In splash erosion, the impact of a falling raindrop creates a small crater in the soil, ejecting soil particles. The distance these soil particles travel can be as much as 0.6 m (two feet) vertically and 1.5 m (five feet) horizontally on level ground.
Io is composed primarily of rocky material with very little iron. Io is located within an intense radiation belt of electrons and ions trapped in Jupiter's magnetic field. As the magnetosphere rotates with Jupiter, it sweeps past Io and strips away about 1,000 kilograms (1 ton) of material per second.o is composed primarily of rocky material with very little iron.

Scoria Scoria is the vesicular ejecta of basaltic and andesitic magmas. Generally a dark brownish black or red, scoria is generally thought of as the mafic version of pumice, forming when magma rich in dissolved gases is vented.Scoria is composed of volcanic glass fragments, and has few mineral crystals.Its specific gravity ranges from 0.8 to 2.1, making it a relatively light form of rock-sometimes light enough to float (at less than 1.0 specific gravity).coria is composed of volcanic glass fragments, and has few mineral crystals.
