1.	If the ice at the poles of the earth melts, how would this affect the length of the day?
Answer» Solution :If the polar ICE melts a part of the water thus produced will SHIFT from the POLES towards the equatorial region, and hence this water will shift away from the axis of rotation of the earth. Consequently themoment of INERTIA of the earth will increase. Now according to the principle of conservation of angular momentum with the increase in moment of incertia of the earth its angular VELOCITY will decrease and hence the length of the day will increase.
