(1) At convergent boundaries (subduction zones), where one plate is being subducted (going beneath) the other.
(2) At hot spots, where a large magma plume has risen from the mantle.
(3) At divergent boundaries, where crust is moving apart, magma is wedging its way between the crust, and often erupts as a volcano.
Some people think that Volcanoes form from Earthquakes, but they don't.

ProfessorVolcanoes can form at convergent plate boundaries when one tectonic plate subducts beneath another. They can also form at divergent plate boundaries where plates move apart, allowing magma to rise and create new crust. Another way is through hot spots, where magma rises through the mantle and creates volcanoes independent of tectonic plate boundaries.
The three types of volcanoes are cinder cone, composite, and shield. Cinder Cones look like a cone-shaped mountain. A material called tephra (cinder) erupts and forms a cone-shaped mountain. Cinder cones are 100 to 400 meters tall. An example is Krakatoa Island.
Composite Volcanoes have both tephra and lava material that erupt from it. The materials layer themselves and form a huge cone-shaped mountain. Composite volcanoes are 100 to 3500 meters tall. Mount St. Helens is an example of a composite volcano.
Shield Volcanoes look like dome-shaped mountain. The mountain is formed when the lava spills out and gradually creates a dome-shaped mountain. Shield volcanoes are 9000 meters tall. Example: Hawaii Island.

What are the two major ways in which volcanoes most often form?
volcanoes takes place in two ways which are at the hotspot and at the point of weakness which are fault or crack
What is the difference between Compare volcanoes that form on land with volcanoes that form in the ocean.?
Land Volcanoes eat lamas and underwater volcanoes eat camals
Are there any kind of volcanos?
There are three different types of volcanoes. The types of volcanoes are shield volcanoes, dome volcanoes, and also composite volcanoes.
What kind of plates cause volcanoes?
Plates do not cause volcanoes. Volcanoes generally form at the boundaries between plates. They form at convergent and divergent boundaries.
What are three types of volcanoes?
Three types of volcanoes are shield volcanoes, stratovolcanoes (composite volcanoes), and cinder cone volcanoes. Shield volcanoes have gentle slopes and are formed by low-viscosity lava, while stratovolcanoes are characterized by alternating layers of lava and ash. Cinder cone volcanoes are small, steep-sided volcanoes formed by pyroclastic material ejected during eruptions.
