_{Whatever their type , most glaciers are remnants of great shrouds of ice that covered the earth eons ago. In a few of these glaciers the oldest ice is very ancient indeed; the age of parts of the Antarctic sheet may exceed 500000 years. Oxygen was absent in this eon as well. The crust of the Earth started cooling, which further led to the formation of the continents. The carbon dioxide was dissolved in the ocean water, surging its acidity. The end of the eon witnessed the formation of plate tectonics which shares similarities with the modern Earth. Water was found in liquid form.The Phanerozoic is subdivided into three eras, from oldest to youngest they are Paleozoic (“ancient life”), Mesozoic (“middle life”), and Cenozoic (“recent life”) and the remaining three chapter headings are on these three important eras.
