Some volcanoes, like the Cascade Volcanoes up in Washington and Oregon, are of the type called stratovolcano. These steep volcanoes sometimes erupt explosively, and other times have calmer lava flows that just spill out on the surface. The material from eruptions, like lava and ash, build up and cause these volcanoes to have a character like a layer cake.
