太阳风的质量外流率不是固定不变的，目前太阳风的质量外流率是１０－１４Ｍθ／ａ（Ｍθ为太阳现在的质量），在１０４ａ的幼年时期，太阳风的质量外流率为１０－５～１０－６Ｍθ／ａ。因此在天文演化阶段，地球与太阳的距离比现在更近，受太阳风的作用更为强烈。对作差异旋转的地球内核而言，地质时期的太阳辐射量变化可以影响核幔角动量交换、电磁耦合和内核振动，控制核幔边界的能量交换过程，造成超级热幔柱的形成与喷发。这是天文周期与地质旋回一一对应的原因。对地球内核差异旋转的原因进行了讨论，认为它是重力分异和液核对流的结果
The mass outflow rate of the solar wind is not constant. At present, the mass outflow rate of the solar wind is 10-14 Mθ / a (Mθ is the current mass of the sun). In the early 104 a, the outflow rate of the solar wind is 10 -5 -10 - 6Mθ / a. Therefore, in the astronomical evolution stage, the distance between the earth and the sun is closer than it is now and the effect of the solar wind is stronger. For the earth core with different rotation, the variation of solar radiation during geologic period can affect the momentum exchange, electromagnetic coupling and core vibration of the mantle and mantle, control the energy exchange process at the boundary of the mantle and cause the formation and eruption of the super-hot mantle plume. This is the reason that the astronomical cycle corresponds to the geological cycle. The reasons for the differential rotation of the Earth's core are discussed as the result of gravitational differentiation and convection
