Volcanoes - Mrs. Pechan`s Class!
... A volcano is an opening exposed on the earth’s surface where volcanic material (or magma—molten rock) is emitted. The volcanoe’s coneshaped structure is build by the accumulation of lava around it’s summit. There are many types of volcanoes. Here are some examples below that demonstrate the variou ...
