why are they called polar ice caps?

    It could be said that ice caps are named “caps”, because of the protective seal they put on the artic waters. For example, the ice provides a protective barrier which reflects 70% of incoming sunlight back into the atmosphere. As more of these ice caps melt, more and more sunlight will be able to absorb and warm the arctic waters. This creates what is called a “positive feedback loop”. Meaning that the melting of this ice from warming, will only create more warming and therefore sets off an irreversible cycle.

    My guess is they are called “ice caps” because they cover water and landmass like a hat or cap on top of a head (in Antartica’s case the bottom).
