The surfaces of the inner, terrestrial planets of our solar system are composed of volcanoes, craters, canyons, and mountains.
The interstitial planets are made up of rocks, silicates, minerals, carbon or in case of earth water as well. Generally the planets have an inner core made up of iron which is further surrounded by a mantle.
Our earth is the only planet in the universe which is found to have water at its surface while the planet Mars also has polar ice caps which are permanent just like our earth. The inner terrestrial planets consist of mercury, Venus, earth, and Mars.
