Why are geologists interested in the history of the earth?

Geologists are interested in the history of the earth because they want to know how the world became what it is today.

Who is the best geologist?

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/

Why are the eons and eras not equal in length?

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.


How geologists designate the different time periods in earths ancient past?

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.
