However, it is possible that Venus does not have discrete core In this case the iron and silicates would be mixed throughout the planet instead Q being separated into mantle anc core The crust ranges from 25 km thick in the lowlands to 160 km thick in the highlands. This relatively thick static crust may be composed of a single plate Soil samples taken by Veneras and 10 indicate that Venus crust has composition similar to terrestrial ocean deposits surrounded plane separ ated crusi simila
