What type of convergent plate boundary triggers the formation of active volcanoes as magma rises beneath the surface?
The type of convergent plate boundary that triggers the formation of active volcanoes is the oceanic-continental convergent boundary. In this setting, an oceanic plate subducts beneath a continental plate, leading to the melting of mantle material and the generation of magma. This rising magma can lead to volcanic activity, often resulting in the formation of volcanic arcs along the continent. An example of this is the Cascade Range in the Pacific Northwest of the United States.
What are the characteristics of divergent-boundary volcanoes and convergent boundary volcanoes?
Divergent boundary volcanoes are associated with mid-ocean ridges where tectonic plates are moving apart, resulting in upwelling magma forming new crust. These volcanoes tend to produce basaltic lava flows with gentle slopes and low viscosity. Convergent boundary volcanoes occur at subduction zones where one plate is being forced beneath another, leading to the melting of rock and explosive eruptions. These volcanoes typically produce andesitic or rhyolitic magma leading to more explosive eruptions with steep-sided cones.
What land feature does a convergent boundary form?
A convergent boundary forms land features such as mountain ranges, volcanoes, and trenches due to the collision of tectonic plates. The collision can cause one plate to be forced beneath the other in a process known as subduction, leading to the formation of these geographical features.
What plate boundary forms arcs of volcanoes and deep-ocean trenches?
A subduction zone forms arcs of volcanoes and deep-ocean trenches. In this type of plate boundary, one tectonic plate is forced beneath another, generating intense geologic activity that results in volcanic eruptions and the formation of deep trenches in the ocean floor. This process occurs where two plates converge.
What type of boundary is made when plates collide?
A convergent boundary is formed when plates collide. At this type of boundary, the denser plate sinks beneath the less dense plate in a process known as subduction. This collision often results in the formation of mountain ranges, volcanoes, and deep ocean trenches.

The cascade range volcanoes are associated with which type of plate boundary?
convergent oceanic oceanic
When one tectonic plate descends beneath another what kind of boundary is formed?
A convergent boundary is formed when one tectonic plate descends beneath another. This process is known as subduction and typically leads to the formation of deep ocean trenches and volcanic arcs.
Oceanic-continental convergent plate boundary.?
In an oceanic-continental convergent plate boundary, an oceanic plate is subducted beneath a continental plate due to differences in density. This process can lead to the formation of deep ocean trenches, volcanic arcs on the continental plate, and earthquakes. The subduction of the oceanic plate can also cause melting of rock, leading to the formation of magma that can erupt as volcanoes on the continental plate.
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.
What forms at a convergent boundary?
A convergent boundary is a place where two plates collide, which can form earthquakes from the impact, and volcanoes. Mountains can also be formed by this process. The Himalayas were formed like this.
What layer of the earth causes volcanoes?
Volcanoes are primarily caused by activity in the Earth's mantle, which is the layer located beneath the crust. Magma, which is molten rock beneath the Earth's surface, can rise through cracks in the crust, leading to volcanic eruptions. The movement of tectonic plates can also play a role in the formation of volcanoes.
What are subglacial volcanoes?
Subglacial volcanoes are volcanoes that form beneath glaciers or ice sheets. When magma rises to the surface and comes into contact with ice, it can lead to explosive interactions that result in the formation of subglacial volcanic features like tuyas, subglacial ridges, and hyaloclastite ridges.
Which boundary is known as a destructive boundary?
A destructive boundary, also known as a subduction zone, is a type of tectonic plate boundary where one plate is being forced beneath another plate. This process can lead to the formation of deep ocean trenches, volcanic arcs, and earthquakes.
