Which geologic process most likely caused the formation of the Mount St. Helens Volcano?

Sagot :

Answer:

High pressures and hot temperatures force molten rock to the surface.

Explanation:

In Mount St. Helens' case, an oceanic plate called Juan de Fuca slips under the North American plate, creating the Cascadia subduction zone. A continental arc brews adjacent to the subduction zone, where high pressures and hot temperatures force molten rock to the surface. The result is a chain of volcanoes.
