eras
Geological time is typically divided into units based on types of rock layers, fossils, and major events in Earth's history. The primary units of geological time are eons, eras, periods, epochs, and ages. These divisions help scientists organize and study the Earth's long history.
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.
The geological time scale is divided into: Eons (Such as the Proterozoic and the Phanerozoic) THEN Eras (Such as the Mesozoic and the Cenozoic) THEN Periods (Such as the Cretaceous and the Quaternary) THEN Series, alternatively Epoch (Such as the Pleistocene and the Holocene) THEN Stage (Such as the Campanian and the Tarantian)
The Geological eras can be divided into three major eras: Paleozoic, Mesozoic, and Cenozoic. These eras represent different periods in the Earth's history marked by significant geological and biological changes. Each era is further subdivided into periods, epochs, and ages.
The divisions of geological time, known as geologic time scales, are not standard lengths like 100 million years because they are based on significant events in Earth's history, such as mass extinctions and major geological changes, rather than a uniform passage of time. These divisions reflect the complex and uneven nature of Earth's geological and biological evolution. Additionally, the varying rates of sedimentation, tectonic activity, and biological development contribute to the irregular lengths of these divisions. As a result, some periods may last millions of years while others may only last a fraction of that time.

In Bangladesh, we have offices in all eight administrative divisions. These divisions are divided into 64 districts. Each division is named after its major city, which also serves as administrative seat.
What are the three major divisions of a speech?
The major divisions of a carcass are typically called primal cuts. These cuts are large sections that are removed from the whole carcass during butchery and can further be divided into retail cuts for sale. Examples of primal cuts include the loin, shoulder, and ribs.
Dualism and non dualism are two major divisions of philosophy.There may be different names for this divided phenomena but basically these two stands as fundamental.

The major divisions of Earth's history are typically divided into eons, eras, periods, and epochs. The current eon is the Phanerozoic, which is divided into eras such as Paleozoic, Mesozoic, and Cenozoic. Each era is further divided into periods, like the Jurassic period within the Mesozoic era. Periods can be subdivided into epochs, such as the Pleistocene epoch within the Quaternary period.
