Volcanoes are openings in the Earth’s crust that allow magma, gases, and ash to escape. They are closely connected to the movement of tectonic plates. Volcanoes are usually found in three main places: divergent plate boundaries, convergent plate boundaries, and hotspots.

At divergent boundaries, tectonic plates move apart, allowing magma to rise and form volcanoes. This happens in places like the Mid-Atlantic Ridge, where new oceanic crust is created.

At convergent boundaries, plates collide, and one plate moves under another in a process called subduction. The melting of the subducted plate forms magma that rises to create volcanoes. Many volcanoes in the Pacific Ring of Fire are formed this way.

Hotspots are areas of intense heat in the mantle where mantle plumes rise and melt the crust above them. These volcanoes are not located at plate boundaries but inside tectonic plates. The Hawaiian Islands and Yellowstone are examples of hotspot volcanoes.

In short, volcanoes are not limited to a single location. They appear at divergent boundaries, convergent boundaries, and hotspots. Understanding these locations helps explain why volcanic activity occurs around the world.

So the correct answer is All of these, because volcanoes can form in all three types of locations depending on the Earth’s internal processes.
