Question

When a volcano erupts, it results in dangerous lava and mud flows, and the ash it produces can travel hundreds of miles. Which of the following best describes an initial consequence of this catastrophic event?
Less diversity of plants
Prolonged drought
Increase in invasive species
Plant populations increase

Answer 1

The only one that best describes an initial cosequence of this catastrophic event is the first option Less diversity of plants. But few species can grow in lava. Though cold lava is hard to being fertilized for plants as it's difficult to grow roots into tough layer of the lava.
