Where does a volcano erup mostly?

Answer 1

Volcanoes normally form at or near divergent tectonic plate boundaries or convergent boundaries where subduction is occurring.

An example of a divergent plate boundary with significant volcanism is the Mid-Atlantic-Ridge. This is most obvious in Iceland.

An example of a convergent boundary would be the subduction of the Nazca Plate beneath the South American Plate to form the Andes mountain range and the volcanoes in this area.

Answer 2

The "Ring Of Fire" is a ring of volcanoes that stretches from the southern tip of south america bordering the altantic ocean and the southern tip of Africa, also bordering the atlantic. It contains most of the world's volcanoes.

Answer 3

volcanoes appear at the tectonic plat boundaries because the ocean floor dives underneath the plates holding continents because the ocean crust is denser than the continental crust and the ocean crust melts in the mantle and finds a weak point in the crust and pushes up creating a volcanic mountain range.

Answer 4

Volcanoes mostly erupt along tectonic plate boundaries, such as subduction zones and mid-ocean ridges. This is where the movement of the Earth's tectonic plates allows magma to rise to the surface, resulting in volcanic activity.

Answer 5

Most volcanoes occur at the boundaries between tectonic plates. Most on land are found at subduction zones, where one plate slides under another.

Answer 6

Along mid oceanic ridges and around the Pacific ring of fire.

Answer 7

Volcanoes mostly erupt in the Ring of Fire.
