Scientists hypothesize that mass extinctions can be caused by a variety of factors, often in combination. Among the options provided, the following are commonly considered potential causes of mass extinctions:
1. **Major climate changes**: Changes in climate, such as global warming or cooling, can alter habitats and food sources, leading to species declines and extinctions.
2. **Huge clouds of dust**: This can refer to events such as asteroid impacts, which can create dust clouds that block sunlight and disrupt photosynthesis, leading to a collapse in food chains.
While violent earthquakes and rising ocean levels can contribute to environmental changes, they are not typically highlighted as primary causes of mass extinctions in the way that the other factors are. Overall, major climate changes and catastrophic events (like asteroid impacts that cause dust clouds) are often cited as significant drivers of mass extinction events in Earth's history.
