True or false: at 70∘n, earth's emitted infrared energy is greater than its absorbed solar energy.

False

Explanation:

No as at such a high altitude the atmosphere is composed of a stratified layer of air this region thus gets less heat from the sun and thus less energy is produced to reflect out of this system. Out of the 51% of units that fall on the earth surface, 23 units get separated and as the 30 % of energy is given off by cloud cover the land surface ice reflects about 6 and the other 50 % is being reflected by the seawater ice. Oceanic ice absorbs about 0.1 to 0.95 % of the energy that is given the form of short wave sat the outer surface and thus is unable to produce that same amount through the long waves.
