What type of volcano forms at constructive plate margins?
Show answer

Show answer
Tsunamis, fires, landslides, disease, or homelessness (any two).
Why are the impacts of tectonic hazards usually greater in lower-income countries?
Show answer
Wealthier countries can afford earthquake-resistant buildings, monitoring, prediction and well-funded emergency services.
