Where do most volcanoes occur quizlet?
Most volcanoes occur along diverging plate boundaries, such as the mid-ocean ridge, or in subduction zones around the edges of oceans.
Where are most volcanoes found and why?
Most volcanoes are found along convergent or divergent plate boundaries. The Pacific Ring of Fire is the most geologically active region in the world. Volcanoes such as those that form the islands of Hawaii form over hotspots, which are melting zones above mantle plumes.
What plate boundary do most volcanoes occur on?
divergent plate boundaries
Sometimes, the plates collide with one another or move apart. Volcanoes are most common in these geologically active boundaries. The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries.
What are the 3 places that volcanoes form?
There are three main places where volcanoes originate:
- Hot spots,
- Divergent plate boundaries (such as rifts and mid-ocean ridges), and.
- Convergent plate boundaries (subduction zones)
Are there volcanoes located in the middle of the continent?
Located in the eastern side of the Democratic Republic of the Congo, Nyamuragira is a volcano in the middle of the continent of Africa, near the Red…
How does a volcano occur?
Volcanoes erupt when molten rock called magma rises to the surface. As the magma rises, bubbles of gas form inside it. Runny magma erupts through openings or vents in the earth’s crust before flowing onto its surface as lava. If magma is thick, gas bubbles cannot easily escape and pressure builds up as the magma rises.
Why do most volcanoes occur at plate boundaries?
Most earthquakes and volcanoes occur because of the movement of the plates, especially as plates interact at their edges or boundaries. Volcanoes also form as magma rises upward from the underlying mantle along the gap between the two plates.

Where are the most destructive volcanoes found?
To humans, the most destructive volcano in the world is Mount Tambora in Indonesia. This volcano created the most powerful eruption in known history and killed 100,000 people along the way.
Where are volcanoes most likely to be found?
Most of the volcanoes occur at, or close to, the edges of tectonic plates. In particular, they are found along plate margins from New Zealand, along the eastern edge of Asia, then north through the Aleutian Islands (Alaska), and south down the coast of North and South America.
Where would an explosive volcano most likely occur?
Most explosive eruptions occur in volcanoes above subduction zones, where one tectonic plate dives beneath the other. Eighty to 120 kilometers below the surface, magma forms when the rocks of the mantle melt just above the subducting plate.
