Physical Geology
Mass extinction refers to a significant and rapid decrease in the diversity and abundance of life on Earth, marked by the loss of a large percentage of species in a relatively short geological time frame. These events are often associated with dramatic changes in environmental conditions, such as volcanic eruptions, asteroid impacts, or drastic climate shifts, which can disrupt ecosystems and lead to widespread extinction. Understanding mass extinctions is crucial as they have shaped the evolution of life and influenced the geologic time scale.
