Volcanic arcs are usually island arcs off the coast of a continent, while volcanic mountain ranges are usually inland inside a continent. But the volcanoes of a volcanic island arc do form an undersea volcanic mountain range. So to some extent the difference is mostly a matter of terminology.
An assignment about erupting volcanoes could include information on the causes of volcanic eruptions, types of volcanic activities (explosive vs effusive), common volcanic hazards like ash fall and pyroclastic flows, and the impact of eruptions on the environment and communities. Additionally, students could research specific historic volcanic eruptions and their consequences.
Mostly by volcanic activity.
Wind, mostly. And the moon's gravity, but mostly wind.
Mostly volcanic tuff.
Mostly volcanic eruptions or Tsunami related.
Mostly fiery death.
Fiji is primarily a volcanic island. It is part of the Ring of Fire and was formed through volcanic activity. However, there are also some coral atolls in Fiji, particularly in the Lau Group of islands.
pumic and basalt, mostly
No. It is not a compound but a mixture and is composed of mostly inorganic substances.
Yes. Pumice is inorganic. It is a glassy volcanic rock made mostly of silicates.
It is a dry remote region, mostly made of volcanic ash
