Dear Reader,<\/p>\n

It’s officially public! Our oldest son is engaged to be married, and we couldn’t be happier. Certainly one of life’s biggest events, and a happy occasion all around. My husband and I are smiling from ear to ear. <\/p>\n

\tSee ya on the Net,

The geologic time scale (GTS) is a system used by Earth scientists to organize the timing of events in Earth’s history. The largest defined unit is the supereon, which is composed of eons. Eons are divided into eras, which are further divided into periods, epochs and ages. Because there is a relationship between these time frames and the Earth’s layers of rock, there are corresponding terms (eonothem, erathem, system, series, and stage) that refer to the matching layers of rock.<\/p>\n

Fossils Facts and Finds: Geologic Time Line

For middle-school students, this site introduces the GTS with a clickable chart. Most of the eras and periods are linked to detail pages for a deeper look. “As a reference tool, you can easily note the sequence of the various divisions and the length of each unit of time. Just like the layers of the earth, the top divisions of the chart represent the most recent time. Moving down the chart, you go further and further back in time.”<\/p>\n

Geology.com: Geologic Time Scale

Unlike hours in a day, the time intervals on the GTS are not of equal length. “Instead the time intervals are variable in length. This is because geologic time is divided using significant events in the history of the Earth.” For example, the Permian and Triassic periods are divided by a “global extinction in which a large percentage of Earth’s plant and animal species were eliminated.” In addition to the smallish graph embedded on this page, there is a printable PDF of the GTS for downloading.<\/p>\n

National Geographic: Prehistoric Time Line

This interactive, clickable timeline starts in Precambrian time. You can navigate through it with either the slider, the next\/previous buttons, or by clicking on any event that catches your eye. “Earth was created between 4.5 and 4.6 billion years ago, when our solar system took shape around the sun. Born from exploding stars called supernovae, the new star gathered a swirling disk of dust and gases around it. As the sun heated up, this orbiting matter accumulated, and successively larger bodies collided to eventually create protoplanets with their own gravitational pull.”<\/p>\n
