Geologic time scale
Geologists are interested in the history of the earth because they want to know how the world became what it is today. Geologists study the history of earth because it's a thing they've grown to like and are in to. History is a major part of earth and the way of life, someone has to know the statsitics.
A petrologist studies the history and structure of rocks. Geologists and paleontologists also have great interest in rocks.
Geologic history is divided, from largest amount of time to smallest amount of time, by eons, eras, periods, and epochs.
Your question is kind of broad since geology is comprised of such a wide spectrum of careers, but here are a few of the most renowned geologists in history: James Hutton - http://en.wikipedia.org/wiki/James_Hutton Charles Lyell - http://en.wikipedia.org/wiki/Charles_Lyell Alfred Wegener - http://en.wikipedia.org/wiki/Alfred_Wegener Here's a list of other famous geologists: http://en.wikipedia.org/wiki/List_of_geologists The majority of work that geologists perform today is based on the discoveries of these people. There are many different jobs that geologists perform today, but I'd say that the "best" geologists of today are those who dedicate their lives to the study of environmental sustainability and the prediction/prevention of geologic hazards. Geologists involved with the oil industry are generally the highest paid in the field, but some may not consider these to be the "best" geologists because of their affiliation with oil companies and how detrimental they are to the environment. Many of the best geologists today work for the U.S. Geological Survey (USGS). http://www.usgs.gov/
The science that deals with Earth's history of rocks is called geology. There are geologists that study rocks for a living.
Geologists study the origins, physical history, and structure of earth.

Geologists divide Earth's history into supereons (there's only one, the precambrian), supereons are divided into eons (there are four), eons are divided into eras, eras are divided into periods (Periods may be the most common divisions you read about. The Jurassic is a period), periods are divided into epochs, epochs are divided into ages.After the first era (the Cryptic) The various divisions are mostly determined buy the emergence of some form of life.
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.
rocks
Two things geologists study is the process that creates Earth's features and search for clues about Earth's history
fossil records
according to history, the church is really represented in adelaid.
Rock formation, layering and composition, and the plant and animal fossil record, all help to form a time-line.
Petrologists and mineralogists study rocks and minerals respectively. Earth's landforms are studied by geomorphologists.They may collectively be known as geologists.geologistsGeologistsBest answer would be the earth scientists known as geologists.
Uniformitarian geologists will use this method to determine which layer of rock formed at which time period of earth's history, and the order of the formation.
