Description
 
Our Popular Eras of Life Geological Time Scale presents the complex life on Earth as it has evolved over the past 365 million years. This chart "zooms out" to show the big picture. It condenses the 4.6 billion years that the Earth has been around to a 24" x 36" poster.

Geologists divide the history of the earth into four eons. Each is represented by a strip of illustrations and captions prefaced by an introduction. Our planet began as a sphere of molten metal. Heavier ores sunk to the center, resulting in gravity. As Earth cooled, its crust was formed. Other topics include the creation of the moon, the appearance of various atmospheres, the formation of continents, continental drift, snowball Earth, and the development of life. The third through fifth pictures on the bottom row reflect the period covered by Eras of Life. The last picture shows the near future - the results of humans destroying the environment.

Poster is 36" x 24" and is heavily laminated.
