We are doing a report on the earth. One of the things we have to do is volcanoes. We are having trouble looking up one of the questions. This is the one question we had trouble on "What effects do volcanoes have on the earth's surface"?

Generate tourism.

Cons
Destroy old habitat and crops.
Destroy cities, towns, communities.
Displace populations.
Kill people and other animals.

I hope this helps with your report.
