The icemass actually reflects sunlight rather then absorbs it.

The apparent movement of the sun towards the north pole stops at the tropic of cancer.Beyond that, the sun will never shine overhead.In summer, the angle of incidence of the sun's rays beyond this latitude increases towards the poles and therefore the amount of heat received on a given area decreases towards the poles.Even though the sun shines all the 24 hours throughout the summer period of six months, the amount of solar radiation received is very less due to the incresed angle of incidence of the solar radiation.
Secondly,snow is a good reflector of heat and a fairly good radiator of long-wave radiation.Consequently, the temperature over a snow surface tends to sink to very low levels.Not only this, the incident solar radiation may serve to melt the ice only, not rising its temperature at all above the freezing point.Extremely low temperatures are therefore experienced over ice and snow in polar regions.

Two reasons. One, most of the sun's heat is filtered out by the long trip through the atmosphere. The sun never gets very high in the sky near the poles. Second reason is albedo. All that ice and snow reflects a lot of the sunlight back into space.

from an alaskan yes the north pole gets 24 hr sun a day in the summer in the winter it gets 24 hrs of dark thats alot of cold that gets stored in the winter and the white of the ice doesnt absorb much heat yet there are reports from this summer that alot of open water around the pole this season global warming is a reality in the artic hope its not past the point of no return open water absorbs heat we could be in trouble

The North Pole gets 24 hours of solar from the vernal equinox (22 March) to the autumnal equinox (22 September). the two poles have an afternoon of six months and a nighttime of six months!

Poles are farther from the sun due to the curve of the planet - midsection is closer and top and bottom areas are farther

The rays just touch the pole without warming it and without stopping on it, and they fall vertically on the equator and warm it very good.
Draw the picture of the rays lighting the Earth.

Rays only touch the pole. You will not see the sun, if you lye horisontally on the pole.

Because the heat isn't enough to melt the ice.

It is tilted away from the sun

because it's melting off the cold it's had for an equally long time. duh!
