Answer 2

Mount St. Helens is a stratovolcano, which means it is composed of layers of hardened lava, ash, and volcanic rock. Inside the volcano, there is a conduit or pipe that allows magma to rise to the surface during eruptions. The magma chamber is the reservoir of molten rock beneath the volcano where magma accumulates before being erupted.
