∙ 11y agoBackground extinctions are typically caused by natural events such as climate change, volcanic eruptions, or asteroid impacts. Mass extinctions are often attributed to catastrophic events like major asteroid impacts, volcanic eruptions, or significant climate change, which cause widespread disruption to ecosystems and species. Human activities, such as habitat destruction, pollution, and overexploitation of resources, can also contribute to both background and mass extinctions.
Many scientists believe that something other than asteroids have caused most catastrophic extinctions because some events, like the Permian extinction, show multiple stressors occurred simultaneously. The Deccan Traps volcanic eruptions coincide with the extinction of dinosaurs, suggesting a connection. Additionally, gradual environmental changes and feedback loops could have contributed to mass extinctions more than singular events like asteroid impacts.

There have been five mass extinctions in the past 4 billion years on Earth. These events resulted in the widespread loss of species and fundamentally reshaped the evolution of life on our planet.
The extrinsic catastrophist theory of comets suggests that comets originate from outside the solar system and are responsible for catastrophic events on Earth, such as mass extinctions. This theory proposes that comets carry organic materials that may have influenced the development of life on Earth.

Major catastrophic events such as asteroid impacts and volcanic eruptions have caused mass extinctions in Earth's history, leading to the extinction of numerous species. These events have also shaped the evolution of surviving species and influenced the overall biodiversity on the planet. Additionally, catastrophic events like earthquakes and tsunamis can disrupt ecosystems and human communities, causing widespread destruction and loss of life.

mass extinction events throughout history. These craters provide evidence of the catastrophic effects of asteroid or comet impacts on the Earth's surface, leading to significant environmental changes and extinction events. Scientists study these craters to better understand the impact events and their potential implications for future planetary protection.
The outcomes of each of the mass extinctions is that animal and/or bacteria die.

Catastrophists studying geology must make the major speculation that geological events in the past were primarily the result of sudden and catastrophic events rather than slow and gradual processes. They believe that major geological processes, such as the formation of mountains or the occurrence of mass extinctions, were mostly caused by sudden and catastrophic events, such as asteroid impacts or large-scale volcanic eruptions.
No, they are fundamental to the process of evolution. Mass extinctions are less common.
