16.1 Glacial Periods in Earth’s History. We are currently in the middle of a glacial period (although it’s less intense now than it was 20,000 years ago) but this is not the only period of glaciation in Earth’s history; there have been many in the distant past, as illustrated in Figure 16.2.

Zaman es dimulai sekitar 40 juta tahun silam, dan kemudian mencapai puncaknya pada akhir Pliosen. Wilayah kutub telah mengalami siklus glasiasi dan pencairan es berulang kali, yang berulang setiap 40.000-100.000 tahun. Periode glasial terakhir pada zaman es berakhir sekitar 10.000 tahun yang lalu. [3] Referensi ^ Morbidelli, A.; et al. (2000).

Formal geologic time begins with the Archean Eon (4.0 billion to 2.5 billion years ago) and continues to the present day. Modern geologic time scales also include the Hadean Eon (4.6 billion to 4.0 billion years ago). For the purposes of geology, the “calendar” is the geologic time scale.

That’s because Earth’s timeline of natural change is episodic. That means changes happen in spurts, rather than at some slow and steady pace. Take the Precambrian Era. It lasted more than 4 billion years — or for more than 90 percent of Earth’s history. It ran from Earth’s formation until life burst out some 542 million years ago.
