He polar regions radiate away more heat energy than they receive from the Sun in the course of a year. However, they are prevented from becoming progressively colder each year primarily by the absorption of ultraviolet radiation by snow A transport of heat through the atmosphere and oceans B concentration of Earth's magnetic field lines at the poles C release of latent heat to the atmosphere when the polar ice caps melt D generation of heat by glacial movement

A. transport of heat through the atmosphere and oceans

Explanation:

The polar region of the world acts as a heat-absorbing sink and they are prevented from getting progressive colder due to the impacts of the solar radiation. That transports the heat in the forms of the sir and water and thus releases of the latent heat of the water lead to the break up of the ice sheets and thus glacial ice tends to melt and float away.

May consider a group  g=({0,1},+)g=({0,1},+)where  ++  will work as the xor operator like we work in boolean algebra. note here, that ‘00’ and ‘11’ are not the usual 0 and 1 that we work with everyday. the elements are  called  ‘00’ and ‘11’ and  may not mean  zero (nothing) and one (single). ‘00’ is the identity for the given binary operator +, meaning that any element operated with ‘00’ gets us that element itself.  for a set  ss  in  g′g′  having more elements than just  {0,1}{0,1}  the values for  a+b∈sa+b∈s, such that  a∈s,b∈sa∈s,b∈s, have to be first defined, only then can you determine the value of  1+11+1. the answer could possibly have been  22  if oanswer is25,000
