Volcanic mountains form when molten rock (magma) rises from the Earth's mantle and erupts onto the surface through a vent or opening in the Earth's crust. Over time, repeated eruptions build up layers of solidified lava and volcanic ash, creating a conical mountain shape. The accumulation of these materials over many eruptions results in the formation of a volcanic mountain.
What else can I help you with?
Steep-sided islands are sometimes formed by sea mounts?
That's correct! Steep-sided islands, such as volcanic islands, can form from the gradual or abrupt emergence of seamounts due to volcanic activity on the ocean floor. As the seamount grows and breaches the ocean surface, it can eventually develop into an island with steep sides due to the accumulation of volcanic materials.
Which of these is not a form of volcanic material?
Basalt is not a form of volcanic material; it is a type of rock that is formed from solidified lava. Volcanic materials typically include lava, ash, and tephra, which are all products of volcanic eruptions.
Where d volcanic belts from?
Volcanic belts form along the boundaries of the plates where converging boundaries push together and divergent boundaries pull apart. Volcanoes can form because of hot spots in the mantle of the Earth. Solid materials, like magma, that melt in the Earth's crust rise and can form volcanic belts.
What features form at a hot spot.?
They form volcanic mountains by heating magma that breaks through the crust. On the oceanic plates, these crustal hot spots can form chains of volcanic islands such as the Hawaiian Islands.
What is the differences between volcanic island arcs and volcanic arcs?
Volcanic arcs form at plate subduction zones. Island arcs are volcanic islands that form over "hot spots" in the Earth's mantle. Because the islands are moving with the oceanic plate, they eventually are removed from the hot spot, forming a chain of islands in the direction of the plate movement.
How do sea mounts become volcanic islands?
First of all there are different kinds of sea mounts, in reference to your question it would have to be a volcanic sea mount to begin with. It would become a volcanic island by continuing to erupt until it broke the surface of the ocean. Some excellent examples of volcanic sea mounts that became volcanic islands are the Hawaiian Islands
What volcano live in under the sea?
Many, they are called volcanic undersea mounts.
Steep-sided islands are sometimes formed by sea mounts?
That's correct! Steep-sided islands, such as volcanic islands, can form from the gradual or abrupt emergence of seamounts due to volcanic activity on the ocean floor. As the seamount grows and breaches the ocean surface, it can eventually develop into an island with steep sides due to the accumulation of volcanic materials.
What causes the formation of sea mounts?
They are volcanic in origin, conical in shape and at least 1000 metres above the ocean floor

How did the galapagos form?
They are volcanic
What does a volcanic crater form?
It forms by volcanic activity in the vent of a volcano.
How does volcanic rock form?
Volcanic rock forms by lava that has come from a volcano, cools and solidifies to form the rock.
Is a volcanic island transform?
No. Volcanoes do not form at transform boundaries. Volcanic islands can form at convergent boundaries and at hot spots.
