Abstract: | Glaciation between northern hemisphere and southern hemisphere were synchronous, the ice age occurred not in high but in low value of the eccentricity of the earth's orbit. Such facts went against the precession principle of the astronomical theory of ice age. The inhomogeneous distribution of climate consisted with the inhomogeneous distribution of ocean and continent. The north/south antisymmetry may be attributed to southward deviation of the thermal center and northward deviation of the mass center within the mantle demonstrated by seismic tomography. The core - mantle angular momentum makes rotational energy into thermal energy and mantle plumes erupt in the ocean bottom. The earth's deformation by tidal force makes the eruption of mantle plumes strong. They are the reason that glaciation between the Northern Hemisphere and Southern Hemisphere are synchronotis and the ice age occurred in low value of the eccentricity of the earth's orbit. The tectonic movement is playing a most important part in global climate change. |
