Magma is hot liquid lava that erupts out of a volcano, it's already under the entire surface of the Earth. In areas where the crust is weak, that's where the magma forms.

How do volcanoes form in the ring of fire?

Volcanoes in the Ring of Fire are formed due to the subduction of tectonic plates. In this region, the Pacific Plate is being forced beneath other plates, leading to intense geological activity that results in volcanic eruptions. This subduction process creates magma chambers beneath the Earth's crust, which can lead to the formation of volcanoes when the magma rises to the surface.


What type of plate boundary triggers the formation of active volcanoes as magma rises beneath the surface?

Oceanic-to-Oceanic plate boundary triggers the formation of active volcanoes as magma rises beneath the surface.Transform plate boundaries trigger the formation of active volcanoes as magma rises beneath the surface.


When does magma form?

Magma forms when rocks in the Earth's mantle melt due to high temperature and pressure. This typically occurs at depths of 50-200 km beneath the Earth's surface.


Why do volcanoes form above subduction zones?

Volcanoes form above subduction zones because as one tectonic plate is forced beneath another, the subducted plate melts due to the high pressure and heat. This molten rock then rises to the surface, creating magma chambers that eventually erupt as volcanoes.


Does a volcano have a hot spot?

Yes - volcanoes invariably have a hotspot beneath them - 'feeding' the crater with magma.


What is molden rock under earth's surface called?

Magma is the molten rock found beneath Earth's surface. When magma rises to the surface and erupts through volcanoes, it is referred to as lava. Magma can cool and solidify underground to form igneous rock.


What are Melted minerals?

Molten rock, or in other words, magma or lava. Magma exists beneath the Earth's surface, lava is flowing magma produced by the eruption of volcanoes.


What are subglacial volcanoes?

Subglacial volcanoes are volcanoes that form beneath glaciers or ice sheets. When magma rises to the surface and comes into contact with ice, it can lead to explosive interactions that result in the formation of subglacial volcanic features like tuyas, subglacial ridges, and hyaloclastite ridges.


What features form as a result of magma hardening beneath earth surface?

The features that form as a result of magma of magma hardening beneath the earth's surface are volcanic necks,sills and batholiths.
