Introduction to the Geologic Eras & the Paleozoic Era Ms. Stottlemyer 6th Grade Science Motion (Basic) Note: This video template is optimized for Microsoft PowerPoint 2010. In PowerPoint 2007, video elements will play, but any content overlapping the video bars will be covered by the video when in slideshow mode. In PowerPoint 2003, video will not play, but the poster frame of the videos will remain in place as static images. The video: Plays automatically after each slide transition. Is 15 seconds long. Seamlessly loops for infinite playback. To add slides or change layout: To add a new slide, on the Home tab, in the Slides group, click the arrow under New Slide, then click under Motion Background Theme, then select the desired layout. To change the layout of an existing slide, on the Home tab, in the Slides group, click Layout, then select the desired layout. Other animated elements: Any animated element you insert will begin after the slide transition and the background video has started.

The Geologic Timescale

The Geologic Time Scale Scientists examine changes in rock formations to determine different time periods on planet Earth. The geologic time scale examines when different types of plants and animals appeared and disappeared from Earth. Geologic time is broken down into eons, eras, periods, epochs and ages.

Smallest Amount of Time Geologic Time Scale Eon Era Period Epoch Age Largest Amount of Time Typically only used for the Cenozoic Era Smallest Amount of Time

Geologic Time Scale Terms EON: Two or more geological eras form an Eon, which is the largest division of geologic time, lasting many hundreds of millions of years. ERA: Two or more geological periods comprise an era, which is hundreds of millions of years in duration. PERIOD: The period is the basic unit of geological time in which a single type of rock system is formed, lasting tens of millions of years. Definitions are from enchantedlearning.com

Geologic Time Scale Terms EPOCH: An epoch is a division of a geologic period; it is the smallest division of geologic time, lasting several million years. AGE: An age is a unit of geological time which is distinguished by some feature (like an Ice Age). An age is shorter than an epoch, usually lasting from a few million years to about a hundred million years. Definitions are from enchantedlearning.com
