Yes, that's correct.
When magma rises through the Earth's crust and encounters a weaker spot, it can force its way to the surface, leading to the formation of a volcano. This process occurs when the pressure from the accumulating magma exceeds the strength of the surrounding rock, allowing it to break through. Once at the surface, the magma erupts as lava, ash, and gases, creating volcanic structures over time. The location and type of volcano formed depend on various factors, including the composition of the magma and the tectonic setting.
There are many volcanoes in Hawaii. Each island was formed by a volcano, and there are still five active volcanoes there: Loihi, Kilauea, Mauna Loa, Hualalai, and Haleakala. The Hawaiian islands are moving over what is called a "hot spot" below the earth's crust, and as the tectonic plate slides over, new volcanoes are formed.

Volcanoes are commonly found at the edges of Earth's moving plates because this is where the movement of the plates causes the Earth's crust to become thinner and more fractured. Magma from the mantle below the crust can then more easily rise up through these fractures, leading to volcanic activity. This process is known as plate tectonics.

They form the same way all volcanoes form. See related question below.
Volcanoes are essentially holes in the earths surface through which magma and lava can erupt. when pressure builds up below the earths crust, magma is then forced violently out of the volcanoes.
Iceland has about 130 volcanic mountains. About 18 have been active since human settlement. The related link below shows you where these active volcanoes are. Into Google Search type "List of volcanoes in Iceland"
