A composite volcano.
Mount St. Helens is a stratovolcano, also known as a composite volcano. This type of volcano is characterized by its steep slopes and explosive eruptions due to a mixture of lava flows and pyroclastic material.
The 1980 eruption of Mount St. Helens was a explosive eruption caused by a lateral blast. It was triggered by a massive collapse of the volcano's north flank, releasing pressure built up within the volcano.
The name "Vulcan" was derived from Vulcanus, the Roman god of fire and volcanoes.
Volcanic mountains form with little deformation as they are created from the eruption of magma onto the Earth's surface. These mountains are generally characterized by steep slopes and a conical shape due to the accumulation of solidified lava and volcanic ash. Examples include Mount St. Helens in the United States and Mount Fuji in Japan.
Mt. Hood is an example of a convergent boundary, where the North American Plate is colliding with the Juan de Fuca Plate, leading to the formation of the Cascade Mountain Range.

Yes. Forests grew on portions of the slopes of Mount St. Helens but were wiped out by the 1980 eruption. Some life has returned to the lower slopes.

Like most stratovolcanoes, Mount St Helens alternates between explosive and effusive eruptions.
On a continental plate. Mount Saint Helens is on a convergent plate boundary. The Juan de Fuca plate is being pushed under the North American Plate.
