Civil Rights Movement Timeline (14th Amendment, 1964 Act, Human Rights Law) Jan. 23 The 24th Amendment abolishes the poll tax, which originally had been instituted in 11 southern states after Reconstruction to make it difficult for poor blacks to vote. Summer The Council of Federated Organizations (COFO), a network of civil rights groups that includes CORE and SNCC, launches a massive effort to register black voters during what becomes known as the Freedom Summer. It also sends delegates to the Democratic National Convention to protest—and attempt to unseat—the official all-white Mississippi contingent. July 2 President Johnson signs the Civil Rights Act of 1964. Aug. 4 (Neshoba Country, Miss.)
Prehistory Prehistory (meaning "before history", or "before knowledge acquired by investigation", from the Latin word for "before," præ, and historia) is the span of time before recorded history or the invention of writing systems. Prehistory refers to the period of human existence before the availability of those written records with which recorded history begins.[1] More broadly, it can refer to all the time preceding human existence and the invention of writing. The notion of "prehistory" began to surface during the Enlightenment in the work of antiquarians who used the word 'primitive' to describe societies that existed before written records.[2] The first use of the word prehistory in English, however, occurred in the Foreign Quarterly Review in 1836.[3] The occurrence of written materials (and so the beginning of local "historic times") varies generally to cultures classified within either the late Bronze Age or within the Iron Age.

Geology Entrance You might wish to start in the Cenozoic Era (65 million years ago to the present) and work back through time, or start with Hadean time (4.5 to 3.8 billion years ago) and journey forward to the present day. No matter "when" you start, don't forget to stop along the way to learn about the stratigraphy, ancient life, fossil localities, and tectonics of the various time periods. Here are three links that can help to speed your journey: 1) Get helpful hints on navigating the Geology Wing. 2) Read about the history of the geologic time scale, and find out more about how it is organized. 3) Jump to a specific time period using the UCMP Geological Time Machine. Last but not least, don't forget to visit our exhibit on Plate tectonics, an important geological concept in any time period!
Brief Timeline of American Literature and Events, 1620-1920 Brief Timeline of American Literature and Events: Pre-1620 to 1920 This timeline provides a short chronology of events in American history and literature. It is linked to course pages and bibliographies as well as to a set of more general linked resources: pages on American authors, literary movements, and American literature sites. Each author page contains a picture (if available), a bibliography (if available), links to major sites about the author, and links to works online.
Geologic time scale The geologic time scale (GTS) is a system of chronological measurement that relates stratigraphy to time, and is used by geologists, paleontologists, and other earth scientists to describe the timing and relationships between events that have occurred throughout Earth's history. The table of geologic time spans presented here agrees with the nomenclature, dates and standard color codes set forth by the International Commission on Stratigraphy. Evidence from radiometric dating indicates that the Earth is about 4.54 billion years old. The geology or deep time of Earth's past has been organized into various units according to events which took place in each period. Different spans of time on the GTS are usually delimited by changes in the composition of strata which correspond to them, indicating major geological or paleontological events, such as mass extinctions.

Food Timeline: food history research service History of the Earth The history of the Earth concerns the development of the planet Earth from its formation to the present day.[1][2] Nearly all branches of natural science have contributed to the understanding of the main events of the Earth's past. The age of Earth is approximately one-third of the age of the universe. An immense amount of biological and geological change has occurred in that time span. The first life forms appeared between 3.8 and 3.5 billion years ago. Geological change has been constantly occurring on our planet since the time of its formation and biological change since the first appearance of life. Geological time, condensed in a diagram displaying the relative lengths of the eons of Earth's history Geologic time scale[edit] The history of the Earth is organized chronologically in a table known as the geologic time scale, which is split into intervals based on stratigraphic analysis.[2][6] A full-time scale can be found at the main article.

Geologic Time Scale - Geological Time Line - Geology.com Dividing Earth History into Time Intervals Geologists have divided Earth's history into a series of time intervals. These time intervals are not equal in length like the hours in a day. Instead the time intervals are variable in length. This is because geologic time is divided using significant events in the history of the Earth. Examples of Boundary "Events" For example, the boundary between the Permian and Triassic is marked by a global extinction in which a large percentage of Earth's plant and animal species were eliminated. Eons are the largest intervals of geologic time and are hundreds of millions of years in duration. Eras Eons are divided into smaller time intervals known as eras. Periods Eras are subdivided into periods. Epochs Finer subdivisions of time are possible and the periods of the Cenozoic are frequently subdivided into epochs. Our geologic time scale was constructed to visually show the duration of each time unit. Contributor: Hobart King More Geologic Time Scale Resources
