True:
- The events were caused by changes to Earth's environment. (Mass extinctions are tied to large environmental changes — climate shifts, volcanic activity, sea‑level change, asteroid impacts, etc.)
- At least 50% of the species on Earth were destroyed during each event. (By definition the major “mass extinctions” involve very large, often ≥50%, losses of species.)
False:
- All life on Earth was destroyed — not true (many species survived).
- All the extinction events were caused by asteroid impacts — not true (only some, e.g., the end‑Cretaceous, are linked to an impact).
- Intense ice ages had the greatest impact on species extinction — not universally true; different extinctions had different primary causes.
