根据大陆、海洋分布的对称性推测火星结构

摘要

The distribution of continents and oceans on the surface of the Earth possesses obvious symmetricity:if one side is covered with a continent,then the opposite side is coveredwith ocean.The symmetricaldistribution dependson the Earth structure of sphere and layer.The sketch map is worked out by elevation data of the Mars surface from ‘Google Earth’,which helps to discover the distribution symmetricity of the continents and oceans on the surface of the Mars as compared with Earth.The structure of the Earth is lithosphere,asthenosphere solid mantle sphere,and liquid core sphere,proceeding from outer to inner.Analogously,Mars possesses the same or the similar inner structure as Earth,which is the basic mode.%地球表面大陆、海洋的分布具明显的对称性.根据Google Earth提供的火星地表高程数据粗略编制了火星大陆、海洋分布示意图,发现火星的大陆、海洋分布也具有对称性.依照类比原理,火星与地球应具有相同或相似的内部结构,即从外至内为岩石圈-软流圈-固态内核.
