Because its whenever something drastic happens, or a dominant animal dies off and new ones come in.
Geologic units of similar ages are typically shown on a geologic map using the same color or pattern to represent them. This helps to visually differentiate between different units and understand their distribution across a region. Stratigraphic relationships and relative ages may also be indicated to show how these units are connected in terms of geologic time.
The categories in the geologic time scale include eons, eras, periods, epochs, and ages. These divisions are used to categorize the Earth's history into distinct chronological units based on significant geological and biological events. Each category represents a different scale of time, ranging from billions of years for eons to millions of years for epochs.
The Calvin scale is a temperature scale in physics defined as the kelvin temperature shifted by 273.15 units, with its zero point at absolute zero. It is no longer in common use compared to the Celsius or Fahrenheit scales.
The shortest piece of Geologic time is the Holocene Epoch in the Cenozoic Era>
Converting from a longer metric unit length to a shorter one requires multiplication because you are essentially determining how many smaller units fit into a larger unit. For example, when converting from meters to centimeters, you multiply by 100 because there are 100 centimeters in a meter. This process reflects the relationship between the units and scales the measurement up to account for the smaller unit's size.
The basic units of the geologic time scale eras and periods.

The geologic time scale spans millions to billions of years and is used to categorize Earth's history based on geological events. Time scales for human activities or accomplishments are much shorter and focus on events within human history, typically ranging from centuries to millennia. Additionally, human time scales are often culturally or socially defined, highlighting specific milestones or developments in human civilization.
geologic time scale. i got this answer from a final in my science class
Geologic Time scale
on geologic maps, geologic units are distinguished by color. UNITS OF SIMILAR ARE ASSIGNED COLOR IN THE SAME COLOR FAMILY.

It is neither longer nor shorter. Since there are no units of measurement, neither number is a length and so neither can be longer (nor shorter).
The units that divide the geologic time scale are Eons, Eras, Periods, and Epochs. Eons are the biggest, Eras are the second biggest and so on and so forth. So it goes Eons, Eras, Periods, and then Epochs. I know this because i just took a test on it in science so i know its right.
