What is it called when magma rises it carves a tube-shaped structure?
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?
Melted material that rises from the mantle is called magma. Once magma reaches the Earth's surface, it is then referred to as lava.
How is magma generated along subduction zones?
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.
New crust forms when or where?
where two plates pull apart from each other at oceanic ridges
What is the process by which new crust is created when the seafloor moves apart and magma rises up?
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.
A forms when magma slowly rises up inside the crater of a larger volcano.?
When magma slowly rises up the inside the crater of a larger volcano, it forms a Lava Dome.

What is called when new crust forms where magma rises at mid ocean ridges?
sea floor spreading
Where one tectonic plate is pushed under another magma forms and rises toward the surface form where the magma erupts as lava that builds up?
valcano
Does heated magma rise or sink?
When magma is being heated it rises. When it is cooled, it sinks.
What are the three major ways that magma form forms?
Three ways that magma form:temperaturecompositionpressureIn addition, water causes the melting temperature to lower, which causes it to melt into magma
When magma rises and bulges the crust?
Dikes and sills may form when magma rises and bulges Earth's crust.
What forms when magma slowly rises up inside the crater of a larger valcao?
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
Why does magma rise when it is nearer to the core?
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.
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.
Melted material that rises from the mantle is called?
Melted material that rises from the mantle is called magma. Once magma reaches the Earth's surface, it is then referred to as lava.
What type of mountain forms from the magma that is created by sea-floor spreading?
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.
