Question

If the polar ice caps of the Earth were to melt, what would be the effect of the length of the day be?

Answer 1

if polar ice caps of the earth were to melt then moment of inertia would have increased as water would move to equator and as we know
I×w =constant so if I increases then w decreases and earth would take more time to rotate around its own axis so length of day would increase
HOPE IT WILL HELP U.....

Answer 2

Hii dear,

◆ Answer-
Days will be longer

◆ Explanation-
- When the ice on the polar caps melt, it will distribute the ice now at the poles all around the planet causing a change in the distribution of mass.
- Since the mass is further from the axis of rotation, the rotation slows, which means the days are longer.

Hope that is helpful...
