The geologic time scale.

Geologic Time.

It's called the Geologic Time Scale.

Cenozoic is not a major period of the geologic time scale. The scale is broken down into eras. Cenozoic, Mesozoic and Paleozoic are all part of the Phanerozic era.

Phanerozoic is the eon which geologic time scale means visable life.

in the scope of geologic time, how significant is the presence of humans?

The Precambrian

Cenozoic

On a geologic time scale, yes. On any other time scale, no.

Eon The largest expanse of time on the geologic time scale is the eon. An eon would encompass at least two eras.

Eon The largest expanse of time on the geologic time scale is the eon. An eon would encompass at least two eras.

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.

The information the geologic scale provides is animals and fossils over time and periods. Major divisions of time is called eras.

Epoch

geologic time scale

The shortest division in the geologic time scale is an Epoch. Epochs are subdivisions of a period and are typically tens of millions of years long.

The largest expanse of time on the geologic time scale is the eon, which is further divided into eras. Eons are the longest subdivisions of time, representing billions of years of Earth's history.

sorry we dont know the answer

Because.

precambrian times

The methods the geologists used when they first developed the geologic time scale. Were studying rock layers and index fossils worldwide.

By Patrick

because the time span of earth past is so great geologic

The basic units of the geologic time scale eras and periods.

In the order of time.

Phanerozoic

By eons, eras, epochs, and periods.

Phanerozoic

This period is called holocene.

The Earth's geologic time scale spans about 4.6 billion years, from the formation of the Earth to the present day.

The four large sections on the geologic time scale are eons, eras, periods, and epochs. Each of these divisions represents a different scale of time with eons being the largest and epochs being the smallest.

The Geologic Time Scale is measured in years, often in millions or billions of years. The age of our solar system is about 4.5 billion years. The 'geo' part of the name means it refers to our Earth.

A period is smaller than an era in the geologic time scale. It is further subdivided into epochs and ages.

No such thing.

Some geometers consider time to be the fourth dimension.

There is a "geologic time scale" which is the time scale at which you notice continents moving and mountain ridges growing and being eroded (very long time scale)
