Interrelationships among the terrestrial planetsThe spatial distribution of mass in the solar system provides invaluable clues pertaining to the condensation history of the solar nebula, to the sequence of condensation of minerals and metal alloys in different P-T Regimes in the nebula and to the time sequence in the nucleation of planetary iron cores. Massive planets (Earth & Venus) were due to the twin processes of early nucleation of iron into massive cores and late termination of accretion processes which resulted in the accretion of volatile rich materials also. This paper maintains that the accretionary features (High-lands, basins/craters) are present on all the planets and the thermally controlled tectonic styles (Rifts, fracture zones, volcanic plains, Canyons, trenches, domes, etc.) are essentially of same origin but are of different magnitude and the interactions of degassed volatiles (atmosphere together with hydrosphere) with the lithosphere are dictating and diversifying the tectonic style on the Earth.
