When was the last mass extinction?

How do geologists define the end of the paleozoic and mesozoic eras?
Geologists define the end of the Paleozoic Era by the Permian-Triassic extinction event, which occurred around 252 million years ago, marking a significant loss of biodiversity. The end of the Mesozoic Era is characterized by the Cretaceous-Paleogene extinction event about 66 million years ago, which led to the extinction of the dinosaurs and many other species. These boundaries are identified based on geological and fossil records, including major shifts in species composition and significant changes in Earth's climate and environments.
Was the extinction of dinosaurs caused by a comet crashing to earth?
no a dieses killed all the dinosaurs but we may never know if i am wrong or right No, The reason for their ending may be because of the Flood that happened in the Bible, If you look it up in Genesis you can read more.
What is one gradual change that can cause a mass extinction?
One gradual change that can cause a mass extinction is climate change. If the Earth's temperature rises or falls significantly over time, it can disrupt ecosystems and lead to the extinction of many species that are unable to adapt quickly enough to the new conditions. This can result in a cascading effect on other species within the ecosystem, ultimately leading to a mass extinction event.
Was the extinction of dinosaurs caused by a metoerite crashing to earth?
Most dinosaurs died off about 65 million years ago. Most life on Earth ended 65 million years ago during what is called the Cretaceous-Paleogene extinction event. There is substantial scientific evidence of an asteroid or comet impact on Earth that caused or was the primary contributor to the extinction. A few scientists still hold other views, including a massive eruption of volcanoes. See related links.
How many major extinction events have occurred during the Earth's history?
There have been five major extinction events during Earth's history. These events are known as the Ordovician–Silurian, Late Devonian, Permian–Triassic, Triassic–Jurassic, and Cretaceous–Paleogene extinction events. Each event resulted in a significant loss of biodiversity and had profound impacts on the evolution of life on Earth.
