The polar asymmetry of planets as a measure of their evolution
Abstract
Polar asymmetry is the asymmetry in geological structure between the northern and southern hemispheres of a planet. For the earth it is revealed in the granite and basalt layers of the earth crust which predominate in the Northern Hemisphere, and in the asymmetrical distribution of active volcanoes and earthquake epicenters. For the moon the polar asymmetry is revealed in the predominance of dark maria, with a basalt-like structure, in the northern hemisphere. Analogous asymmetries are considered for Mercury, Mars, and the satellites of Jupiter.
