Answer:
Volcanoes located at subduction zones tend to release lava high in silica
Step-by-step explanation:
When the wanes are heated, they form a volcano; magma is also produced in the first stages of hotspot volcanism. However, as the heat continues to heat the level of silica rises to the surface, while the magma is growing; it melts through thick silica and forms a crust making the silica to be shallow in the chamber of magma.
The magma formed from the crust is thick similar to the magma that is formed from the subduction zone. The succession, therefore, leads to an eruption of materials created from the fluid of lava.
