lava dome
When magma rises and carves a tube-shaped structure, it forms a volcanic conduit or lava tube. These can serve as pathways for magma to travel from the magma chamber to the surface during volcanic eruptions.
Melted material that rises from the mantle is called magma. Once magma reaches the Earth's surface, it is then referred to as lava.
Magma is generated along subduction zones when oceanic plates are forced beneath continental plates. The intense heat and pressure cause the oceanic plate to melt, creating magma that rises to the surface and forms volcanoes.
where two plates pull apart from each other at oceanic ridges
This process is called seafloor spreading. It occurs at divergent plate boundaries where tectonic plates move apart. Magma rises up from the mantle through the cracks, solidifies upon contact with the cold seawater, and forms new oceanic crust.
When magma slowly rises up the inside the crater of a larger volcano, it forms a Lava Dome.

When magma is being heated it rises. When it is cooled, it sinks.
Three ways that magma form:temperaturecompositionpressureIn addition, water causes the melting temperature to lower, which causes it to melt into magma
Dikes and sills may form when magma rises and bulges Earth's crust.
A large lava dome can be formed when magma slowly rises up inside the crater of a larger volcano. It is a roughly circular mound shaped protrusion resulting from explosion of lava from the volcano.Ê
Water that is heated expands and rises to the surface of the tray. Similarly, the magma expands and rises to the surface of the tray. Similarly, the magma nearer the core expands and rises to top of the mantle.
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.

A volcanic mountain forms from the magma that is created by sea-floor spreading. This magma rises to the surface and solidifies, creating a volcanic mountain range along the mid-ocean ridge where sea-floor spreading occurs.
