Surface Forms
Morphology
glaciation = glaciate (transparent) = glaci + ation
Formed by a standard nominalizing suffix (-ation) on the glaci- base/verb, so the meaning 'process/state related to glaciers' is directly derivable.
Etymology
Glaciation comes from the word glacier, which comes from the Latin glacies meaning 'ice'. So glaciation is when ice covers and moves over the land, shaping valleys and leaving big marks on the landscape.
