What types of materials are volcanoes like mount St.Helens made of?
Mt. St. Helens is made up of layer upon layer of Pyroclastic materials from previous eruptions. The most consistent type of lava that is seen on the flanks of the volcano is Andesite, which accounts for the history of explosive eruptions as well as the fine ash that seems to be present everywhere on the volcanoes flanks. Although there are other types of magma that contributed to the forming of the volcano, it is primarily considered to be constructed of Andesite and is therefore classified as a Stratovolcano.

Mount st. helens is an example of which of the following volcano types?
It is a strato/composite volcano
What types of materials are volcanoes like mt st helens made of?
Layers and layers of primarily felsic or intermediate-composition magma -- magma that is relatively rich in silica, sodium, aluminum, and potassium. These crystallize to form granitic rocks. These are the classic shapes of volcano that every school kid knows, known as stratovolcanoes or composite volcanoes.
What are tall cone shaped volcanoes with alternating layers of lava and ash called?
These types of volcanoes are known as Stratovolcanoes, examples of these would be Mt. Fuji (Japan), Mt. St. Helens (Washington), and Galeras (Columbia).
Why are there three types of volcanoes?
There are three types of volcanoes because each volcano is different. A shield volcano is a broader volcano that erupts lava at a slow speed, it can be avoided with a brisk walk. This volcano does not cause explosions. A cindercone volcano cause pyroclastic flows and are more rare than shield volcano, also, these volcanoes are the deadliest and cause large explosions such as the one on mount St. Helens. A composite volcano, is the two put together. It is in between on the size, and sometimes erupts lava and sometimes pyroclastic flows.
