The interior of the earth is extremely hot.
Due to high temperature deep inside the earth rocks turn into molten magma.
When this molten rock material is ejected to the earth’s surface during a volcanic eruption, it accumulates around the vent and may take the form of a cone.
The height of the cone increases with each eruption and it takes the form of a mountain.
As these mountains are formed by the accumulation of volcanic material, they are known as volcanic mountains or mountains of accumulation.
Examples of the mountains:
Mount Mauna Loa in Hawaii Islands
Mount Popa in Myanmar
Vesuvius in Italy
Cotopaxi in Equador
Fuji Yama in Japan
