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.
The North American Plate and the Juan de Fuca Plate.
Continental plates are tectonic plates. They are tectonic plates upon which continents rest, and they move as do all tectonic plates. Basically, there is no difference, other than the fact that oceanic plates are another type of tectonic plate.
Mount St. Helens consists of lava rock interlayered with ash, pumice and deposits, together with layers of basalt and andesite.
Like most stratovolcanoes, Mount St Helens alternates between explosive and effusive eruptions.
The tectonic plates
Mount St Helens is a composite cone (strato) volcano.
