Vedclass · Answer

(A) The moment of inertia $I$ of a body is given by $I = \sum mr^2$,where $r$ is the perpendicular distance of mass $m$ from the axis of rotation.When ice at the poles melts,the water flows from the poles towards the equatorial regions of the Earth.This causes the mass to be distributed further away from the axis of rotation (i.e.,$r$ increases).Since the mass is now distributed at a larger average distance from the axis of rotation,the moment of inertia of the Earth increases.

When ice at the poles of the Earth melts,its moment of inertia will ........ .
