∙ 12y agoMagma is filled with gases and will always try to force its way up. Sometimes it breaks the surface and flows across it until the lava cools to form solid rock. Often it cools before it gets to the surface, sometimes in the vent of a dying volcano. Over the years the softer rocks of the walls erode away. leaving a 'volcanic plug' where the vent once stood.

∙ 9y agoPlinian is not a kind of volcano but a kind of volcanic eruption. Plinian is the most violent of the five main types of magmatic eruption. In these eruptions explosions powered by gas trapped in magma create a massive plume of hot ash, gas, and cinders that rises miles into the sky. Ash can fall across braugh regions like snow. Closer to the vent there may be pyroclastic flows, fast-moving, superheated avalanches of ash, rock, and gas that scorch everything in their path. In some of the larger plinian eruptions the ash cloud will spread out at high altitude, shrouding large areas in complete darkness. The term Plinian comes from Pliny the Younger, a Roman who wrote the first detailed description of such an event after he witnessed the infamous eruption of Mount Vesuvius in 79 AD.

What happens as a tectonic plate moves over a plume?
A volcano. In the middle of an ocean, it also sometimes forms islands (like Hawaii)
Why are the Hawaiian Islands in the middle of the Pacific Plate?
The Hawaiian islands are not the result of plate techtonics, they are the result of volcanic activity relating to a particular hot spot in the Earth's mantle, from which a plume of hot magma rises upward and causes volcanic eruptions.
How do you briefly explain how volcanoes that are located in hot spots formed?
As tectonic plate moves over a mantle plume, rising magma causes a chain of volcanic islands to form.
When volcanic island chain are formed what moves?
The mantle plume
When mount st helens erupted did it form the hawiian islands?
No. The Hawaiian islands are formed by a mantle plume.

What is the name of the cloud that volcanos make when they erupt?
The cloud of ash, gas, and rock fragments that is produced during a volcanic eruption is called a volcanic plume or eruption cloud.
Is a gas plume considered a volcanic eruption?
no
Why are the Hawaiian Islands in the middle of the Pacific Plate?
The Hawaiian islands are not the result of plate techtonics, they are the result of volcanic activity relating to a particular hot spot in the Earth's mantle, from which a plume of hot magma rises upward and causes volcanic eruptions.
How did the Hawaiian chain island form?
The Hawaiian Island chain formed from a mantle plume and moving plates. The rising mantle plume causes crustal material to melt at depth, which results in volcanism and finally in the formation of a volcanic island. Since the Pacific Plate is in continuous (although slow) movement, the same mantle plume will cause volcanism subsequently in different places and this is expressed at the surface as a chain of volcanoes or volcanic islands.

The mantle plume
What type of landform is formed by a mantle plume?
Hot spot and izzi rocks
What is a volcanic area on a plate where plume of mantle material rises?
Mantle plum
What does an archipelago look like?

Canary Islands Hot Spot?
The Canary hotspot is an area located just off of the northwestern coast of Africa within the Canary Islands. This is made up of a volcanic hotspot that has an underlying mantle plume that is considered to be quite deep under the earthâ??s surface.
What island has both a mantle plume and mid-ocean-ridge as its volcanic system?
Iceland.
