Which landform would most likely be found at a convergent subduction boundary?

convergent boundary -rift valley divergent boundary -mid-ocean ridge


What type of boundary forms when an oceanic plate is pushed under a continental plate?

A convergent boundary forms when an oceanic plate is pushed under a continental plate. This process, known as subduction, can result in the formation of deep ocean trenches, volcanic arcs, and earthquakes.


Is subduction convergent or divergent?

Subduction is a convergent boundary where one tectonic plate moves beneath another plate into the Earth's mantle. This process occurs at plate boundaries where two plates are moving towards each other.


What is the type of plate boundary where two plates move together causig one of the slabs of lithosphere to descend into the mantle beneath an overriding plate?

This type of plate boundary is called a convergent boundary or subduction zone. It occurs when two tectonic plates collide, with the denser oceanic plate being forced beneath the less dense continental plate. This process can lead to the formation of deep oceanic trenches and volcanic arcs on the overriding plate.


What plate boundery type does Mt.Pinatubo?

Mt. Pinatubo is located near a convergent plate boundary, where the Eurasian Plate is subducting beneath the Philippine Sea Plate. This subduction zone is responsible for the volcanic activity in the region.


What is the effect of plate movement at a divergent boundary?

The effect of subduction at the boundary of two plates is the movement of one tectonic plate under another tectonic plate. This creates a subduction zone, which often occurs in convergent boundaries.


Which type of plate boundary would be most likely to lead to above-ground activity?

convergent!


Would it be more likely for a major explosive eruption to occur at an ocean ridge or at a convergent ocean continental boundary?

it would be more likely to occur at convergent ocean-continental boundary beacuse the rocks are composed with a higher silica and has much thicker continental crust.


Which type of plate boundary would be most likely lead to above ground volcanic activity?

convergent!


Are the two plates along the coast of South America probably a divergent boundary or a convergent boundary?

It is a convergent boundary The subduction of the pacific plate underneath the west coast of South America creates the uplift and volcanoes that is still producing the Andean mountain range. A divergent boundary would create a mid-ocean ridge, or somthing akin to the great rift valley in Africa.


What type of volcano formation would typically be found under a convergent boundary?

A stratovolcano or composite volcano would typically be found under a convergent boundary. These volcanoes form from the intense pressure and heat generated by the subduction of one tectonic plate beneath another, leading to explosive eruptions due to the high gas content of the magma.


Which of the convergent boundaries would most likely create a non-volcanic mountain range?

A collision boundary (also known as a continent-continent convergent boundary) would most likely create a non-volcanic mountain range. When two continental plates collide, the crust crumples and folds, leading to the formation of mountain ranges like the Himalayas. This process does not typically involve volcanic activity.
