It is not diffrent since it is marked out by extinction events or other such major changes in two adjacent rock stratum (layers of rock), for example the boundaries can be distinguished by changes in the types of fossil found such as the K-T extinction event as there are no dinosaur fossils found in the layers that were deposited after the event. That said though different places have diffrent names for the same rock stratum due to several factors such as the fossils found in India will not match the fossils found in the UK much as you cannot find wild tigers in London.

How can a geological time scale BEST be reconstructed?
A geological time scale is best reconstructed using a combination of radiometric dating, fossil evidence, and stratigraphic relationships between rock layers. By utilizing these methods together, scientists can create a comprehensive and accurate timeline of Earth's geological history.
Who invented the geological time scale you know today?
The modern geological time scale, as we know it today, was developed in the 19th century by geologists Sir Charles Lyell and Sir Roderick Murchison. They were among the key figures who established the principles and framework for dividing Earth's history into distinct time periods based on rock layers and fossil evidence.
What information does the geologic time scale provide and what are the major divisions of geological time?
The geologic time scale provides a timeline of Earth's history, dividing it into periods based on significant events and changes in the planet's environment. The major divisions of geological time are eons, eras, periods, epochs, and ages, each reflecting different intervals of time with distinct characteristics and geological events.
How do geological and human time scales differ?
The geological time scale is hugely larger than the human time scale. For humans, a decade is a significant period of time, and even our civilizations span only a few thousand years... whereas in geological terms even a million years isn't that much.
What is the purpose of a geological time scale?
The reason Geologic Timescales are used are to give sense of what time begining from 4.5 billion years ago, and the satges through Evolution. That's how it's possibly percieved, I am not accuratly certain, so do research and come up with a possible answer to counter my statement.

What does one Ma on the geological time scale represent?
One million years on the geological time scale represents one million years of Earth's history. It is a unit of time used to measure and discuss long-term geological events and processes.

By which professions was the geological time scale used by?
The geological time scale was used by professions such as scientists. Scientists use this to record important life events and life forms. These are very important to humans.
Where can you find a geological time scale?
Have a look at the wikipedia link attached.
What marks the end of a geologic period?
Each era on the scale is separated from the next by a major event or change. Different spans of time on the time scale are usually delimited by major geological or paleontological events, such as mass extinctions.
