内容記述 | Rotational motion of a rigid sphere placed in gravity and temperature fields is studied in the hope of getting some clue as to time-dependent mantle convection. The estimate of mechanical couple exerted to the sphere due to thermal expansion leads to an equation of motion which is given in a form of non-linear integral equation provided proper account is taken of heat conduction. Solving numerically the integral equation thus obtained, it is found that the sphere overturns in a way studied by Griggs. For cells having radii of 100 and 1000 km, the rapidly accelerating period is estimated to last some 108 and 106yrs respectively. The effect of heat conduction is serious for a small cell of which the radius is of the order of 100 km, while it can be ignored for a cell having a radius of 1000 km or more. | |||||
