Assertion: If ice cap of the pole melts, the day length will shorten. Reason: Ice will flow towards the equator and decrease the moment of inertia of the earth. This increases the frequency of rotation of the earth.

If the ice cap of the poles melts, ice will flow towards the equator, and will increase the moment of inertia of the earth thereby decreasing its frequency of rotation. Due to decrease of the frequency of rotation, the day length increases.
