Can a mountain turn into a volcano?
Mystery Science・2 minutes read
Mountains can be volcanoes if they are made of volcanic rock, with examples such as Heimay, Mount Lassen, and Mount St. Helens displaying volcanic activity and eruptions in the past. Mountains like Mount Everest, on the other hand, are not volcanoes but contain fossils of oceanic animals, and extinct volcanoes in unexpected places like Missouri and Virginia are unlikely to erupt again.
Insights
- Mountains can be formed from volcanic eruptions, such as Heimay in Iceland, which erupted in 1973, showcasing how volcanic activity can lead to the creation of islands and mountains through solidified lava.
- Identifying volcanic rock in mountains like Mount Lassen or Mount St. Helens in the U.S. can indicate their volcanic nature, emphasizing the importance of examining rock types to discern whether a mountain is a volcano or not, with extinct volcanoes still prevalent in various unexpected locations.

"Volcanic Mountains: Clues in Rock Types"
- Heimay, an island off Iceland, is actually a mountain that erupted in 1973, turning into a volcano temporarily, with the eruption lasting six months and resulting in the island growing due to solidified lava.
- Many mountains in California, Oregon, and Washington are volcanoes, such as Mount Lassen, Mount St. Helens, Mount Rainier, and Mount Hood, with volcanic activity in the past indicating their volcanic nature.
- To determine if a mountain is a volcano, one can examine the type of rock it is made of, with volcanic rock like basalt suggesting a potential for volcanic activity, while mountains like Mount Everest are not volcanic and contain fossils of oceanic animals.
- Some mountains in unexpected places, like the Saint Francois Mountains in Missouri and small mountains in Virginia, are made of volcanic rock from extinct volcanoes, which are unlikely to erupt again.
- While not all mountains are volcanoes, many are, and clues to their volcanic nature can be found by identifying volcanic rock, with extinct volcanoes being common and unlikely to erupt again.
