Yes, Europa may be rich in silicates and lightweight water ices. The surface consists of many systems of cracks, and ridges, running for thousands of miles, about 10–25 mi (16–40 km) in width. There are few elevations, and the surface is remarkably free from craters. The ice surface makes the satellite(or moon)of Jupitor one of the most reflective bodies in the solar system. Geologic activity is thought to heat the ice under the surface to near-liquid state, allowing it to gush through in volcanoes of slush and water. It is likely that liquid oceans exist on Europa at depths more than 6 mi (10 km) below the surface, kept liquid by geothermal activity and tidal action. This is suggested by the variable Europan magnetic field observed by the Galileo spacecraft. It is not inconceivable that simple life may exist in the Europan oceans, much in the same way as in Earth's oceans lifeforms congregate near thermal vents.
