Which eras ended with a mass extinction?
Two major eras that ended with mass extinctions are the Permian-Triassic extinction event, which marked the end of the Permian period, and the Cretaceous-Paleogene extinction event, which marked the end of the Cretaceous period. These events had profound impacts on life on Earth, leading to the loss of a significant number of species.
What were the major geologic event in the Pliocene?
One of the major geologic events during the Pliocene Epoch was the joining of the North American and South American tectonic plates. This joining formed the Isthmus of Panama separating the Atlantic and Pacific Oceans. This affected both land animals and marine life.
The major divisions in geologic time are?
The major divisions in geologic time are eons, eras, periods, epochs, and ages. These divisions are based on significant changes in the Earth's history, such as mass extinctions or the appearance of new life forms. Geologists use these divisions to organize and study the vast timeline of Earth's history.

What is the purpose of the geologic time scale?
The geologic time scale is a system used to categorize and compare the Earth's history. It helps scientists understand the sequence of events that have shaped our planet over billions of years by dividing time into distinct units based on significant geological or biological events. It provides a framework for organizing Earth's history and helps geologists correlate rock layers and fossils globally.
What were the major geologic events of devonian period?
there was plate tectonic movement
What were the major geologic events in Jurassic time period?
The existence and extinction of the dinosaurs.
What were the major geological events in the permian time period?
The major geological events in the Permian period include the assembly of the supercontinent Pangaea, widespread glaciation in the southern hemisphere, and the formation of the Siberian Traps volcanic province, which led to significant climate change and a mass extinction event known as the Permian-Triassic extinction.
What were major geological events of the quaternary period?
Some of the major geologic events include ice ages, the formation of the great lakes, and the continents moving to where they are now.
What were some major events in the Permian time period?
During the Permian period, Earth experienced the formation of the supercontinent Pangaea, extensive glaciation in the southern hemisphere, and the diversification of reptiles. The Permian-Triassic extinction event, the largest mass extinction in Earth's history, occurred at the end of the period, resulting in the loss of around 90% of marine species and 70% of terrestrial species.
Which is not a major period of the geologic time scale?
Cenozoic is not a major period of the geologic time scale. The scale is broken down into eras. Cenozoic, Mesozoic and Paleozoic are all part of the Phanerozic era.
What were the major geologic events of the Quantenary period?
Mainly the ice age. I have a project in which I have to make a PowerPoint presentation for one of the times and i chose quantenary and we are in the quantenary period right now
The ends of the geologic eras such as the Paleozoic and Mesozoic are marked by?
mass extinction events, such as the Permian-Triassic and Cretaceous-Paleogene extinctions, that wiped out a significant portion of species on Earth. These events led to major shifts in the Earth's ecosystems and paved the way for new species to evolve in the following eras.
What were the major geologic events of the mississippian time period?
During the Mississippian Period, major geologic events included the widespread deposition of carbonate rocks forming thick limestone layers, the development of large coral reefs, and the formation of coal deposits from plant materials in swampy environments. Additionally, tectonic activity led to the uplift of mountain ranges and the creation of rift basins.
What was the major geologic event during the Jurassic period?

What are the major geologic events in the triassic period?
Not much happened really except i think it was climate change and small dinos running around, the size of a chicken. (No im not kidding)
