text: Magma pushes toward the surface through fissures and reaches the surface through volcanic vents.
text: When a volcano erupts, the magma rises and either gently flows onto the surface or is violently shot into the air.
text: But when the magma reaches the surfaces, another interesting thing happens.
text: As magma travels up, the temperatures drop which may cause it to solidify before it gets to the surface.
text: If magma contains dissolved gases, these will tend to bubble out when the magma comes to the surface
text: When magma erupts and flows at the surface, it is called lava.
text: Sometimes the consistency of the magma flowing to the surface becomes thick and viscous, and ends up plugging the vent as it ascends.
text: A magma without bubbles will simply ooze to the surface.
text: The magma is “lighter” than the surrounding rock, so it floats to the surface, finding its way though cracks and faults in the crust.
text: There is no guarantee that a magma will reach the surface, though.
text: When it does reach the surface, however, a volcano is formed.
text: Magma pushes toward the surface through fissures and reaches the surface through volcanic vents.
text: Magma pushes toward the surface through fissures and reaches the surface through volcanic vents.
text: Gases may be able to escape a volcano before magma reaches the surface.
text: Gases may be able to escape a volcano before magma reaches the surface.
text: Magma is called lava when it reaches the surface.
text: When magma reaches the surface and erupts from a volcano, it officially becomes lava.
text: When magma reaches the surface from beneath water or air, it is called lava.
text: Eventually it reaches the surface and erupts as a volcano.
text: Eventually, the magma reaches the surface; when it comes out, we call it an eruption.
text: Once magma reaches the surface, it becomes lava.
text: Oftentimes, gases are able to escape a volcano before magma reaches the surface in an eruption.
text: 6. magma reaches the surface erupts as lava or volcanic ash--forms when dissolved gases in the magma expand and below the magma apart into small fragments of volcanic glass.
text: Explosive eruptions result when groundwater heated by magma abruptly converts to steam and also when magma reaches the surface so that volcanic gases dissolved in the molten rock expand and escape into the air extremely rapidly.
text: If the magma contains volatile elements (water and/or gases), when it reaches the surface, these volatiles will suddenly expand into steam and gas, causing a violent eruption.
text: This texture forms when dissolved gases come out of solution and form bubbles as the magma decompresses as it reaches the surface, yet are trapped as the erupted lava hardens before the gases can escape.
text: The magmas that reach the surface build island arcs and continental margin volcanic arcs built of basalt, andesite, and rhyolite lava flows and pyroclastic material.
text: When magma reaches the surface and erupts from a volcano, it officially becomes lava.
text: Magma that flows onto the surface is called lava.
