In the context of plate tectonics, a plume is a column of very hot magma, much hotter than the usual temperature of the mantle, that rises through the cooler magma because the heat causes it to expand and therefore to be less dense. When the rising magma reaches the crust, it exerts force on the crust and contributes to continental drift. It can also cause volcanoes. The Hawaiian chain is an example of islands that were produced by volcanoes that were all caused by the same plume. As the crustal plate moves, the plume strikes different parts of the crust.

What is the main cause for earthquake activity in the ring of fire?
Tectonic Plate movement
Why don't transform plate movements cause a tsunami?
Tsunamis are typically triggered by vertical movement of the seafloor at a convergent plate boundary. Transform boundaries do not produce such vertical movement.
What is mantle plume?
A mantle plume is a rising mass of extra hot mantle rock. Mantle plumes are though to be the cause of volcanic activity away from plate boundaries.
What creates islands in the center of plates?
This is due to hotspots. It is a hot, rising plume of magma that will cause volcanoes and so create an island in the middle of a plate. The classic example of a hotspot is Hawaii in the middle of the Pacific Plate. Hope this helps :)
How does tectonic plate movement cause avalanches?
no depends how far you put it in and suck itt
What movement does mantle convection currents cause?
They cause plate movement. The plate movement then causes an earthquake.
What would cause a major earthquake in B.C.?
plate movement and plate tectonics
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.
Do earthquakes cause transform plate movement?
No, they don't. In fact earthquake are a result of transform plate movement.
What force cause the movement of the continent from one supercontinent to the present positions?
the movement of convection currents in the mantle is the cause of plate motion.
What forces cause the movement of the continents from one supercontinent to their present positions?
the movement of convection currents in the mantle is the cause of plate motion.
What kind of landforms can destructive plate movement cause?
Mountains, Continents, Volcanoes, Islands, and Fault Lines are the 5 landforms caused by plate movement.
What is it called when a plate movement cause rock to break?
it is called earthquake
What forces are thought to cause plate tectonic movement?
Convection currents (the movement of magma beneath the plates)
What is the main cause for earthquake activity in the ring of fire?
Tectonic Plate movement
Why don't transform plate movements cause a tsunami?
Tsunamis are typically triggered by vertical movement of the seafloor at a convergent plate boundary. Transform boundaries do not produce such vertical movement.
