10 describe how do the locations of volcanoes relate to tectonic plate boundaries?
Answer
Answer:
Most volcanoes are located along tectonic - plate boundaries. At divergent plate boundaries, such as mid - ocean ridges, magma rises up to fill the gap as plates move apart, forming volcanoes. At convergent plate boundaries, when an oceanic plate subducts beneath a continental or another oceanic plate, the subducting plate melts due to increased heat and pressure. The molten rock (magma) then rises to the surface, creating volcanic arcs. For example, the Ring of Fire around the Pacific Ocean is a result of convergent plate boundaries with numerous active volcanoes.
Brief Explanations:
Based on plate tectonics theory, plate movements at boundaries cause magma upwelling for volcanic formation.
