Which of the following is a typical characteristic of mass extinction events?

• A. Gradual species decline
• B. Rapid loss of biodiversity
• C. Localized habitat destruction
• D. Climatic adaptation

Answer: (B)

Mass extinction events are characterized by a rapid loss of biodiversity that affects a wide variety of species across different ecosystems. During these events, a significant percentage of all living species become extinct in a relatively short geological timeframe, which is often linked to catastrophic events such as severe climate change, asteroid impacts, volcanic eruptions, or other major environmental shifts. This sudden and widespread loss of species contrasts with more gradual or localized extinctions, where specific species may decline over a longer period or only in particular areas. Thus, the rapid nature of biodiversity loss is the defining feature of mass extinction events, highlighting the stark difference between these occurrences and other forms of extinction.
