on geologic maps, geologic units are distinguished by color. UNITS OF SIMILAR ARE ASSIGNED COLOR IN THE SAME COLOR FAMILY.

How are geologic units of similar ages shown on a geologic map?
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.

Describe how geologic units of similar ages are shown on a geologic map?
On a geologic map, units of similar ages are typically represented using distinct colors or patterns to differentiate them visually. Each color or pattern corresponds to a specific geologic formation or period, allowing for easy identification of rock types and their relative ages. Additionally, these units may be labeled with their names and age ranges, providing further context for interpretation. The map legend usually explains the color-coding and symbols used, ensuring clarity and consistency.

What are the guidelines used to determine the relative ages of the rocks and events shown by a geologic cross section?
The guidelines used to determine the relative ages of the rocks and events shown by a geologic cross-section is the Law of Superposition. It is the basic law of geochronology.

What smaller units of geologic time make up eras?
Smaller units of geologic time that make up eras include periods, epochs, and ages. These divisions help geologists to further classify and understand the history of the Earth's geological formations within each era.
How many different life ages have been identified in geologic time scale?
The geologic time scale is divided into several hierarchical units, including eons, eras, periods, epochs, and ages. There are four main eons: Hadean, Archean, Proterozoic, and Phanerozoic. Within the Phanerozoic eon, there are three eras—Paleozoic, Mesozoic, and Cenozoic—further divided into periods, epochs, and ages. Overall, hundreds of specific ages have been identified, but the exact number can vary depending on the level of detail and geographic focus.
What can geologic eras be divided into?
Geological eras can be divided into periods, epochs and ages.
In the division of geologic time scale the latest units are eons which are divided into eras eras are then divided into what?
Eras in the geologic time scale are divided into periods. Each period represents significant intervals of geological time characterized by distinct geological and biological events. Further subdivisions of periods are known as epochs, and these can be further divided into ages.
What is the third largest division of geologic time?
The third largest division of geologic time is an era. The eras are further divided into periods, epochs, and ages.
What geologic ages were Athyris alive?
Athyris was a genus of brachiopods that existed during the Carboniferous Period, specifically in the Mississippian and Pennsylvanian epochs. This places Athyris in the geologic ages of the Carboniferous Period, which lasted from approximately 359 to 299 million years ago.
