Effusive magmatism processes at early stages of planet crust forming come out in structure of solidified relief forms of Mars, Venus, Mercury and Moon. Volcanic relief of planets represents relict ancient line oriented forms, areal and central lava flooding. Linear forms generate shield volcanoes, chains of volcanic mountains and radial-concentric faults.Volcanic structure relief doesn’t give variety of structure forms development, because it shows only tectonic deformation in the nature of cavities and elevations of planet surface. Most of the above mentioned geological relief forms are of endogenous origin. Relief-forming meaning of endogenous processes is compensated by exogenous processes during long stages of planets development. Influence of exogenous factors (weathering, fall, accumulation, etc.) on the structure of planets’ relief surface is considered in the article.
