When a volcano erupts, it results in dangerous lava and mud flows, and ash it produces can travel hundreds of miles which of the following best describes an initial consequence of this catastrophic event? a) less diversity of plants b) prolonged drought c) increase in invasive species d) plant populations increase i know it is not c) increase in invasive species i’m not sure about b) prolonged drought i’m thinking either a) less diversity of plants or d) plant populations increase i think it is plant populations increase because ash is very good for plants to grow. many people use it as fertilizer.

A) Less diversity of plants.

Explanation:

After a volcanic eruption, lava, mud flows and ash can travel hundreds of miles. On the long term, these sediments can function as fertilizers and cause plant populations to increase. However, an initial consequence (in the short term) is less diversity of plants. This is because the mud and lava can kill plants that surround the volcano, as well as make it very difficult for these to recover.

the panel also concluded there's a better than 95 percent probability that human-produced greenhouse gases such as carbon dioxide, methane and nitrous oxide have caused much of the observed increase in earth's temperatures over the past 50 years.
