Exploring+Geologic+Time

=Earth's Geologic History - Exploring Deep Time Project = __Introduction __ The fossil record chronicles macroevolution, the creation of biological diversity through speciation. Tracing evolutionary history requires studying the archive of fossils contained in rock strata not only in one local area, but from many sites around the world. Geologists have established a geologic time scale of chronological measurement that uses stratigraphy to establish the timing of events that have happened on the Earth. If you would like to read more about stratigraphy and the dating methods used by geologists, visit the USGS site listed in the resource section below. The geologic time scale is broken into major groupings called eons. Eons are further divided into eras, periods, and epochs. Most scales are designed to fit on one page do not do justice to the immense amount of time that has passed during some time period. Eras are marked by mass extinctions when many forms of life disappeared from the fossil record and were replaced by species that diversified from the survivors. Lessor extinctions and geologic events make up the boundaries of the periods of an era.



__Assignment Summary__

Your assignment is to create a dynamic presentation about a geologic time period that describes the climate, landforms, geologic events, and the flora and fauna of that period. We will use Prezi, a web based tool that allows you to organize information in a unique web-like presentation that can utilize, images, text, and video.

__**Presentation Requirements**__-

Sample Prezi about Geologic Time

__**Embed Your Prezi**__
1. Click on the "Geologic Time Presentations" page on the navigation menu on the left. 2. Click edit. 3. On the editor bar, click on "widget." 4. Scroll down the left side of the wikispace widget page to "other HTML." 5. Paste the embed code from your Prezi into the text box provided. 6.

__Online Resources for Geologic Time__
The Paleontology Portal:Website run supported by several paleontology organizations. Contains detailed information on what North America was like during each geologic time period. Tabs for fossils and flora and fauna as well.

Geologic Time- The Changing of a Changing EarthWebsite run by the Smithsonian National Museum of Natural History. An excellent resource that can be navigated with a sliding time line followed by specific content and evidence menus for each time period along the right hand side of the page.

Tour of Geologic Time: Website run by University of California Museum of Paleontology. Has a clickable time table that takes you to an overview of each time period. Menu buttons on the bottom of the page allow you to look at specific information about each time period.

Prehistoric Time Line: Website run by National Geographic. Sliding navigation bar to each time period.

USGS Geology in the Parks: An excellent resource on geologic time, dating techniques, time lines, and PALEOMAPS!
