This depends upon the viscosity (i.e. how runny the lava is ) and the composition (i.e. the percentage composition of silicon which determines the properties of the lava and how much gas is retained within the lava) of the magma greatly. In Iceland, Hekla is an example of a mountain/volcano and is classed as a shield volcano as it had long, gently inclined sides. However, in Peru where the Nazca plate is being subducted beneath the South American plate rhyolitic eruptions produce steeply sided mountains with thrust faults. The type of the tectonic plate margin determines the type of mountains produced as well as the viscosity and composition.

What are the types of mountains?
There are three main types of mountains. block mountains formed by sections of the earth's crust that have been tilted or lifted up by the movement of two close fault lines, large cracks in the earth's surface. These are usually smaller than other types of mountains and are often separated by valleys. Volcanic mountains are formed by magma that is pushed out of the earth through a crack or weak place in the earth's crust. Fold mountains are formed when rock is "squeezed" together. When plates collide, the rock along the edges crumples, creating a huge zig-zag pattern in layers of the earth's crust. Upwarped mountains are formed when magma pushes up the earth's crust without breaking the surface. This creates a rounded mountain that gently slopes toward the surrounding land.
Is sedimentary better than volcanic rock?
It depends on the specific application or use. Sedimentary rocks are formed from the accumulation of sediments and can be more easily broken down and compacted. They often contain fossils and organic matter. Volcanic rocks are formed from volcanic activity and can be more resistant to weathering and erosion. They often have a more uniform composition and can be more durable. Ultimately, the better choice will depend on factors such as strength, density, and aesthetic preference.
Are all mountains formed by volcanoes?
No, most mountains are formed from rocks squashed up as the continents move round the Earth furthermore, not every volcano is a mountain - for instance Yellowstone park is a volcano and it is not a mountain.
When are island arc volcanoes formed?
The island-arc volcanoes are formed from the subduction of an oceanic tectonic plate under another tectonic plate, and often parallel an oceanic trench.
What often occurs where an oceanic plate pushes under a continental plate?
This usually is where and how mountains ranges are formed. Volcanism can also result from the subduction melting of the oceanic crust.

What is the area that creates volcanic mountains?
There are two areas where volcanic mountains often form. They are subduction zones and hot spots.

Why are volcanic rocks often exposed at Earth's surface as hills ridges and mountains surrounded by areas of lower elevation?
Volcanic rocks are often more resistant to erosion than surrounding rock
What happens when two plates collide?
They create a convergent boundary and can often create mountains, over a period of years.
What are the different types of mountain?
There are three main types of mountains. block mountains formed by sections of the earth's crust that have been tilted or lifted up by the movement of two close fault lines, large cracks in the earth's surface. These are usually smaller than other types of mountains and are often separated by valleys.

What are the four types of mountains and some examples of them?
Fault-block mountains formed by section of the earth's crust that have been tilted or lifted up by the movement of two close fault lines, large cracks in the earth's surface. these are usually smaller than other types of mountains and are often separated by valleys. other types of mountains are unwarped and volcanic. Volcanic mountains are formed by magma that is pushed out of the earth through a crack or weak place in the earth's crust. examples: East African Rift, Death ValleyFold mountains are formed when rock is "squeezed" together. When plates collide, the rock along the edges crumples, creating a huge up and down pattern in layers of the earth's crust. examples: Jura mountains, Ridge and Valley AppalachiansDome mountains are formed when magma pushes up the earth's crust without breaking the surface. This creates a rounded mountin that gently slopes toward the surrounding land and the magma under hardens. examples: Navajo Mountain in Utah, Bear Butte in South DakotaVolcanic mountian starts out as a simple crack in the Earth called a volcanic vent. Magma erupts out of the ground as volcanoe flows, clouds of ash, and explosions of rock. This material falls back to Earth around the vent, and piles up around it. Over time (and sometimes quite quickly) a volcanic mountain builds up, with the familiar cone shape. examples: Mt. Fuji, Mt. Vesuvius (I hoped this helped)

How often should you remove the wax buildup in your ear canal?
as often as possible
What famous mountains are in New Zealand?
Mt Cook/Aoraki is the tallest, Mitre Peak at Milford Sound (Piopiotahi) is often photographed. Mt Ruapehu in the Central Volcanic group, is notable as the highest peak in the North Island, and as well as being volcanic, has a lake in its crater.
