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 types of materials are volcanoes like Mount St. Helens made of?
Mount St Helens is made up of andesitic and rhyolitic pyroclastic materials.

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.
What are the different types of volcanoe?
Volcanoes are grouped into four types: cinder cones, composite volcanoes, shield volcanoes and lava volcanoes. They are: Cinder Cones: They are circular or oval cones made up of small fragments of lava from a single vent. They have been blown into the air, cooled, and fallen around the vent. Composite: They are steel-sides and composed of many layers of volcanic rocks. Mt. Rainier and Mount St. Helens are examples of this type of volcano. Shield: Shaped like a bowl or shield in the middle, they have long gentle slopes made of basaltic lava flows. The volcanoes that formed the basalt of the Columbia Plateau were shield volcanoes. Lava Volcanoes: Deep sided mound formed by lava that is too thick to flow. The lava piles up near the vent.
What might volcanoes look like afterwards?
if your talking about after an eruption, it can look the same or change significantly like Mt St Helens, the whole north face was blasted away and Krakatoa completely destroyed itself some volcanoes collapse in, and the magma chamber is emptied and compressed... forming a caldera, which can be extremely explosive however, most volcanoes remain looking the same

What year was Mount Saint Helens the volcano born?
Mount Saint Helens like all other volcanoes was created over thousands of years, it started about 37,600 years ago and still continues in it's development. The link below gives far more detailed information.
What can volcanoes do to hurt people?
Ashes might cover them like Pompeii did when it explodes like Mt St Helens and when lava pours down and burns people and house dead with a temperature of 1000 1400 Degrees Celsius
