Volcanoes

Where does the word volcano come from? It comes from the Roman god of fire. His name was Vulcan.

A volcano is a mountain that blows its top! Hot lava pushes through the mountain. Then, it flows down the side.

Some volcanoes are millions of years old. Some sleep. Others are active. It is hard to tell when a volcano will blow.

Many volcanoes have snow. If they blow their tops, hot lava melts the snow. It burns up trees and plants, too, just like a fire.
