What are the four geologic time scale eras from oldest to most recent?
The 4 eras are Cenozoic era, the mesozoic era, the paleozoic era, and the precambrian era.
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.
What is the largest division of time on geologic time scale?
Eon
What are four large section on the geologic time scale called?
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.
What is a division on the geologic time scale?
The divisions of the geologic time scale are divided into four eras. from earliest to closer to the present is the Precambrian, Paleozoic, Mesozoic, Cenozoic. During these time periods, there were several major evolutionary events. Most commonly known are the dinosaurs and humans. Hope that helped :)
