causes of volcanoes at destructive boundaries

HideShow resource information

causes of volcanoes at destructive boundaries

1.Convection currents in the mantle converge.

2. Oceanic crust subducts underneath the continental crust.

3. Oceanic plate melts in the mantle.

4. Magma rises through fissures in the continental crust.

5.Gases such as sulphur dioxide and hydrogen chloride are released in the magma chamber.

6.Release of pressure as magma enters the magma chamber near the surface.

7. Eruption continues now vent is cleared and acid lava flows out.

8. Viscous lava doesnt flow far before solidifying.
