Volcanism forms when two oceanic plates collide, causing the more dense one to subduct under the other. When it goes under, it partially melts and the magma forces upwards to create an active volcano. An active volcano will stay active until cut off from the magma. Also, the more the volcano erupts, the more crust will form, so if a volcano was once under water, an island will eventually form if not cut off from magma.
What else can I help you with?
How volcanism causes earthquake?
volcanism can not cause earthquakes
A form of volcanism that allows magma to seep into the crustal layers and harden is called?
It is called a magmatic intrusion.
Does the mantle contain volcanism?
No. Volcanism occurs at the surface on the crust. However, the magma that drives volcanism ultimately comes from the mantle.
What type of volcanism occurs underwater along the mid-oceanic ridge?
Rift volcanism.
The hawaiian isand and Yellowstone national park are associted with which of the three zones of volcanism?
hot spot volcanism
What are the 2 major ways an island is formed?
Islands can form in several ways, including rising water level, growth of coral, and volcanism.
What is the relationship between hot spots and volcanism?
Hot spots are regions in the Earth's mantle where plumes of hot material rise, leading to volcanic activity at the surface. Unlike most volcanism, which occurs at tectonic plate boundaries, hot spot volcanism can happen in the middle of tectonic plates. As the tectonic plate moves over the stationary hot spot, a series of volcanoes can form, creating a volcanic chain, such as the Hawaiian Islands. Thus, hot spots are crucial for understanding intraplate volcanism and the formation of certain volcanic features.
Is it true or false volcanism occurs on planets whose interiors have completely cooled?
Volcanism can only occur on planets with a liquid mantle.
What is the meaning of bulkanismo?
Bulkanismo is the Filipino word for volcanism. Volcanism is a phenomenon that involves the eruption of molten rock, or magma, onto the surface of the planet.
What has the author Luigi Beccaluva written?
Luigi Beccaluva has written: 'Volcanism and evolution of the African lithosphere' -- subject(s): Lithosphere, Volcanism, Geodynamics
The island of Hawaii experiences volcanism because it is located above the Mid-Pacific?
False! The island of Hawaii experiences volcanism because it is located above a hotspot in the Earth's mantle.
The most common way for mountain to form is when?
The most common way for mountains to form is when two lithospheric plates collide. This can cause volcanism and folding of rocks in the crust forming mountain belts.
