If the ice at the poles melts and flows towards the equator, how will it affect the duration of day-night?

By the law of conservation of angular momentum, no external torque acts on earth. So its angular momentum is a constant ie., `I omega =a` constant. As ice meits there is redistribution of mass. Hence the MX of earth increases. So the angular velocity decreases i.e., theperiod ofrotation rincreases. i.e, duration of a day will increase.
`T = (2pi)/omega` duration of a day will increase.
