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.

What Io is Made of. An idea of the interior composition can be guessed from the density of Io, which is about 3.5. The density of iron is about 5, and that of silicate rock is 3, so the inside of Io must be made out of rocky material and sulfur. Deep inside Io is probably a core made of heavier.hat Io is Made of.
