. E. Hunter

ABSTRACT

Craters form when hailstones impact sand. When a hailstone melts, wet but unsaturated sand within the crater is attracted to the hailstone surface by surface tension. Shrinkage of the melting hailstone then produces one or more rings of sand within the impact crater. Craters with inner rings also can form by raindrop impact and surface-tension attraction of sand to the raindrop before the raindrop sinks into the sand.
