silica caldera viscous denser subduction divergence hot spots earthquakes

Explanation:

The lava that has more silica content is more explosive in nature, and if a volcano magma chamber explodes and causes the collapse of the volcanoes itself is known as a caldera. The shied volcanoes carry viscous lava when it flows form the vent and subduction is the process when the oceanic plate sinks due to the process of the convergence. Divergence is created features as it lies on the west coast of the united states. Hot spots are not formed by the volcanic activity at the plate boundary. Earthquakes and volcanoes are linked with several weather events.

Can you give us more information about this question and i will try to you as much as i can

The answer is c epicenter
