The building of mountains, the formation of continents, the movement of plates take millions of years. This makes familiar human time scales -- days, months, years, decades or even centuries and millennia -- meaningless. Understanding geology does not mean just knowing the current properties of the rocks and continents at this very point in time, but having to understand the processes that made the rocks and made the continents, which requires being able to grasp the millions of years these processes have taken.
Geologists created the geologic time scale to organize Earth's history into units of time based on the sequence of events recorded in the rock layers. It helps in understanding the chronology of Earth's history, including the development of life forms and major geological events. The geologic time scale also provides a framework for dating rocks and fossils.

Which is not a major period of the geologic time scale?
Century - A century is not a major period of the geologic time scale. The major divisions of the geologic time scale are eons, eras, periods, and epochs.
In which eon of the geologic time scale means visable life?
Phanerozoic is the eon which geologic time scale means visable life.
What word represents the broadest division on a geologic time scale?
Eon is the broadest division on the geologic time scale, representing the longest time span. Eons are further divided into eras, which are then subdivided into periods, epochs, and ages.
Which is the smallest division of time on the geologic scale?
Epoch
What information does the geologic time scale provided and what are the major divisions of time?
The information the geologic scale provides is animals and fossils over time and periods. Major divisions of time is called eras.
What kind of scientists worked with geologist to develope the geologic time scale?
biologists
What methods did geologist used when they first developed the geologic time scale?
The methods the geologists used when they first developed the geologic time scale. Were studying rock layers and index fossils worldwide. By Patrick
What kind of scientists worked with geologist to develop the geologist to develop the geologic time scale?
Paleontologists, stratigraphers, and geochronologists worked with geologists to develop the geologic time scale. Paleontologists studied fossil evidence, stratigraphers looked at the layers of rock formations, and geochronologists used radiometric dating techniques to determine the age of rocks and fossils.
What information did geologist use to develope geologic time scale?
Radiometric dating and association of fossils with time scales during the periods when life existed.
What do the relative geologic time and absolute geologic time combine to form?
The geologic time scale.
What do you called the scale of time that records the events about the history of the earth?
Geologic Time. It's called the Geologic Time Scale.
Which is not a major period of the geologic time scale?
Century - A century is not a major period of the geologic time scale. The major divisions of the geologic time scale are eons, eras, periods, and epochs.
What kind of scientists worked with geologist's to develop the geologic time scale?
biologists
What unit of measurement would a geologist use for time?
Geologists measure geologic time in years.
What is a scientific time scale?
The scientific time scale is also called the Geologic time scale. It has been created to describe the order of major events on Earth for the last 4.5 billion years.
In which eon of the geologic time scale means visable life?
Phanerozoic is the eon which geologic time scale means visable life.
Why are volcanic ash deposits important to geologist?
they serve as good geologic time markers
