Volcanoes occur in subduction zones, because when a subduction happens, the plate turns into liquid rock. There isn't enough room in under ground for all that liquid rock, so it erupts. After it erupts, it cools, and after a few times, it becomes a cone shape, forming a volcano.

What are 5 different places that volcanoes form?
Volcanoes form above plumes or "hot spots." The plate moves over this location, making a chain of volcanoes like Hawaii. Volcanoes also form around subduction zones. One plate moves under another, causing the the edges of the plate to melt making volcanoes, islands, and mountains. Volcanoes can also lie over magma chambers that have lava that leaked from the lithosphere into the crust.
Where do you find volcanoes other than Hawaii?
Volcanoes tend to form at convergent subduction boundaries and divergent plate boundaries. One good example would be the broad ring of volcanoes that have formed around the boundary of the Pacific plate. This is why this region is known as the ring of fire. There is also a very long chain of undersea volcanoes that occur at the mid ocean ridges. In some places these have formed islands such as Iceland. Where subduction occurs (along the west coast of South America, and the west coast of the USA for example) volcanoes form, e.g. Subduction zones also form volcanic island arcs such as the Aleutian island chain in Alaska.
Why do mountains sometimes build up around a volcano?
Volcanoes are places where the melted or molten part of the earth is squeezed out onto the surface. Some volcanoes are more gentle, and the lava, or molten rock, oozes out without exploding. Hawaiian volcanoes are this sort. Other volcanoes are very explosive, sometimes blowing off their entire tops in one huge eruption, like Mt. St. Helens in the US. Volcanoes build up into mountains because as the lava flows out, it hardens into rock. The more lava that comes out, the higher the rock pile!
What is land rising high above the land around it called?
Land rising high above the land around it is called a mountain.
When are cone shaped volcanoes created?
Cone-shaped volcanoes are created when eruptions release thick lava that solidifies quickly, building up in layers around the vent. These types of volcanoes are typically found at subduction zones where one tectonic plate is forced beneath another. Over time, repeated eruptions build up the characteristic cone shape.
How does subduction contribute to the formation of mountains?
Subduction occurs when one tectonic plate moves beneath another, causing the Earth's crust to fold and push upwards, forming mountains. This process is a key factor in the creation of mountain ranges around the world.
Where is andesitic magma found?
Andesitic magma is commonly found in subduction zones where oceanic crust is being forced beneath continental crust. These environments are typically associated with volcanic arcs and stratovolcanoes. Examples of where andesitic magma is found include the Andes Mountains in South America and the Cascades in the western United States.
Why is the ring of fire a prime location for active volcanoes?
The Ring of Fire is the result of the Pacific Plate and several smaller Oceanic plate producing many subduction zones around the rim of the Pacific Ocean. Subduction Zones are the primary producers of volcanoes on land.
What are 3 kind of volcanoes?
There are 3 kinds of volcanoes which are found around the world. They are shield volcanoes, cinder cone volcanoes, and composite volcanoes. Many of the most beautiful mountains in the world are composite volcanoes.

Volcanos form a ring of fire around the plate boundaries in the pacific ocean how might this provide evidence that the plates are moving?
Volcanoes are ofrenda found in subduction
What plate was the Rocky Mountains formed on?
The Rocky Mountains were primarily formed as a result of tectonic activity associated with the North American Plate. This mountain range was created through processes such as subduction and continental collision, which began around 80 million years ago during the Laramide Orogeny. The interactions with surrounding plates, particularly the Farallon Plate, played a significant role in the uplift and formation of the mountains.

What causes the formation of the Ring of Fire?
Volcanoes around the Ring of Fire occur mainly where moving plates collide
