Answer :
Final answer:
Volcanic hazards excluding pyroclastic flows and lahars include volcanic gases affecting respiration, atmospheric cooling due to ash, and volcanically generated tsunamis.
Explanation:
Three volcanic hazards other than pyroclastic flows and lahars include the effects of volcanic gases on respiration, atmospheric cooling from ejected ash, and volcanically generated tsunamis.
These hazards are significant because they can cause respiratory problems, affect global climate, and lead to devastating waves capable of traveling long distances. It is important to note that nueé ardentes, mentioned in one of the options, is another name for a pyroclastic flow, which you've been asked to exclude from your choices.
