The earth has gone through those periods, and the earth has gone through several epochs

Before the Aurora, about 600 million years ago, we didn't know the Earth's climate. From the Aurora period of the Paleozoic Era 600 million years ago to the Quaternary period of the Cenozoic Era 10,000 years ago, the Earth's climate has experienced three major glacial climates. The first was the Great Ice Age of the Sinian Period, about 600 million years ago; the second was the Carboniferous-Permian glacial period in the late Paleozoic era, about 230 million years ago. The third is the Quaternary Great Ice Age of the Cenozoic Era, about 2 million years ago.

The time cycle scale of these three glacial climates is about 10 million to 100 million years. During the Great Ice Age, we know for sure that the climate alternated between cold and warm. The number of glaciers moving and retreating around the world during this time is not consistent, but most scholars agree that there were four ice ages.

The earth has gone through 15 epochs so far. They are the Early Rain Sea Age of the Plutozoic, the Precambrian of the Archean, the Late Precambrian of the Proterozoic, and the Paleozoic.

of Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian, Mesozoic Triassic, Jurassic.

Cretaceous, as well as the Paleogene, Neogene, and Quaternary of the Cenozoic Era.

The Earth has gone through several epochs.

The Early Rain Age refers to a period of 50 million years from about 3.8 billion years ago. At this time, the atmosphere.

The water in the sky is constantly falling, and the ocean and other waters appear on the earth, hence the name "early rain sea generation".

The Precambrian period was from the birth of the earth to 600 million years ago, and there were no many kinds of organisms on the earth. The beginning of the Cambrian period marked a new phase of the great biological flourishing of the planet.

The Earth has gone through five epochs. Archean, Proterozoic, Paleozoic, Mesozoic, Cenozoic.

The Paleozoic Era is further divided into: Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian.

The Mesozoic Era is further divided into: Triassic, Jurassic, and Cretaceous.

The Cenozoic is further divided into: Tertiary and Quaternary.

Archean

The Archean geological record is fragmented and fragmented. However, Archean is also a critical period in the evolution of the earth, and the formation of the earth's lithosphere, hydrosphere, atmosphere and life all occurred in this important and long period, about 3.9 billion years ago, the earth formed the first permanent crust, and the atmosphere and seawater began to form 3.5 billion years ago.

Archean is the geological epoch that followed the Plutozoic and was the first to be officially recognized. It began at 3.8 billion years ago and ended at 2.5 billion years ago, giving way to the Proterozoic. During the Archean period, the Earth's crust was roughly formed and plate tectonic movement began.

3.5 billion years ago, primitive life forms: bacteria and algae first appeared on Earth.

The earth has experienced a total of 16 periods, namely: Precambrian, Cambrian, Ordovician, Silurian, Devonian, Early Carboniferous, Late Carboniferous, Permian, Triassic, Jurassic, Late Jurassic, Cretaceous, Eocene, Miocene, Late Miocene, Late Glacial Hail Age, and the modern world.
