- Volcanic activity frequently occurs at the boundaries of the Earth's tectonic plates which are a series of large blocks moving between each other. The movement of these plates plays a significant role in the type of volcano formed, which influences its shape.

Plate Tectonics, Earthquakes, and Volcanoes Volcanoes result when magma rises to the Earth's surface. One process that results in magma being formed, is the melting of tectonic plates being subducted. Therefore, most volcanoes are likely to occur along convergent or divergent tectonic plate boundaries.Diagram of the Pacific Rim of Fire.andforms seen in the area of covergent plate boundaries include mountains and/or volcanoes. Volcanoes may form because the subducting plate is melted to form magma, which rises and is then released in a volcano.

An example of a convergent boundary is? As a result of pressure, friction, and plate material melting in the mantle, earthquakes and volcanoes are common near convergent boundaries. When two plates move towards one another, they form either a subduction zone or a continental collision.This depends on the nature of the plates involved.s a result of pressure, friction, and plate material melting in the mantle, earthquakes and volcanoes are common near convergent boundaries.

- Associated landforms: young fold mountains, rift valleys, ocean ridges, deep sea trenches and island arcs. . Volcanoes and earthquakes mainly occur along plate boundaries where magma can escape from the earth s mantle or where stresses build up between 2 plates rubbing together.

Earth's Formation Collsions of oceanic lithosphere and continental lithosphere at convergent boundaries form deep-ocean trenches. However, collisions of two plates made of continental lithosphere at convergent boundaries may cause large mountain ranges to form. Explain why the results of the two collisions differ Because when two plates collide they will both push up to make mountains.

Types Of Volcanoes At Divergent Boundaries Types of volcanoes at divergent boundaries are the boundaries of tectonic plates of earth where two plates will be diverging and drifting apart from each other. The divergent plate boundaries cause the earth surface to ruptures and openings and eventually lead to eruption of magma contents.

The Forces that Change the Face of Earth Most volcanoes occur at plate boundaries, where two plates are moving away (diverging) or together (converging). A few volcanoes like the Hawaiian Islands form from a hot spot, or a weak spot in earth’s crust, where magma forces its way to the surface.

Why do most volcanoes and earthquakes occur at plate boundaries? This is a fairly good basic analogy to why most of the geologic activity happens at the plate margins: the collision of the plates is the driving force for most of the events we are concerned with-namely earthquakes and volcanoes.

Plate tectonics, volcanoes and earthquakes In this process, water is also being subducted with the oceanic plate. Friction increases the heat along such boundaries, which causes this material to melt and mix the oceanic plate material, the continental plate material and the water. Andesite volcanoes tend to form at these subduction boundaries.riction increases the heat along such boundaries, which causes this material to melt and mix the oceanic plate material, the continental plate material and the water.

Volcanoes related to plateboundaries Volcanoes occur along both subduction and rift zones but are generally absent along strike-slip plate margins. Most subduction-related volcanoes are explosive and build stratovolcanoes, while rift volcanoes tend to be more effusive and build shield volcanoes, though there are exceptions to both these generalities.

Earthâs crust Britannica does not currently have an article on this topic. Volcanic activity and the Earth's tectonic plates Stratovolcanoes tend to form at subduction zones, or convergent plate margins, where an oceanic plate slides beneath a continental plate and contributes to the rise of magma to the surface. At rift zones, or divergent margins, shield volcanoes tend to form as two oceanic plates pull slowly apart and magma effuses upward through the gap.

- Section 2 Types of Volcanoes Key Concept Tectonic plate motions can result in volcanic activity at plate boundaries. What You Will Learn • Nonexplosive eruptions of basaltic magma occur at divergent boundaries. • Shield volcanoes that form from enormous volumes of basaltic magma occur at hot spots. • Explosive eruptions of silica-rich magma occur at convergent boundaries. Why It Matters Knowing the tectonic setting of a volcano helps scientists predict the type of eruption that the volcano may produce. The process of magma formation is different at each type of plate boundary, where the tectonic setting is unique. Therefore, the composition of magma differs in each of these settings. As a result, tectonic settings determine the types of volcanoes that form and the types of eruptions that take place.

- The volcanoes in this region form a belt called the Ring of Fire. Some of these volcanoes are found in the western United States and Canada. 2. Volcanoes at Divergent Boundaries Volcanoes also form along divergent boundaries where tectonic plates pull apart, allowing magma to rise from the mantle.

Volcanoes Volcanoes form in three different tectonic settings. Subduction zone volcanoes form at the boundaries of two plates where one plate overrides another. Subduction zone volcanoes are the most violent and destructive of the volcanic types.Mt. St. Helens, Mt. Pinatubo, Krakatoa, and Mt. Vesuvius are all famous explosive subduction zone volcanoes.olcanoes form in three different tectonic settings. Subduction zone volcanoes form at the boundaries of two plates where one plate overrides another. Subduction zone volcanoes are the most violent and destructive of the volcanic types.

- Why do volcanoes form at convergent boundaries instead of divergent boundaries? Volcanoes form at both convergent and divergent boundaries. At convergent boundaries (except those involving two continental plates) one plate slides under another, introducin … g volatiles into the mantle, which allows some of it to melt and rise to form volcanoes. At divergent plate boundaries the young, thin crust reduces pressure on the upper mantle, reducing melting points and allowing magma to form. However, most volcanoes at divergent boundaries are deep underwater and so they ...

How are earthquakes, volcanoes, and mountains related to plate boundaries? Best Answer: Earthquakes commonly occure when the plates collide, volcanoes are caused by the spaces between the plates where the magma flows between them and rises to the surface, and mountains are a result of a plate running over another one (so to speak) and the result is that it thrusts the land up.ell convergent boundarie(a plae where plates that move towards one another) one moves beneath the other one, thus forming mountains and volcanoes.... and transfrom boundaries(where two plates grind or slide against eah other) can be a fault line causing earthquakes.
