EarthViewer Mass Extinctions Answer Key: A Comprehensive Guide
Mass extinctions have been pivotal events in Earth's history, shaping the diversity of life we see today. The EarthViewer tool, developed by the Howard Hughes Medical Institute, provides an interactive way to explore these events. This guide offers an in-depth look at the mass extinctions covered in EarthViewer, providing an answer key to help students and educators understand the complexities of these catastrophic events.
The Big Five Mass Extinctions
The Earth has experienced five major mass extinctions, each wiping out a significant portion of life on the planet. These events are known as the Ordovician-Silurian, Late Devonian, Permian-Triassic, Triassic-Jurassic, and Cretaceous-Paleogene extinctions. EarthViewer allows users to visualize these events and their impact on biodiversity.
Ordovician-Silurian Extinction
The Ordovician-Silurian extinction occurred around 443 million years ago and is believed to have been caused by a combination of factors, including glaciation and a drop in sea levels. This event wiped out about 85% of marine species, marking the end of the Ordovician period and the beginning of the Silurian period.
Late Devonian Extinction
The Late Devonian extinction, which took place around 375 million years ago, is one of the least understood mass extinctions. It is thought to have been caused by a combination of factors, including climate change, anoxia, and volcanic activity. This event had a significant impact on marine life, particularly on reef-building organisms.
Permian-Triassic Extinction
The Permian-Triassic extinction, also known as the Great Dying, occurred around 252 million years ago and is the most severe mass extinction in Earth's history. It wiped out about 96% of marine species and 70% of terrestrial vertebrate species. The causes of this extinction are still debated, but volcanic activity, climate change, and anoxia are among the leading theories.
Triassic-Jurassic Extinction
The Triassic-Jurassic extinction occurred around 201 million years ago and marked the end of the Triassic period and the beginning of the Jurassic period. This event wiped out about 80% of species, including many marine reptiles and large amphibians. The causes of this extinction are thought to include volcanic activity and climate change.
Cretaceous-Paleogene Extinction
The Cretaceous-Paleogene extinction, which occurred around 66 million years ago, is the most well-known mass extinction, as it marked the end of the dinosaurs. This event is believed to have been caused by the impact of a large asteroid, as well as volcanic activity and climate change. It wiped out about 75% of species, including all non-avian dinosaurs.
