They Are Cold
Ice caps are located on the north and south poles
Precipitation in the ice-cap climates is so little that these regions are called polar deserts. The average annual precipitation hardly exceeds 10 cm. Even though the precipitation is very low, it still exceeds evaporation.
Season And Temperature Range
There is summer and winter. The temperatures here are almost always below zero
Factors Affecting Climate
The fact that this area is on the bottom of the earth means that in the winter there is no sun. In the summer the sun never sets. This contributes to the climate.
