These are named after the Roman god of fire and metal work, Vulcan, who was said to have had his workshop under Mount Vulcano, an island of the north coast of Sicily.
What are volcanoes?
The solid iron core that temperatures reaches 8,500 degrees Fahrenheit.

These are formed when volcanoes erupt and molten rock builds up into steep mounds.
What are mountains?
