Not all dome shaped mountains are caused by magma, but some are.
There are three sorts of magma related Dome Mountains
1) They occur above some Laccoliths. Laccoliths form when magma is injected between two layers of sedimentary rock, causing the overlying strata to bulge upwards forming a dome shape (like a blister on your toe). The magma in these circumstances can be of any composition.
2) Certain magmas, when they erupt form large domes Eg Big Southern Butte. In these cases the magma is usually very acidic (very silica rich) and viscous and is called a rhyolite.
3) In many cases (quite commonly) smaller domes of semi solid magma get pushed up in the craters of existing volcanoes, either because the magma is cool or because its composition makes it viscous. The majority of the magmas are Adesitic, Dacitic or Rhyolitic in composition (but basaltic domes are also known. These domes do not survive long as topographic features.
What else can I help you with?
How a dome mountain can eventually form out of magma that are hardened beneath earth's surface?
A dome mountains forms when rising magma is blocked by horizontal layers of rock. The magma forces the layers of rock to bend upward into a dome shape. Eventually, the rock above the dome mountain wears away, living it exposed.
A forms when magma slowly rises up inside the crater of a larger volcano.?
When magma slowly rises up the inside the crater of a larger volcano, it forms a Lava Dome.
Describe how a dome mountain can eventually form out of magma that hardened beneath earths surface?
A dome mountain forms when magma is injected into the Earth's crust and starts to push upward, creating a bulge or dome shape. As the magma cools and solidifies beneath the surface, it forms a layer of hardened rock. Over time, erosion gradually removes the overlying layers, exposing the dome-shaped mountain.
When magma pushes upward it raises overlying rock layers into?
When magma pushes upward, it raises overlying rock layers into dome-like structures called volcanic domes or volcanic plugs. These features are formed as the magma forces its way through the Earth's crust and solidifies before reaching the surface.
Does A dome mountain forms when rising magma is blocked by horizontal layers of rocktrue or false?

Where do dome mountains form?
Dome mountains form when magma beneath the Earth's surface pushes up and deforms the overlying rock layers. As the magma cools and solidifies, it creates a dome-shaped structure. These mountains are typically found in areas of volcanic activity or tectonic uplift.

What magma forms underwater mountains?
Volcanoes
When magma pushes sedimentary rock upward what happens?
It forms a dome.
Do laccoliths form small dome-shaped mountains?
A dome formed by thick magma that pushes upward rather than horizontally.
How are dome mountains different from volcanic mountains?
Dome mountains are formed by the uplift of rock layers in a broad region, creating a dome-shaped structure, while volcanic mountains are formed by the accumulation of lava and volcanic ash erupting from a volcano. Dome mountains do not have volcanic activity associated with them, whereas volcanic mountains are typically associated with magma and eruptions.
What mountains form from pools of magma that accumulate underground and push up on crustal plates?
