A glaciation (a created composite term meaning Glacial Period, referring to the
Period or Era of, as well as the process of High Glacial Activity), often
called an ice age, is a geological phenomenon in which massive ice sheets form
in the Arctic and Antarctic and advance toward the equator. Conversely, the
term interglacial or Interglacial Period, such as the current era, is used to
denote the absence of large-scale glaciation on a global scale ¿ i.e., a
non-Ice Age. Interglacials are, in general, shorter than glacial epochs.
