subduction boundary eruption
What else can I help you with?
Eruptions that occur where two lithospherice plates com together?
Eruptions that occur where two lithospheric plates come together are typically explosive in nature due to the subduction of one plate beneath the other. This subduction creates magma chambers that can lead to violent eruptions, such as those seen in volcanic arcs like the Ring of Fire. The resulting volcanic activity is often associated with earthquakes and the formation of mountain ranges.
Eruptions that occur where two lithospheric plates come together?
Volcanic eruptions at plate boundaries occur when one plate subducts beneath the other, allowing magma to rise and erupt on the surface. This often leads to explosive eruptions due to the pressure buildup of gases in the magma. Additionally, the melting of the subducted plate can create a magma chamber that fuels volcanic activity.
What would be expected to occur on an extraterrestrial object that has moving lithospheric plates?
folded mountains
Where do volcanoes happpen?
Volcanic eruptions occur only in certain places and do not occur randomly. That's because the Earth's outermost shell -- the lithosphere -- is broken into a series of slabs known as lithospheric ortectonic plates. These plates are rigid, but they float on the hotter, softer layer in the Earth's mantle. There are 16 major plates. As the plates move about, they spread apart, collide, or slide past each other. Volcanoes occur most frequently at plate boundaries.
What most effectively outline the edges of the lithospheric plates?
Mid-ocean ridges and deep sea trenches (with their associated volcanos). Also in limited areas strike-slip fault systems (e.g. California), continental collision zones (e.g. India & Asia), etc.
Where do earthquakes and volcanes occur?
Earthquakes occur near faults and near the edges of plates in the earth's crust. Volcanic eruptions occur wherever a volcano is. Volcanic eruptions can occur when magma from below Earth's surface seeps through a weak spot in the crust. Volcanoes occur along plate boundaries, along the edges of plates, so this is where volcanoes occur also.
Where in the world do earthquakes and volcanoes happen?
Earthquakes occur near faults and near the edges of plates in the earth's crust. Volcanic eruptions occur wherever a volcano is. Volcanic eruptions can occur when magma from below Earth's surface seeps through a weak spot in the crust. Volcanoes occur along plate boundaries, along the edges of plates, so this is where volcanoes occur also.
When litosphereic plates meet volcanoes are often formed true or false?
True. When lithospheric plates meet, particularly at convergent or divergent boundaries, volcanic activity can occur. In convergent boundaries, one plate may be forced under another, leading to magma formation and volcanic eruptions. At divergent boundaries, as plates pull apart, magma can rise to fill the gap, also resulting in volcanic activity.
The theory of tectonic plates help to explain?
The theory of plate tectonics helps to explain how earthquakes and volcanic eruptions occur.
What type of volcanic eruptions seems to occur most often where plates are crunching together?
Stratovolcanoes are usually found along convergent plate boundaries where an ocean plate is pushed under another ocean plate or a continental plate (subduction zone). If you are referring to convergent boundaries in which neither plate is subducted but both are pushed up to form mountains, then my answer would have to be that it is very rare for a volcano to form at this type of boundary.
What delineates the edges of all lithospheric plates?
The edges of lithospheric plates are delineated by tectonic plate boundaries, which can be classified into three main types: divergent, convergent, and transform boundaries. Divergent boundaries occur where plates move apart, creating new crust, while convergent boundaries form where plates collide, leading to subduction or mountain building. Transform boundaries are characterized by plates sliding past one another horizontally. These boundaries are often associated with geological activity such as earthquakes and volcanic activity.
What type of volcanic eruptions occur most often when plates are moving apart?
Most common would be a fissure eruption of basaltic magma.
