User: Cretaceous-Tertiary

Weegy: The Cretaceous?Tertiary extinction event, which occurred approximately 65.5 million years ago (Ma), was a large-scale mass extinction of animal and plant species in a geologically short period of time. [ Widely known as the K?T extinction event, it is associated with a geological signature known as the K?T boundary, usually a thin band of sedimentation found in various parts of the world. K is the traditional abbreviation for the Cretaceous Period derived from the German name Kreidezeit, and T is the abbreviation for the Tertiary Period (a historical term for the period of time now covered by the Paleogene and Neogene periods). The event marks the end of the Mesozoic Era and the beginning of the Cenozoic Era.[1] With "Tertiary" being discouraged as a formal time or rock unit by the International Commission on Stratigraphy, the K?T event is now called the Cretaceous?Paleogene (or K?Pg) extinction event by many researchers.[2] ]

User: Select all of the answers that apply. The Cretaceous-Tertiary extinction, the most famous of the Big Five, has been attributed to what major event(s) that triggered the extinction of the dinosaurs? an asteroid hitting the earth massive volcanoes erupting around the world rapid growth of forests on land surfaces falling sea levels increased competition from mammals

Weegy: Two prominent theories of extinction are climate change and an asteroid hitting the Earth.

User: worst mass extinction in Earth's history

Weegy: Despite some controversial evidence that an asteroid or comet caused the worst mass extinction in history, [ most researchers now believe a combination of volcanic activity and a warming climate was the cause. New research announced today further supports this majority view. The Great Dying, as it is called, occurred 250 million years ago, at the end of the Permian Era. More than 90 percent of all species were wiped out. That much is well documented in the fossil record. ]
