This colorful and detailed PowerPoint explains the geologic time scale of Earth’s history. It starts with distinguishing between eons, eras, periods and epophs. It explains the major portion of Earth’s History, the Precambrian Eon and how during this time, the Earth’s land, water and atmosphere were created and preparing for life. It then goes into the Phanerozoic Eon (the eon of life) and further breaks down life during each era, period and some epochs.
