Volcanoes are mountains that erupt, sending ash and gases into the air. They are classified as active, dormant, or extinct based on their level of activity. Lava is the hot molten or semi-fluid rock that flows from a volcano during an eruption. Lava contains valuable minerals like gold, copper, and aluminum. There are over 1,500 volcanoes worldwide, many located along the Pacific Ring of Fire, with countries like the US, Russia, Indonesia, Iceland, Japan, and Chile having the most volcanoes.
