Volcanoes do not form in just any place. There are certain places on earth where they form.
Most volcanoes form at convergent boundaries. These boundaries are between two plates that move toward each other.
These boundaries are in form of trenches, ocean ridges and transform faults.
The area where many volcanoes have form is around the pacific plate. This area is called the Pacific Ring of Fire.
A volcano may also form at a divergent boundarywhere two plates move away from each other. When two plates pull apart, a long, deep crack called a rift is formed. Magma flows through the rift and builds up, resulting in the formation of volcanic islands.
Some volcanoes form far from the edges of a plate. The Hawaiian Islands which are volcanic islands are located in the middle of the pacific plate. Scientists believe that the islands sit on top of a hot spot under the Pacific Plate. A hot spot can melt rocks. Magma deep inside the earth flowed to the crust to form volcanoes. The volcanoes that rose above the ocean formed the Hawaiian Islands.
When the lava reaches the earth's surface it starts to cool and harden into rock. This happens every time the volcano erupts. Eventually the cooled down layers build up thus adding to the size of the volcano. To make it easier to understand, imagine grabbing a handful of sand and pouring it back onto the ground, grab another handful and pour it onto the existing mound, repeat this and then notice how it grows, this is the same principal as the volcano.
Volcanic mountains are formed by ___.
Lava
Gravity
Folding
Sliding
The awnser is Lava
You might want to double check it to see if it is correct if its not the right Qwestion or Awnser.
Volcanoes are usually formed as a result of a convergent boundary, where both plates are continental a divergent boundary, where at least one of the plates is oceanic a transform fault boundary, where both plates are oceanic a convergent boundary, where at least one of the plates is oceanic
Mountains are formed by plate tectonics colliding
volcanoes are usually the mountains,the plate boundaries colliding depend on where the volcanoes are formed so they are not purposely always formed by mountains.
Most volcanoes form at plate boundaries where melting of rock occurs in the upper mantle either as a result of thinning crust reducing pressure or from the introduction of volatiles.
Igneous rock is a result of cooled lava or magma.
Volcanoes are usually found where tectonic plates are converging or diverging.
Fumaroles are formed only when steam and hot gases are expelled from small vents, usually found on volcanoes.

Hot spot ^_^
They are formed in a very different way. Unlike usually Hawaii is on top of a "hotspot" or a very weak spot in the crust where the mantle breaks out, hardens and forms a volcano.
Igneous rock is a result of cooled lava or magma.
They are formed usually from extinct volcanoes

Fumaroles are formed only when steam and hot gases are expelled from small vents, usually found on volcanoes.
Soil is usually formed from the rock as a result of weathering of the rocks.
The island-arc volcanoes are formed from the subduction of an oceanic tectonic plate under another tectonic plate, and often parallel an oceanic trench.
it is said that Philippines was formed by volcanoes. it appears that the volcanoes underneath the ocean has the same core of the volcanoes found here in the Philippines
Not really. Earthquakes can and do occur when a volcano is forming, but the volcano is not a result of an earthquake. Volcanoes are formed when magma (molten rock) within the earth's crust reaches the surface.
