'According to the common opinion of the Arabs, there are seven heavens, one above another, and seven earths, one beneath another; the earth which we inhabit being the highest of the latter, and next below the lowest heaven. The upper surface of each heaven and of each earth are believed to be nearly plane, and are generally supposed to be circular. Thus is explained a passage of the Koran in which is said that God has created seven heavens and as many earths or storeys of the earth. Traditions differ respecting the fabric of the seven heavens. In the most credible account, according to a celebrated historian, the first is described as formed of emerald; the second of white silver; the third of large white pearls; the fourth of ruby; the fifth of red gold; the sixth of yellow jacinth; and the seventh of shining light. Some assert Paradise to be in the seventh heaven; indeed, I have found this to be the general opinion of my Muslim friends; but the author above quoted proceeds to describe, next above the seventh heaven seven seas of light, then an undefined number of veils or separations of different substances seven of each kind, and then Paradise, which consists of seven stages one above another (these are distinguished by the names of precious gems) canopied by the Throne of the Compassionate. These several regions of Paradise are described in some traditions as forming so many degrees, or stages ascended by steps.'
'The earth is believed by the Arabs to be surrounded by the ocean, which is described as bounded by a chain of mountains called Kaf, which encircles the whole as a ring, and confines and strengthens the entire fabric; these mountains are described as composed of green chrysolite like the green tint of the sky. Mecca, according to some, or Jerusalem, according to others, is exactly in the centre. The earth is supported by successive creations one beneath the other. The earth is upon water, the water upon the rock, the rock on the back of the bull, the bull on the bed of sand, the sand on the fish, the fish upon a still suffocating wind, the wind on a vale of darkness, the darkness on a mist, and what is beneath the mist is unknown. It is believed that beneath the earth and the seas of darkness is Jahennem, which consists of seven stages, one beneath another.'
precambrian era, paleozoic era, mesozoics era, cenozoic era
The geologic time scale is divided into four eras: the Precambrian, Paleozoic, Mesozoic, and Cenozoic eras. Each era represents a distinct span of time in Earth's history with characteristic geological and biological features.
The layers of rock that indicate Earth's eras are divided into three main types: igneous, sedimentary, and metamorphic rock layers. By studying the rock layers and the fossils contained within them, scientists can determine the different eras of Earth's history, such as the Paleozoic, Mesozoic, and Cenozoic eras. Each era is characterized by distinct types of fossils and geological features preserved in the rock layers.
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 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.

This question needs to be more specific. Life in different eras was different...but perhaps provide specific eras for a better result.
The four eras of business are natural resources, capital, personal resources, and entrepreneurship. The factors of production have changed through these eras by what drives the business will change.

There are so far 4 Eras in the earths history. the one that started the beginning if the earths history: Precambrian Time. The one after that was the Paleozoic Era, which means "ancient life." next was mesozoic which means "middle life" the one we are in is called the Cenozoic Era which means" recent life." * All Eras ended with a mass extinction.

The four eras of geologic time are the Precambrian, Paleozoic, Mesozoic, and Cenozoic. These eras represent significant periods in Earth's history, each characterized by distinct geological and biological events.
