The era during which approximately 90 percent of life on Earth died out is known as the Permian-Triassic extinction event, which occurred around 252 million years ago. This event marks the boundary between the Permian and Triassic periods and is considered the most severe extinction event in Earth's history, leading to the loss of a vast number of species across various ecosystems. Factors contributing to this mass extinction likely included volcanic activity, climate change, and changes in ocean chemistry.
The Mesozoic Era is divided into three periods: the Triassic, Jurassic, and Cretaceous. This era, often referred to as the "Age of Reptiles," is known for the dominance of dinosaurs and the development of early mammals and birds. Each period is characterized by distinct geological and biological changes, marking significant evolutionary developments in Earth's history.
René Descartes' mother, Jeanne Brochard, died shortly after giving birth to him in 1596. The cause of her death is believed to be complications related to childbirth, which was common in that era. Descartes was raised primarily by his father and later sent to live with a guardian. Her death had a profound impact on him, influencing his views on life and knowledge.
Nolan Ryan had a career ERA of 3.19
because, during the slave trade americans and british people took people from africa to brazil and other places to work on plantations. many africans stayed in brazil after the slave era because they liked the surroundings and the history :)
The 300 years of business history can be broadly divided into three areas: the pre-industrial era, the industrial era, and the post-industrial era. The pre-industrial era focuses on trade and craft economies, the industrial era marks the rise of mass production and technological advancements, and the post-industrial era emphasizes service economies and digital innovations. Each period reflects significant shifts in economic practices, technological development, and societal impacts on business.
The Precambrian era spans about 87 percent of Earth's history. It includes the Hadean, Archean, and Proterozoic eons and is characterized by the formation of Earth, the development of early life forms, and significant geological events.
Cenozoic era
The Precambrian era makes up about 90 percent of Earth's history. It spans from the formation of Earth around 4.6 billion years ago to the beginning of the Phanerozoic eon around 541 million years ago. It is characterized by the development of the Earth's atmosphere, oceans, and the emergence of life.
End of the Paleozoic era
The Precambrian Era. Basically, the only life present in Earth was that of single-celled bacteria.
After the dinosaurs died out came the era of mammals.
Yes there was life , it was Mesozoic Era .
Cenozoic era
This word is from Latin meaning "middle life" because this was the second era out of the three in the eon of animal life on Earth. It is also called the "age of the dinosaurs."
The Precambrian era makes up about 88 percent of Earth's history. It started with the formation of the Earth around 4.6 billion years ago and lasted until about 541 million years ago.
The Precambrian era was a geological period that spanned from about 4.6 billion years ago to around 541 million years ago. It encompasses the earliest part of Earth's history, including the formation of the planet and the evolution of life forms. The Precambrian era was followed by the Paleozoic era, which marked the beginning of complex life on Earth.
