Which time period began when earth formed and ended about 542 million years ago representing about 88 of earth geologic time?
The time period you're referring to is the Precambrian, which began with the formation of Earth around 4.6 billion years ago and lasted until approximately 542 million years ago. This vast span of time encompasses the Hadean, Archean, and Proterozoic eons, during which the planet's crust cooled, life began to evolve, and atmospheric conditions changed significantly. The Precambrian represents about 88% of Earth's geological history, setting the stage for the Cambrian Explosion that marked the beginning of abundant and diverse life forms.

The Triassic period came before the Jurassic period in geologic time. The Triassic period lasted from around 251 million to 201 million years ago, followed by the Jurassic period, which lasted from around 201 million to 145 million years ago.
Is one million years sufficiently long to be considered a period of geologic time?
Yes, one million years is a significant period in geologic time. It is equivalent to 1/485th of the age of the Earth (4.54 billion years). In the geologic time scale, it falls within the Quaternary period, which includes the most recent 2.6 million years of Earth's history.
What was the geologic time period of ordovican?
The Ordovican period was in the Paleozoic era, and occurred between 488.3 million years ago and 443.7 million years ago.
Which period represents the last 2 million years of geologic time?
The last 2 million years of geologic time is represented by the Quaternary period. It is characterized by repeated glaciations and interglacial periods, shaping the Earth's surface as we know it today.
In what geologic period did the raptor live?
The Velociraptor lived in the late Cretaceous Period, about 75-70 million years ago.
What period represents the last 2 million years of geologic time?
The last 2 million years of geologic time is part of the Quaternary Period, which is characterized by major advances and retreats of continental ice sheets, as well as the evolution and dispersal of humans.
In which geologic period did pangaea form?
Pangaea, the supercontinent, formed during the late Paleozoic era, specifically during the Permian period, around 335 million years ago. The process of Pangaea's formation is known as the "assembly" phase of the supercontinent cycle.
What's the vendian period?
The Vendian Period, also known as the Ediacaran Period, was the final geologic period of the Neoproterozoic Era before the Cambrian Period. It lasted from about 635 million to 541 million years ago and is known for the appearance of complex multicellular life forms, including the earliest known animals.
What are the units of geologic time from shortest to longest?
The units of geologic time, from shortest to longest, are as follows: epoch, period, era, and eon. An epoch is the smallest unit, representing a subdivision of a period, which is a division of an era. Eras are then grouped into eons, the largest units of geologic time that encompass significant spans of Earth's history.
What is the during which geologic period did all three fossils form?
To accurately answer your question, I would need to know which specific fossils you are referring to, as different fossils can originate from various geologic periods. If you provide the names of the fossils or their characteristics, I can help identify the geologic period during which they formed.
When was chalk formed?
Most chalk was formed in the Cretaceous period, from about 138 million to 65 million years ago.
